Question about 2002 Pontiac Grand Prix
Odds are the pump is bad, but it could be the relay or wiring. Try pulling the relay out and using a different one. You could use the horn relay, for example. If the fuse blows again, take the connector off the pump and interrogate both sides with an ohmmeter. The grey and black wires go to the pump. The resistance between these should be really high on the connector and should be at least a few ohms on the tank side. Whichever side has no resistance is shorted. Am I making sense?
