The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

    Fuel pump failed, left me stranded in an intersection. Diagnosis showed zero pressure at fuel pressure test port on intake manifold. Replaced fuel pump and fuel filter and everything works fine.

    Possible early warning symptom: the pump made an audible noise while running for about 10 seconds when the ignition was turned on prior to starting the engine. It continued to make this same noise after it failed, so I thought it was running and didn't realize I had no pressure. The new pump is nearly inaudible when running. Suggestion: if the pump is running noisy (I realize this is subjective) it might be a good idea to replace a pump with high mileage before it fails completely. The pumps are about $150 from GM, less than half that elsewhere. You have to drop the tank to replace it.
