Pontiac Repair: 94 grand prix, fuse boxes, fuel pump relay


Question
where is the fuse between the ignition ad the fuel pump relay, on a 1994 pontiac grand prix, fuel pump has been changed, put a brand new relay in and there is no voltage going to the fuel pump relay 3.8 engine.

Answer
Hey Taurus.

That car has multiple fuse boxes there is one on the right side of the engine compartment and one on the left. The left one is up by the strut tower that may be where the relay is and also the fuse for that relay. Usually the fuse for the fuel pump also runs the ecm/pcm so you may have other issues other than just the pump not running. Does the relay get the signal from the pcm to turn on at key on engine not running? does it get a signal when the engine is cranked over? when you say it has no voltage do you mean constant battery voltage or command from the PCM? there is a difference. hope that helps and good luck :)
