My fuel gauge doesnt work on my 2002 grand prix. how do i fix it?
Usually this problem originates from the sending unit, not the gauge. It's unfortunate because the sending unit is located inside the fuel tank. It's even more unfortunate because the sending unit is integrated into the fuel pump assembly, which costs ~$200. Sometimes the sending unit contacts can be cleaned / sanded, but most often, because the labor is about the same cost as a new fuel pump assembly, people opt to just replace it.
Good luck.
