Re: 91 Lumina sudden death problem

Since the car didn't start on the starting fluid, you have no spark. Checking fuel pressure is irrelevant at this point because even if the fuel pump was completely inop, the car would have started on the starting fluid.

There are three common things that would cause a sudden no-spark issue on this car.
1. Bad crank position sensor or the wiring between it and the ICM (Ignition Control Module).
2 Bad ICM (these can be tested at most auto parts stores)
3 Bad ECM (computer).
