Question about 1997 Pontiac Grand Am
I just replaced a fuel pump on my 99 pontiac grand am se v6. put it all back together, now all of my instrument panel gauge's do not work, my passenger side brake light,and reverse light do not work but if i remove the trunk release fuse with car running all of the gauge's work but no brake or reverse light work. if i plug fuse back in wait 5 seconds they stop working again. i also have checked all other fuse's with no blown fuse's detected, relay's seem to be fine. i dont know if I'm grounding out some where. i really dont want to drop the gas tank again. its got to be a fuse some where i just need to located it. what is my problem
Anytime when there is multiple issues, I pick one system when the problem is ongoing, check voltage and ground.
The fuses in picture is for instrument cluster, Check for voltage at the fuses when problem is ongoing. Use a test lite. As you can see, one fuse is hot all the time, the other goes hot with the key on.

This can be your Body Computer Mod. It is located on the right side under your dash. Usually black or gray box about 6'x6'x1' with the plugs. You can by new, but used are fine too. You will need your VIN # for either. Good luck

Pull of the grey cover and right before the intake its a black thing about two inches wide with two screws and a wire harness

If you replaced the fuel pump then there is a possibility that during the job then some debris from the tank and/or filter got loose somewhere into the fuel system and is in your lines. It could even be a very tiny speck of gasket material, old or new.

Sounds like air in fuel line. Purge fuel line. By "crank", do you mean engine spins but won't catch? Try starter fluid in intake.
