It only shuts off when the car is in motion. When it shuts off a wierd sound comes from near the back of the car. It use to would start right back up while in neutral while it's still rolling but now I must put it in park and to restart. It doesn't start right up it takes a few minutes and few tries and the engine will turn on over and attempt to start and then after a few it will start up.
What will cause my car to just shut off while driving at an average speed? on 2000 Pontiac Grand Prix
sounds like a failing fuel pump. have it checked at a shop and get a bid.
