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.

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.
