Why Won't My Car Start?

When your engine cranks but won't start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating pinch. The nigh mutual causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). Nevertheless, the source may also be a mechanical fault (for example, a leaking valve), or faulty components in other systems.

What "crank-no-starting time" doesn't more often than not mean is a problem with the starter. If the engine cranks ordinarily, you don't take a starting problem.

Your car engine needs fuel, compression, and a spark to start. — Your auto engine needs fuel, compression, and a spark to beginning.

If information technology isn't cranking right (the engine rotates slowly or doesn't rotate, or you hear weird noises or nix when you lot try to start the engine), check this other applied guide to troubleshooting the starting organisation.

Whatever you practise, avoid cranking the engine repeatedly with the promise that the engine will fire up. You lot may bleed your bombardment of power and damage the starter motor in the process. Instead, try to employ the charge left in your battery to locate the fault. In this article, I offering the following:

Quick Diagnostic Tests
Do You Have Spark?
Is Fuel Reaching the Cylinders?
Practise You Take Proper Pinch?
Other Possible Components That May Cause a No-Start Condition

This guide will kickoff requite you six quick things you tin bank check, and then 3 systems to troubleshoot—the spark, the fuel, the pinch—using some simple and quick diagnostics. Then, for more than help, you lot'll see a list of components in related systems that can be associated with a no-get-go condition.

one. Six Quick Checks (Check These Start)

When trying to find out why your car doesn't want to start, continue in heed these possibilities.

Fuel

For example, brand sure there's actually fuel in the tank.

Scan the Computer Memory

The computer in modern vehicles monitors and controls a good number of sensors and actuators. Scan your computer retentiveness for problem codes before y'all do anything else. Even if the check engine calorie-free hasn't come on, you may discover a pending code that can guide you in your diagnosis. Faux input or lack of input from sensors like the crankshaft position sensor (CKP) or camshaft position sensor (CPS) can forbid the engine from starting. Also, a bad throttle position sensor (TPS) may cut off the spark to the cylinders.

Battery

If the engine cranks slowly, you may be dealing with a discharged battery, loose or corroded battery terminals, or starting system wires

Starting Organization

Problems with the starter motor or circuit tin can prevent the engine from starting. You lot may desire to cheque the circuit voltage drop or have the starter motor checked. Pay special attending to unusual dissonance when cranking.

Security System

Many modern vehicles come up equipped with an engine immobilizer as an anti-theft security organisation. The car's security system may have made an mistake that disabled the fuel or ignition arrangement or the bit in the key may have failed. To troubleshoot a built-in security system, consult your automobile owner's transmission or consult with the store that installed your alarm system.

ii. Do You Have Spark?

Commencement, y'all want to check that a good spark is reaching the cylinders. Y'all tin can do this examination without a spark tester, but it's better to employ 1 because a weak spark too as a missing spark tin can preclude your engine from starting. If possible, use an adjustable tester so that you can examination for 40KV, 30KV, and 10KV spark.

Select an easy-to-achieve spark plug and unplug the spark plug wire, or coil wire, or curlicue on plug (COP).
Fix the spark tester to 40KV, and plug information technology in at the finish of the spark plug wire or coil wire. Hook the spark tester to engine ground. To ground the tester, employ an unpainted bracket or bolt on the engine. Note: If you are not using a spark tester, grab the wire with a pair of insulated pliers and place the tip of the wire about half an inch from the basis (engine block, bracket, cylinder head). Y'all notwithstanding need a helper to crank the engine for you. The rest of the test is the same. You'll exist able to test for the presence of spark but non its strength.
While watching the spark tester, have an banana crank the engine.
You should see a vivid spark jumping the gap in the spark tester.

If you lot don't see a spark, echo the test. This fourth dimension, suit the spark tester to 30KV. If you still don't run into a spark, repeat the examination and set the tester to 10KV. If this time you see a spark or no spark, you have a problem with the ignition system. Consult your vehicle repair manual for your particular model for further diagnosis. Depending on your particular model, y'all may have a problem with an ignition gyre, distributor, ignition module, igniter, or some other related component.

Other Spark Checks You Should Do

On systems with a distributor: Check that the distributor cap isn't loose; audit the distributor cap for moisture, cracks, carbon traces, or some other harm; there could be faulty distributor components.
If you haven't replaced the spark plug wires in more than three years, your wires may be worn.
As well, check your auto owner'southward transmission or vehicle repair manual for the interval schedule for the spark plugs. Y'all may need to service (gap bank check and aligning) or supersede the plugs.
If you installed new spark plugs and your car refused to start right after, double-cheque that you installed the right plugs for your vehicle model, and the plugs have the correct gap. Use a wire feeler gauge to cheque and adjust the gap.

Fuel injectors may clog and prevent your engine from starting.

3. Is Fuel Reaching the Cylinders?

After checking for spark, you need to check that the engine is getting fuel.

How to Check a Carburetor or Throttle Torso Injection (TBI) System

Take the hat off the air filter box and open the throttle plate (carburetor). On TBI systems, lookout man the fuel injector.
Inquire an assistant to creepo the engine and come across if fuel is existence fed into the unit.
If you don't see fuel being injected, your problem is in the fuel system. Make certain of the following:

you lot take enough fuel in the tank,
the fuel pump is working,
the fuel filter is not clogged (consult your car owner'due south manual or repair transmission for the service schedule),
the fuel pressure regulator is working properly
the fuel injectors are not clogged.

How to Bank check a Multiport Fuel Injection Arrangement

Outset, make certain the fuel pump is working. Momentarily remove the fuel filler cap.
Inquire an assistant to turn the ignition cardinal to the On position, but don't start the engine.
Equally your assistant turns the key, listen closely through the filler neck of the fuel tank. Y'all should hear the whirring sound of the fuel pump motor existence energized for two or three seconds. If you hear the audio, at to the lowest degree you lot know the pump is getting power; continue with the next pace. Otherwise, yous may exist dealing with a faulty fuel pump or relay, a diddled fuse, an electrical open or another problem in the fuel pump circuit.
Detach the air cleaner assembly from the throttle body.
Open the throttle plate and spray some starting fluid into the throttle body.
Crank the engine.
If the engine still doesn't seem like it wants to start, probably fuel is getting into the cylinders and your issues lie somewhere else. However, if the engine runs momentarily and dies, then the problem is that fuel is not getting to the cylinders. Check for a clogged fuel filter, or a bad fuel pressure regulator. Consult your vehicle repair manual, if necessary.
If the incoming fuel line that goes to the fuel injectors has a test port (Schrader valve—a valve like to the one on your tires), apply a pocket-sized screwdriver to press on the valve. Be ready with a shop rag to catch the fuel.
Turn the ignition central to the On position for ii or three seconds and and so turn information technology off. Repeat the footstep two more times to prime the line with fuel.
And so, press the valve with the screwdriver while catching the fuel with the shop rag. Fuel should squirt out through the valve. Instead, if a dribble of fuel comes out or no fuel, and so check for a clogged fuel filter, a bad fuel pump, or a leaking fuel pressure regulator.
If fuel squirts through the valve, plug a fuel pressure approximate to the test fitting valve and turn the ignition fundamental to the On position and read the gauge. And then take an assistant crank the engine and read the approximate.
Compare your approximate readings to the pressure specification listed in your vehicle repair manual.
If the force per unit area is lower than specification, your problem lies in the fuel system, peradventure a faulty fuel pump, clogging fuel filter, or bad fuel pressure regulator. Detach the vacuum hose from the peak of the fuel force per unit area regulator. If the line is wet and smells like fuel, replace the fuel pressure regulator.
If the pressure is within specifications, y'all can unplug a fuel injector electrical connector and plug in a nod low-cal to the harness connector (y'all may loan a set of nod lights from your local auto parts store).
Ask your banana to creepo the engine, while you sentry the nod light.
If the nod light flashes while the engine is existence cranked, you lot tin at least assume that the injectors are receiving the pulse signal from the computer. If not, you lot need to bank check for a blown fuse or bad relay in the fuel injection system, a trouble with the computer control, or problems with input sensors (for example the crankshaft or camshaft position sensors). Scan your computer for trouble codes. Refer to the listing of related components beneath.

Some Cars Automatically Close off the Fuel Pump Later a Crash

Some models, like many Ford vehicles, have a fuel pump switch (inertia switch), that automatically cuts power to the fuel pump when involved in an accident. If your engine refused to get-go after an accident or after a vehicle struck yours in a parking lot, check for an inertia switch. The switch helps prevent your car from catching on burn if an accident occurs. Check your car owner'due south manual or vehicle repair manual to locate the switch. You tin popular the push button dorsum in manually.

4. Do You lot Have Proper Compression?

Compression in the cylinder heats up the air-fuel mixture and helps the spark ignite the mixture then the combustion takes place. During the combustion process, though, at that place should be no air leaks. Otherwise, the cylinder volition accept poor combustion, or it will not happen.

The most mutual source of air (combustion) leak is a jumped timing belt or concatenation that allows air to escape through a valve; information technology can also happen because of a burned valve, worn-out compression rings, or a blown caput gasket.

A timing belt or concatenation synchronizes the camshaft to crankshaft rotation. Subsequently miles of service, it wears down, becomes damaged, or breaks. So car manufacturers suggest replacing a timing chugalug every five years. A timing chain may have a wider service schedule interval. Replacing the belt or chain at the suggested interval can forbid serious engine mechanical issues. Consult your vehicle repair transmission.

On some vehicle models, it is easy to remove the timing cover to check if the belt or chain is even so in place. If it is, you may be able to visually inspect the belt or concatenation condition, so check that information technology hasn't jumped. Follow the instructions in your vehicle repair manual.

Also, you can cheque pinch pressure using a pinch gauge. If you take a gasoline engine, yous spiral the judge into a spark plug hole; on diesel engines, screw the gauge in place of a glow plug or injector nozzle. Follow the instructions in your vehicle repair manual.

Gasoline engine pinch ranges from 130 to 180 pounds per square inch (psi); diesel engine compression may range from 250 to 400 psi.

5. Other Components That May Cause a No-Start Status

Faults in other systems, non only ignition, fuel, or compression problems, can prevent your engine from starting. A system component itself may be faulty, or in that location may be a trouble with its wire connector or harness. Yous may need to aggrandize your diagnostic procedure to the components below.

Computers in modernistic vehicles monitor many of these components (usually in emission-related systems) and tin set problem codes when problems arise. So don't forget to scan your computer.

ane. EGR

The frazzle gas recirculation (EGR) valve introduces a measured amount of exhaust gases into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. But the valve tin fail and stick either open or closed. When the valve sticks open it may forbid your engine from starting. Other symptoms of a stuck-open EGR valve include rough idle and stalling.

two. Cold Injector

Some vehicle models employ a cold-commencement injector. It operates as a regular injector, but but works when the engine is common cold. The injector may have its own thermo switch or may be allowable past the arrangement command module. If either the switch or the computer circuit fails, you may have a difficult time starting the engine during cold months. Consult your vehicle repair manual, if necessary.

3. MAP

The manifold absolute pressure level (MAP) sensor compares the barometric (atmospheric) pressure to the intake manifold vacuum. When the sensor fails, it can prevent your engine from starting. Not all vehicles utilise this sensor. Consult your vehicle repair manual.

4. MAF

The mass airflow (MAF) sensor tells the computer the amount (the density) of the air entering the engine. A common MAF problem is a clay or foreign matter blocking the sensing chemical element, preventing the sensor from working. Or the sensor itself may fail after miles of service. Yous can make clean and test the sensor at dwelling house.

v. ECT

The estimator uses the engine coolant temperature (ECT) sensor to know how much fuel the engine needs and when to enter closed loop operation (that is, when the engine has reached operating temperature). Depending on your particular model, a bad ECT sensor can upset ignition timing or the performance of the transmission or cooling fan. Consult your vehicle repair manual, if necessary.

6. Canister Vent Valve

The canister vent valve is part of the evaporative emissions control (EVAP) system. The EVAP system temporarily stores harmful fuel vapors into a canister to preclude their release into the atmosphere. When conditions are appropriate, the computer routes the fuel vapors out of the canister through a canister vent valve and into the intake manifold for called-for. A faulty valve, though, can prevent the engine from starting. Consult your vehicle repair manual for the process to examination the valve.

7. TPS

The throttle position sensor (TPS) monitors the position of the throttle valve. It sends a voltage signal to the estimator. The figurer uses this information to regulate the air-fuel mixture according to engine needs. On some vehicle models, a worn-out, declining or bad TPS volition prevent your engine from starting at all.

8. Vacuum Leaks

Vacuum leaks are not uncommon, and they are the source of many engine functioning issues, including failure to start. Depending on where the fault is located, vacuum leaks can be hard to observe. But major vacuum leaks that tin make the engine hard to start may happen in the power booster vacuum hose, EGR valve, another main vacuum hose, or a blown caput or intake manifold gasket.

9. Carburetor

If yous have an old vehicle model with a carburetor, double-check that the fuel level is properly adjusted. If the carburetor is flooded, you'll probably perceive a potent fuel odor under the hood. A little trick yous can apply is to fully depress the accelerator and endeavour to start the engine. If the engine doesn't start, await for a few minutes and attempt over again.

When your engine cranks simply fails to start, it tin be difficult to fix if you lot don't know where to brainstorm troubleshooting. This guide not only tells you where to start but helps you build your diagnostic strategy. And reminds y'all of some simple but piece of cake to forget places to look into. And so most of the time, using just this guide you'll be able to nada in on the problem.

Question: My 2000 Chevy suburban 1500 was working fine today, but subsequently in the mean solar day I tried turning on the motorcar and it only cranked without starting. The lights, radio, wipers etc. work fine but the car won't start. I've even tried jumping the bombardment automobile simply withal won't beginning, just crank. Any advice on that?

Answer: The most common on a crank-nostart condition are the ignition and fuel systems. Brand sure you got practiced spark and check for fuel force per unit area. You may try spraying starting fluid in the throttle while cranking. If it sounds like the engine wants to grab, probably the fuel organization is at fault.

Question: My 2002 Honda Accord cranks but won't outset, and I've already replaced the fuel pump, spark plugs and wires, distributor cap and rotor. And the starter has as well been replaced. Any ideas?

Answer: Make sure yous are getting a good spark. Try spraying a chip of starting fluid through the throttle plate and crank the engine. If it seems like the engine wants to catch, the problem is in the fuel organization. Replace the fuel filter, if necessary. Check for fuel pressure. The problem could exist the fuel pressure regulator or a worn pump.

Question: I'm using a Toyota Brevis 1JZ engine. Information technology'south been diagnosed several times, and it was reporting throttle motor malfunction. I inverse the throttle torso. It starts one time and and so fails then it keeps on cranking. You change the throttle body, it repeats the aforementioned process. The spark and compression is there. What could exist the trouble?

Respond: Check the electrical connectors for the throttle command system. Another possibility is a problem with the throttle command arrangement actuator, or the harness (open or curt).

Question: Why does my Chevy Utility Bakkie backfire when trying to start?

Reply: Bank check the ignition system and ignition timing.

Question: I have a 2000 Honda Civic that cranks but sometimes doesn't start. It starts afterwards xxx minutes or won't offset afterwards several hours. It also shut-off while I was driving, I changed the spark plugs and the battery is not dead. Also checked and there is fuel going into the cylinders and didn't seem to discover and whatsoever blown fuses. Any thoughts?

Reply: The trouble could be in the fuel system but it can be hard to diagnose if it is intermittent. You may have a leaking fuel injector.

Also, there could be a bad ground or loose wire that is causing too much resistance in the circuit, preventing the engine to start until information technology cools. These other posts may help.

Question: I accept a 1998 Chevy 1998 K2500 4x4 truck. I've replaced plugs, plug wires, distributor and new battery, fuel filters, fresh fuel. Fuel pressure checks out. Engine cranks just won't start until the whine of fuel pump slightly changes tone. Then it will start on next attempt. Practice yous retrieve its the fuel pump, even though pressure level checks out OK?

Answer: Spray some starting fluid in the throttle body and try starting the engine. If it catches for a second or ii, then there could be a problem with the fuel pump.

Question: My 2006 Honda Accord has a hard time starting. I have to really press on the gas hard to get it to offset. What could be the problem?

Answer: There could be a problem in the fuel organization; check for fuel pressure level when trying to start. You may take good spark if you're able to run the machine in one case it starts, just the pump may be weak or worn as well.

Question: I accept a 1995 BMW 740 that wont start. If I put starting fluid in the intake, it tries to showtime. If I bypass fuel relay, information technology comes on, but non with key. It cranks but will not start. What could exist the problem?

Reply: Make sure you don't have a clogged fuel filter first. This will forbid fuel from reaching the injectors. Then, check if the fuel pump kicks in when yous plough the primal On. Remove the central completely and so insert the fundamental and turn it On. Yous should hither the pump coming 'alive'. If not, try using another relay, or remove the relay and test it. If the pump isn't working, bank check if you have any fuel pressure. At that place could exist a leaking fuel pressure regulator or a worn, weak pump. You can check fuel force per unit area through the test (Schrader) valve. These other posts may help:

Question: I have a 98 Chevy Blazer. I have a new battery, new plugs, new wires, new fuel filter and it nonetheless won't get-go when it's cold. Once it runs, then it's good. But after well-nigh 8 hours, information technology is actually hard to start again. Why would my Chevy Blazer have trouble starting?

Answer: Yous may want to cheque the starter circuit voltage driblet. Likewise, the starter may already have some wear, making information technology harder to crank the engine. This post might help you:

Also, keep in mind that when cold, the fuel doesn't evaporate as hands, and the oil tends to be thicker. This makes information technology harder to start the engine. And, an onetime engine won't have as proficient compression as a newer model, which compounds the trouble.

Question: I have a 1999 Nissan Primera model. I went and done the motorcar and information technology could not start. A mechanic checked and realized that water had entered the ECU. I bought a new i, programmed it, and had it installed. The car could still not first. They removed the spark plugs and the cylinders were flooded with petrol. What could be the possible cause of this?

Answer: Brand sure the ignition system is producing a good spark; otherwise the computer is injecting fuel that is not getting burned. As well, there could be a problem with the injection organisation. If you didn't experience this problem prior to replacing the computer, check these two systems starting time.

Question: I have a 2003 Chrysler Town and Country that volition creepo but it won't turn over. I have already changed out the battery and fuel pump. How tin I diagnose the problem with my Chrysler?

Respond: Make certain y'all take good spark and good fuel pressure when cranking. If both check out OK, examination the compression.

Question: My 1995 GMC Yukon won't starting time later on I rebuilt the TBI. Could it be flooded?

Reply: Cheque the fuel injectors are working. Double check that the TBI was properly torqued when installed and a new gasket, if necessary. This could be a faulty fuel arrangement or a vacuum leak. Other possibilities are problems with the throttle position sensor (TPS) and IAC (idle air controller.). You can test the TPS using a digital multimeter:

Examination the IAC using directly battery voltage, and have a look at the ports for buildup.

Question: I take a 1992 Subaru Legacy wagon, and my vehicle cranks over just won't offset. I've replaced the temp sensor, crank sensor, fuel pump and strainer, coil, spark plugs, and battery. Still, it won't start. I've checked compression and fuel. Everything checks out. What could information technology be?

Answer: Brand certain to check for problem codes using a code reader. If engine pinch and fuel pressure and volume bank check out, exam the spark using an adjustable spark plug tester. Minimum, you should get around 30K V. Check the specs for your model in the vehicle repair manual.

Question: I have a 2014 Ford F150. The car cranks simply won't starting time. I tin can disconnect the bombardment cable and reconnect and information technology will start, but might non next time. Whatsoever ideas what the problem might exist?

Answer: At that place could be a problem with the engine or starting system grounds. Maybe these other posts will help:

Question: I have a 2004 Ford Ranger Edge that cranks fine every morning, only after I drive it to piece of work and information technology sits for a few hours, I take to creepo information technology at to the lowest degree twice before it volition start upwardly. What could be the problem?

Answer: The engine coolant temperature sensor may be declining, non sending the right point when the engine is warmer. Just, this tin also be a problem with fuel pressure or a leaking injector. Step on the gas when cranking the engine. if it starts you may have a leaking injector or force per unit area regulator. Otherwise, try some starting fluid. If it helps, the trouble could exist with the pressure regulator.

Question: Have a 350 Chevy, all ready to start, simply gas isn't getting to the plugs. What tin be the problem?

Answer: Cheque for fuel pressure. A bad regulator or some other fault in the arrangement tin can prevent fuel from reaching the engine.

Question: I accept a 1991 Nissan 300zx. It close off while I was driving, and it won't start. Information technology was leaking h2o beforehand. I fabricated frequent stops to refill it, only information technology cutting off and now that it's back information technology will not plough over. It doesn't leak anything until I crank it, and it'southward the fuel I believe, but information technology'southward black in color. I have no idea what it could exist. What should I do?

Answer: From your description, there might be an oil leak. Check the oil level. You need to locate the source of the leak. Take a look under the motorcar and encounter if you tin see traces of the leak around the oil pan or engine.

Question: My Toyota 1KD engine cranks simply it can't start. What could be the problem?

Answer: Follow the steps in the beginning section in the mail service to get an idea what organization is causing the problem showtime (ignition, fuel, compression). Then have it from there.
