The fuel pump pressurizes the system and circulates fuel past your fuel injectors. A fuel pressure regulator makes sure there is adequate pressure on the line for the injectors to release the proper amount of fuel when they open (rough explanation). The fuel injectors are controlled by the computer, not really the gas pedal. The computer handles everything for the fuel injection. The gas pedal just opens the throttle plate, allowing more air in. More air needs more fuel, more air and fuel = more power. It all happens very, very fast. Anyway, cranking the vehicle will result in fuel being injected into the cylinders. Without it burning off, yes it could accumulate on the spark plugs and they would appear wet. To work properly, the engine needs (basically) air, fuel, spark, and compression. The timing has to be perfect too.
Look up a quick test on the IPDM ECM relay test. You swap the relay for the computer with one for foglights and test to see if it'll start. That ECM relay has been know to rust internally and fail. Swapping with the foglight relay is merely for testing/troubleshooting purposes. If it works, then you should purchase the proper relay.
There could be many other causes, but this one is pretty easy to try.

SOURCE: crank no start ,got fuel got spark, when trying to

You pinched the fuel line????
If you crank for too long to start the car, the engine will "flood", this is why the plug was wet. It had too much gas and wouldn't start.
Pull out ALL plugs and dry them off.
Install them.
HOLD your gas pedal to the floor and crank.
This will stop gas from entering the engine.
you need to get that extra gas out beofre it will start.
If you have so much gas in there you can do damage to your engine!!
Now after a few crnaking attempts with your foot to the floor, take your foot of the gas pedal and try to start it again.
But remember if it doesn't start in 3 tries, you need to do the pedal to the floor once or twice to remove the excess gas.
When you crank the car to start it sprays gas into the engine, even if it won't start. So it very easy to "flood" the engine, and then you'll have a hard time to get it going!

SOURCE: how to check ignition coil

Most parts stores, such as Auto Zone, can give you the specific Ohms values for your coil. You will want to check the resistance between where the coil wire goes to the coil, and the electrical terminals the coil. And compare it with the OEM resistance.

SOURCE: nissan pathfinder wont start. fuel

Try drying out the spark plugs. If the car starts after that, then you might have a leaky fuel injector. In my opinion, I think they're wet only because you probably were cranking it alot trying to start the car. I would change out the CAS (crank angle sensor) and see if she runs, as the majority of "not starting" cars I worked on was due to this. Hope this helped!

Won't start but did and stalled out won't start at all now and oil filler cap smells like gas


If the oil cap smells like gas, one of the injectors may be flooding the cylinder and the crankcase. That would not be a filter problem.
Check the spark plugs to see if they are wet.

Car wont start but kicks over


Since you do have A fully charged battery and also you do receive fuel smell after crank start and the car wont start,either you do have an Ignition fault means not giving the spark,advice remove the spark plugs and check whether are wet with fuel,see whether are black,if so change them and before start check by leaving an HT lead off a spark and use one of the old ones connected to the HT lead and earthed to the engine,ask somebody to start the engine checking for any spark comes out. If yes then put the HT lead back to the new spark on the engine and try. If ther is not any spark,then you have to go backwards from the HT leads to distributor,Rotor Arm,Electronic igniter,Coil if is fitted,Fuse and relay. Good Luck.

Suzuki Aerio won't turn over


If it cranks it turns over just to clarify.
The plugs may be fuel fouled and not sparking inside the cylinders. Its possible one of the injectors is shorted to ground and making all of the injectors stay open.
I would pull the plugs and see if they are wet or dry, if wet unplug the pump relay and try another set of plugs to dry out the cylinders.
If you can get it started, try putting the pump relay back in.

2004 gmc jimmy, tried to start fired twice didnt catch now just turns over,i can here fuel pump and smell gas.replaced ignition coil??? still wont fire


Check the ECM/BAT fuse. this fuse controls the ECM and the fuel injection circuit. If the fuse is ok, you need to check for voltage at the spark plug. Pull the #1 spark plug. If the cylinder is getting fuel the plug will be wet with gasoline. Put the spark plug wire back on the plug. Now crank the starter and look for a spark from the spark plug electrode. If you can let me know what you find from these tests, I can help you determine the next course of action.

Cranks but wont start


a host of reasons,
  • check if you have a spark buy removing ht lead from spark plug and holding near metal pat of engine while cranking, use insulated tool to hold lead, if spark thats ok
  • remove spark plug after lang cranking and smell if gas is present or plug is wet, if wet you are geting fuel
  • then ask again once you know what is not happening
  • has it electronic ignition
  • has it fuel injection or carbs
