cylinder filling with fuel
This is a 97 with the 2.2L engine. What would cause the #4 cylinder to fill with fuel???
Mechanic not sure what to do and my pockets aren't deep enough for him to keep experimenting. Changed the fuel regulator, and the injector and no improvement. Next thought about trying a used fuel rail but in 97 it sounds like this is incorporated into the intake manifold. If you have any ideas, I'd love to hear them...thanks

Re: cylinder filling with fuel
Have you checked to makes sure that Cylinder is getting spark. I am not sure if it would fill the cylinder with fuel but seems logical if it does not burn it, it cannot exhaust a sprayed liquid out of the top of the head that easily. Never had that happen so kinda grabbing at straws.. Hope it helps.
Good luck. Let us know what fixed it when you figure it out.

Re: cylinder filling with fuel
KISS: Have you checked that sparkplug or tried replacing it? A cheap thing to try. then swap two of the injectors if that doesn't work and see if another cyl fills up.

Re: cylinder filling with fuel
Just replaced motor in a Sunfire and have the same problem, all four cylinders just fill up with fuel as soon as you hook up the battery. Did anyone figure out what causes this? Any help would be greatly appreciated.

Re: cylinder filling with fuel
Obviously the injectors are being held open confrim this with a noid lite if it stays on when turning the key on that is the issue, why is next. Check for a pinched wire from the injector harness for starters.

Re: cylinder filling with fuel
the injectors are hold open and fuel pump keeps on pumping, with the key on the off position. the only way to stop the fuel is to disconnect the battery cable
