Igniter maybe bad, which is that unit on top or underneath your coil. Or maybe the ignition pick-up coil inside the distributor. In my experience I have run into more IGNITER problems.

Mitsubishi endeavor 2004 coil pack burnt out changed and turns over but no start spark plugs wet from fuel but not starting


There are so many possibilities, fuse, command module, crank signal? Is the module getting 12 volts. It is rarely a whole ignition coil pack goes out unless of a short. Was the unit burned up? If not, it could have a bad crank position signal. The cam sensor is mainly for fuel and crank sensor is mainly for spark.

My Mazda 1989 just cut out when I accelerated , it turns over but doesn't start the fuels still going to the carburetor but the engines not starting


check that the distributor is turning over.(broken timing chain). Check that the coil lead is still firmly in the distributor cap and coil . check that the coil is getting power from the ignition switch check in the distributor cap for carbon dust that is shorting out the spark

While driving audi a4 died an not starting


- Won't start
- Check for spark (no spark on any cylinder)
- Check for rpm signal to ECU with scan tool or vag-com (checks good)
- Check for power and ground at coil packs (no power on red/green wire)
- Check fuse 29 (fuse checks good, but is not energized during cranking)
- Check ECM power relay (is getting power and ground to coil side, and power to source pin. It clicks, but no output to load pin)
- Jump relay (vehicle runs)
- Replace relay.

Mgb problems


The only way the engine would keep running smoothly (not engine pre-ignition running) is that the coil is still getting power. If you look at the coil you will see the supply side of the coil comes from the start switch. There is where you should "start" checking. I recommend you also check the start relay for sticking. Something in the starting circuit is not cutting off the voltage to the coil...allowing power to the distributor points.

Coil cap


Will it try to start if you use starting fluid ?
Are the injectors getting power and a ground signal from the computer ?

CRANKS BUT WON'T START


Your car may have set a problem Code and a scanner will identify it. Since you have all dashlights on during the cranking phase, you just don't see it until the engine would start.

What you can try is a little starting fluid. If the motor tries to start or runs briefly, you have found that you have a fuel problem and the engine is firing. There is a test tap on the fuelrail for fuelpump pressure. If you have no pressure it indicates the fuelpump is not working and you need to find out if it is getting power. Also, if there is fuel pressure, you need to find out if the injectors are working.

The autoparts stores have loaner programs for the injector bulbs and the fuelpressure meter. Each area can be tested to see why you are not getting gas into the engine.

Should you not get results from the starting fluid, you will need to look at the spark system. If the starting fluid does nothing, then you probably have no spark. There are ignition Relays which provide power to the coil and crankshaft sensors which tell the spark to go to a particular cylinder. If you do not have power going through the coil, it may be bad or not receiving power from the ignition or crankshaft sensor.

Autozone.com has free wiring diagrams and fusebox diagrams available online when you register your car on its site. If you suspect a bad coil, it can be hand carried and bench checked.

Last week her trooper just died,wouldn't startt.We changed the fuel pump it ran for a week again it won't start.


Did you check the fuel pressure before all of this fuel pump replacement? If the fuel filter is old enough to be clogged up, it should have been changed long before replacing a fuel pump unit. Your fuel filter should be changed every 30,000 miles. However, it would have to be TOTALLY clogged up to keep the engine from starting. It would have been causing all kinds of drivability problems LONG before that could happen.

Then, has anybody bothered to check for spark when the engine will not start? Has anyone scanned the onboard computer? (which happens to be in full control of both the fuel system and the ignition system)

You just might be trying to repair the wrong system...

There is no way anyone online can accurately tell you why it will not run without checking the vehicle first....although many uneducated DIYers might GUESS for you...which seems to be just as good as you are already doing....

PROPER DIAGNOSIS REQUIRED!

The 1992 Caprice I'm working on has no Spark to the Coil I've changed the coil and the electronic spark control module. What else besides the Fuel pump or something else could cause the problem of no start...


You say no spark to the coil. does that mean that you have checked the power to the coil & getting none or are you getting no spark from the coil to the distributer cap? If you have no spark that is most likely the problem of not starting but you can always just check your fuel pressure to see.
