need serious help
for the last month i have been trying to fix my car..one night i reved it up to about 8grand nd since then the car sounds like crap..i sent my head out to get looked out..compression test..new dis...new wires nd plugs..all new gaskets..everything checked out fine excpet my car still sounds like crap nd gas is comming out of the header..help me!!!!!
IIRC someone posed to you in another thread that it could be a stuck open fuel injector.
If you don't have an extra set just sitting around, try to determine which exhaust port the gas is coming from, and swap that cylinder's injector with another cylinder's. See if the problem follows.
I've never seen this happen before, but thought I'd throw out a suggestion since your other troubleshooting apparently has checked out.

Okay, cylinder #1. You did what already? Are you saying you've swapped around the fuel injectors? If so, did gas seep out a different cylinder's exhaust port? You need to be as specific as possible.

New o-rings its coming out of the header on cylinder 1. if the relay was bad shouldnt it not get fuel at all? and its spitting out alot sitsh injectors and still coming out. could it be ecu or wire harness
With a multi-meter and per HELMS specs, check the RESISTANCE between the two pins on all four injectors. They should be within the specs and all should be relatively close in numbers to one-another.
After that, check the voltage of the injector clips. The should all be consistant. Trace the injector clips back visually and look closely for any abrassions.
I doubt that it's your ECU. Has the wiring harness been modified in any way?
Where the injector O rings seat into the intake manifold, did you check to see if there were any foreign objects obstructing a good fitment?

I'd pull the injector clip off that one injector, and see if fuel stops spitting out.
With the car off, you could measure resistance to ground on both wires (neither of them should have a solid ground?). One is 12V, and shouldn't be connected to anything with the car off. The other is pulled to ground by the ECU to fire the injector. So, if the ECU wire is shorted to ground permanently somewhere, that'd cause the injector to stay on.

English ************!
Yeah, it could be be the ECU or wire harness. For a fuel injector to continue to spray, even if you switched it out with another injector, then the signal line from the ECU is getting shorted to ground somewhere. Either part of the wiring harness or in the ECU itself.
