I'm a bit stumped here.

The injectors quit pulsing when the engine gets the least bit warm. After 2 minutes at idle.

I have 46lbs of fuel pressure. (fuel pump is running)

I have spark at the plug wires, and the car will briefly start/run off of starter fluid, but dies as soon as I stop spraying.

I swapped in a good ecm, and the problem is exactly the same.

Any suggestions?

Anybody on here or did I just waste my money?


Oh and there are no error codes in the computer, other than 12 which just says it's in diagnostic mode.

There were no codes in the old computer either.

Do you have power on the pink wires at the injector connectors?. You should have 12 volts key on at the injectors, and the ECM is controlling ground. If you don't have power, check the ECM fuse.

Ecm fuse is good, and problem is intermittent.
(engine will start for a few minutes if left alone for a few hours, although the length of time it will continue to run seems to be getting shorter and shorter)

I'll check for power on the pink wire and report back. hough.
