Electrical problem
1993 Chevy Lumina 6 cyl Front Wheel Drive Automatic
Question: 1990 Chevy Lumina euro 3.1 mileage: 140,000. I am completely stumped. I have read all of the questions posted and my problem is not in them. When my car gets warm the engine shuts off and will not start until it sets and cools for about an hour. I have changed all of the following; crank sensor, coil packs, ignition mod, knock sensor, engine temp sensor, fuel filter, O2 sensor, computer. The car runs beautifully until it gets warm. I have tested fuel pressure and it is 38-41 psi before, during, and after the engine stops. I hooked up a noid light to the injector, I am losing injector pulse I'm not sure why. Could you please give me some info on what to try now?
Answer: Considering all that you have already replaced, it is our bet that you either have a faulty power relay for the computer or the ignition switch is bad.

Ok where is this power relay for the computer located at.Its not in the fuse box under the hood on the passenger side nor the driver side.My friend in having the same problem.Redy to take a sledge hammer to it.
