2003 Pontiac Grand Prix Q&A
2003 Pontiac Grand Prix Question: What could cause a fuel pump to come on when the key is turned, but no fuel?
Did you replace the entire pump module or put a new pump in the old one? You say the pump is workng but no fuel right? If you replaced just the pump itself possible hose from pump is defective, wrong pump or running backwards, out of gas, filter on pump pick up clogged, external filter blocked, just some things that come to mind. How/where are you ckecking pressure? - pushrod
