Where is fuse for fuel gauge located and what is it's name for 2003 Pontiac grand prix
Try fuse #32 in the underhood fuse box. It's marked "fuel pump". HTH. -Jim
BTW if your gauge always reads empty, it's a bad ground. HTH. -Jim
It only goes to empty if I'm on a incline. Other than that, it stays full.
So does this mean it's still a bad ground? And how hard to fix this?
No, then that's a bad power (+) wire. Most likely the problem is the plug or wiring back near the fuel pump. The sending unit for the dash gauge is part of the fuel pump assembly. HTH. -Jim
So where is this plug located? Maybe I can unplug it and clean it?
Under the car. Back near the gas tank. HTH. -Jim
Thanks for everything Jim your an amazing help
So it wouldn't be in the trunk on this make and model I'm guessing?
That would be too easy. No, its underneath the car.
Maybe easy for you, but I have never worked on a car.
No, unfortunately it's under the car. HTH. -Jim
