Symptoms were intermittent stalling while driving and failure to start when the engine was warm. The fuel pump and PMD was replaced with a GM factory replacement purchased from a GM dealer. One week before the (one year) warranty on the replacement pump/pmd expired, the new pump began showing the same symptoms. (By the way, GM refused to honor their warranty.) The PMD was replaced and the failure to start symptoms were corrected, but the engine would still hesitate, stall, and had slow acceleration along with no power on hillsides, necessitating replacement of the fuel pump.
Vehicle wouldnt start. I could hear the starter working looks like the fuel is not being fed to the engine. Towing to the dealer, looks like a fuel pump failure.
At 55,000, the van stalled and was loosing power to the engine. Had it checked by the dealer, replaced chip/kit.
just bought this vehicle with 187k, had mechanic do full diagnostic, no fuel pump problem drove 30 miles changed all tires no problem, left there no fuel pump problem, stopped to discuss next day agenda with vehicle off. Vehicle would not turn over, we had to push into park spot behind supermarket for the night.
