Why Won’t My Car Start?
When your locomotive cranks but wo n’t start or run, it could mean your engine is having trouble producing a discharge, getting fuel, or creating compression. The most park causes are problems in the ignition ( for exercise, a bad ignition coil ) or fuel organization ( for example, a clogged fuel filter ). however, the source may besides be a mechanical fault ( for model, a leaking valve ), or defective components in early systems. What “ crank-no-start ” does n’t by and large mean is a problem with the starter. If the engine cranks normally, you do n’t have a startle problem.

Your car engine needs fuel, compression, and a spark to start. Photo courtesy of Sfoskett on Wikimedia If it is n’t cranking mighty ( the engine rotates slowly or does n’t rotate, or you hear wyrd noises or nothing when you try to start the engine ), check this other practical steer to troubleshooting the begin system. Whatever you do, avoid cranking the locomotive repeatedly with the hope that the engine will fire up. You may drain your battery of power and damage the starter centrifugal in the work. rather, try to use the commission left in your barrage to locate the fault. In this article, I offer the follow :
- Quick Diagnostic Tests
- Do You Have Spark?
- Is Fuel Reaching the Cylinders?
- Do You Have Proper Compression?
- Other Possible Components That May Cause a No-Start Condition
This guide will first base give you six flying things you can check, and then three systems to troubleshoot—the trip, the fuel, the compression—using some simple and agile diagnostics. then, for more help oneself, you ‘ll see a list of components in relate systems that can be associated with a no-start condition . Scanning your car computer memory should be one of your first diagnostic procedures. Photo courtesy of Robert Couse-Baker on Flickr
1. Six Quick Checks (Check These First)
When trying to find out why your car does n’t want to start, keep in mind these possibilities .
For model, make indisputable there ‘s actually fuel in the cooler .
Scan the Computer Memory
The computer in modern vehicles monitors and controls a good number of sensors and actuators. Scan your computer memory for trouble codes before you do anything else. tied if the check engine light has n’t come on, you may find a pending code that can guide you in your diagnosis. false stimulation or lack of input signal from sensors like the crankshaft position detector ( CKP ) or camshaft situation detector ( CPS ) can prevent the engine from starting. besides, a regretful strangle position detector ( TPS ) may cut off the spark to the cylinders .
If the engine cranks lento, you may be dealing with a drop battery, loosen or corrode battery terminals, or starting system wires
Problems with the crank centrifugal or tour can prevent the engine from starting. You may want to check the circuit electric potential dangle or have the appetizer centrifugal checked. Pay extra care to unusual make noise when crank .
many modern vehicles come equipped with an engine immobilizer as an anti-theft security system. The car ‘s security system may have made an erroneousness that disabled the fuel or ignition system or the chip in the key may have failed. To troubleshoot a built-in security system organization, consult your cable car owner ‘s manual or consult with the workshop that installed your dismay organization .

2. Do You Have Spark?
first, you want to check that a dear discharge is reaching the cylinders. You can do this screen without a flicker tester, but it ‘s better to use one because a weak spark a well as a missing spark can prevent your engine from starting. If possible, use an adjustable tester so that you can test for 40KV, 30KV, and 10KV spark .
- Select an easy-to-reach spark plug and unplug the spark plug wire, or coil wire, or coil on plug (COP).
- Set the spark tester to 40KV, and plug it in at the end of the spark plug wire or coil wire. Hook the spark tester to engine ground. To ground the tester, use 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 ground (engine block, bracket, cylinder head). You still need a helper to crank the engine for you. The rest of the test is the same. You’ll be able to test for the presence of spark but not its strength.
- While watching the spark tester, have an assistant crank the engine.
- You should see a bright spark jumping the gap in the spark tester.
If you do n’t see a discharge, repeat the test. This time, adjust the spark tester to 30KV. If you still do n’t see a discharge, repeat the test and set the examiner to 10KV. If this clock you see a spark or no spark, you have a problem with the ignition arrangement. Consult your fomite repair manual for your especial model for far diagnosis. Depending on your particular model, you may have a trouble with an ignition coil, distributor, ignition module, lighter, or some other related part .
Other Spark Checks You Should Do
- On systems with a distributor: Check that the distributor cap isn’t loose; inspect the distributor cap for moisture, cracks, carbon traces, or some other damage; 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.
- Also, check your car owner’s manual or vehicle repair manual for the interval schedule for the spark plugs. You may need to service (gap check and adjustment) or replace the plugs.
- If you installed new spark plugs and your car refused to start right after, double-check that you installed the correct plugs for your vehicle model, and the plugs have the correct gap. Use a wire feeler gauge to check and adjust the gap.

3. Is Fuel Reaching the Cylinders?
After checking for sparkle, you need to check that the locomotive is getting fuel .
How to Check a Carburetor or Throttle Body Injection (TBI) System
- Take the lid off the air filter box and open the throttle plate (carburetor). On TBI systems, watch the fuel injector.
- Ask an assistant to crank the engine and see if fuel is being fed into the unit.
- If you don’t see fuel being injected, your problem is in the fuel system. Make sure of the following:
- you have enough fuel in the tank,
- the fuel pump is working,
- the fuel filter is not clogged (consult your car owner’s manual or repair manual for the service schedule),
- the fuel pressure regulator is working properly
- the fuel injectors are not clogged.
How to Check a Multiport Fuel Injection System
- First, make sure the fuel pump is working. Momentarily remove the fuel filler cap.
- Ask an assistant to turn the ignition key to the On position, but don’t start the engine.
- As your assistant turns the key, listen closely through the filler neck of the fuel tank. You should hear the whirring sound of the fuel pump motor being energized for two or three seconds. If you hear the sound, at least you know the pump is getting power; continue with the next step. Otherwise, you may be dealing with a faulty fuel pump or relay, a blown 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 problems 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 similar to the one on your tires), use a small screwdriver to press on the valve. Be ready with a shop rag to catch the fuel.
- Turn the ignition key to the On position for two or three seconds and then turn it off. Repeat the step two more times to prime the line with fuel.
- Then, 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, then 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 gauge to the test fitting valve and turn the ignition key to the On position and read the gauge. Then have an assistant crank the engine and read the gauge.
- Compare your gauge readings to the pressure specification listed in your vehicle repair manual.
- If the pressure is lower than specification, your problem lies in the fuel system, possibly a faulty fuel pump, clogging fuel filter, or bad fuel pressure regulator. Detach the vacuum hose from the top of the fuel pressure regulator. If the line is wet and smells like fuel, replace the fuel pressure regulator.
- If the pressure is within specifications, you can unplug a fuel injector electrical connector and plug in a nod light to the harness connector (you may loan a set of nod lights from your local auto parts store).
- Ask your assistant to crank the engine, while you watch the nod light.
- If the nod light flashes while the engine is being cranked, you can at least assume that the injectors are receiving the pulse signal from the computer. If not, you need to check for a blown fuse or bad relay in the fuel injection system, a problem 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 list of related components below.
Some Cars Automatically Shut off the Fuel Pump After a Crash
Some models, like many Ford vehicles, have a fuel pump trade ( inertia switch over ), that mechanically cuts ability to the fuel pump when involved in an accident. If your engine refused to start after an accident or after a vehicle come to yours in a parking lot, check for an inactiveness switch. The switch helps prevent your car from catching on arouse if an accident happen. Check your car owner ‘s manual or fomite repair manual to locate the substitution. You can pop the clitoris back in manually . A botch head gasket can lower engine compression enough to prevent the locomotive from starting. Photo courtesy of Tony Harrison on Flickr
4. Do You Have Proper Compression?
compression in the cylinder heats up the air-fuel mix and helps the sparkle ignite the mixture so the burning takes home. During the burning serve, though, there should be no air leak. differently, the cylinder will have poor people combustion, or it will not happen.
The most common source of air ( burning ) leak is a jump clock belt or chain that allows tune to escape through a valve ; it can besides happen because of a burn valve, exhausted compaction rings, or a blow head gasket.
A clock knock or chain synchronizes the camshaft to crankshaft rotation. After miles of servicing, it wears down, becomes damaged, or breaks. so car manufacturers suggest replacing a time knock every five years. A clock chain may have a wide service agenda interval. Replacing the swath or chain at the indicate interval can prevent serious locomotive mechanical problems. Consult your vehicle repair manual.
On some vehicle models, it is easy to remove the time cover to check if the belt or chain is calm in stead. If it is, you may be able to visually inspect the belt or range condition, and then check that it has n’t jumped. Follow the instructions in your vehicle repair manual of arms.
Likewise, you can check compaction blackmail using a compaction gauge. If you have a gasoline locomotive, you screw the gauge into a spark plug fix ; on diesel engines, screw the bore in place of a glow plug or injector beak. Follow the instructions in your vehicle repair manual.
Gasoline engine compression ranges from 130 to 180 pounds per feather column inch ( psi ) ; diesel engine compression may range from 250 to 400 psi . A fail EGR valve can prevent your engine from starting. Photo courtesy of Moosealope on Flickr
5. Other Components That May Cause a No-Start Condition
Faults in other systems, not good ignition, fuel, or compression problems, can prevent your engine from starting. A system component itself may be faulty, or there may be a problem with its telegram connection or harness. You may need to expand your diagnostic operation to the components below.
Computers in modern vehicles monitor many of these components ( normally in emission-related systems ) and can set trouble codes when problems arise. so do n’t forget to scan your computer .
The consume boast recirculation ( EGR ) valve introduces a mensural sum of exhaust gases into the intake manifold to get re-burned. This helps lower engine temperature and harmful emissions. But the valve can fail and stick either open or closed. When the valve sticks unfold it may prevent your engine from starting. other symptoms of a stuck-open EGR valve include roughly idle and stall .
2. Cold Injector
Some vehicle models use a cold-start injector. It operates as a regular injector, but merely works when the engine is cold. The injector may have its own thermo switch or may be commanded by the system restraint module. If either the switch or the computer lap fails, you may have a hard clock time starting the engine during cold months. Consult your vehicle compensate manual, if necessary .
The multiply absolute imperativeness ( MAP ) detector compares the barometric ( atmospheric ) press to the inhalation multiply vacuum. When the detector fails, it can prevent your engine from starting. not all vehicles use this detector. Consult your vehicle repair manual .
The mass airflow ( MAF ) detector tells the computer the sum ( the concentration ) of the air entering the engine. A park MAF trouble is a soil or foreign matter blocking the sense element, preventing the detector from working. Or the detector itself may fail after miles of service. You can clean and test the detector at home .
The computer uses the engine coolant temperature ( ECT ) detector to know how much fuel the locomotive needs and when to enter close loop topology operation ( that is, when the engine has reached operating temperature ). Depending on your especial model, a bad ECT detector can upset ignition time or the operation of the infection or cooling fan. Consult your vehicle compensate manual, if necessary .
6. Canister Vent Valve
The case shot vent valve is part of the evaporative emissions dominance ( EVAP ) system. The EVAP system temporarily stores harmful fuel vapors into a canister to prevent their let go of into the standard atmosphere. When conditions are appropriate, the computer routes the fuel vapors out of the canister through a canister vent valve and into the inhalation manifold for cauterize. A faulty valve, though, can prevent the engine from starting. Consult your vehicle animate manual for the routine to test the valve .
The accelerator position detector ( TPS ) monitors the position of the accelerator valve. It sends a electric potential signal to the computer. The calculator uses this information to regulate the air-fuel mixture according to locomotive needs. On some vehicle models, a exhausted, failing or bad TPS will prevent your engine from starting at all .
8. Vacuum Leaks
Vacuum leaks are not uncommon, and they are the source of many engine performance problems, including failure to start. Depending on where the fault is located, vacuum leaks can be hard to find. But major vacuum leaks that can make the engine difficult to start may happen in the power booster vacuum hosiery, EGR valve, another main vacuum hose, or a waste head or intake manifold paper gasket .
If you have an previous vehicle model with a carburetor, double-check that the fuel level is properly adjusted. If the carburetor is flooded, you ‘ll probably perceive a impregnable fuel olfactory property under the hood. A small antic you can use is to fully depress the accelerator and try to start the engine. If the engine does n’t start, expect for a few minutes and try again. When your engine cranks but fails to start, it can be unmanageable to fix if you do n’t know where to begin troubleshooting. This template not merely tells you where to start but helps you build your diagnostic strategy. And reminds you of some bare but easy to forget places to look into. So most of the time, using just this template you ‘ll be able to zero in on the problem. This article is accurate and true to the best of the generator ’ second cognition.
