Thread: LT1 Engine stopped while running

Tweet

Wow! This has been going on for almost seven months and it's still 75 miles from home with occasional trips to work on it? Have you considered towing it home, maybe on a two wheel dolly or getting a friend with a trailer & winch?

The only other cut off switch that can cause the ignition and the fuel to shut down completely is the fuel and ignition cut off switch that are installed incase of roll overs I had one go bad on me years ago and I was baffled for weeks too.....not certain if thats what it could be...but maybe worth looking into as well.

Just a note about ECU's. My Camaro(with an LT1) has a factory engine anti theft system, I believe it's called CAGS. If your car has it, the ECU reads the chip in the your ignition key. It looks for a set resistance (as burned into the computer) through the chip, if it doesn't match, the car will not start. I only mention this because you said you were going to replace the ECU. If you do replace the computer and your car has CAGS, get the chip out of the donor car ignition key and place it in your key.

glad you got the problem solved.

the key works with the theft control modual, which also does doors, windows, power seat functions--ecu only needs signal from the tcm to run the fuel

can you tell me what pin number was corroded??and wire that was bad?

The 4 harnesses to the ECU are color coded. It was the red wire in the black black harness. I didn't check the pin number. I didn't find the break with an ohmmeter. The wire was fat with green corrosion about 4 inches from the termination to the ECU

Yes that would be somthing to right down

Glad you fixed it.
