Question about 2006 Nissan Pathfinder
What controls gas flow
Posted by Anonymous on
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.

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.
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!

your pick up coil or parts inside the distributor have failed you may have to check and replace some parts or maybe your whole distributor. sorry.

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.

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!
