I have just replaced a bad fuel pump in a 1997 GMC Yukon and while the old pump did nothing at key start or during test the new pump cycles when tested but will not cycle to prime with the key in the on position nor will it run when the engine is cranked. What could it be? I already changed the relay and have found no bad fuses.
have the same problem?
