1999 Monte Carlo fuel gauge stopped working

Hi there. If the fuel gauge is the only one acting up, its probably a loose or corroded wire on top of the gas tank where the fuel pump sets in. It could also be a loose wire on the back of the gauge, which is easier to get to so you could always check that first by popping off the dash pannel and pulling out the instrument cluster and looking for a broke wire on the back of the fuel gauge. But if I had to bet I would guess its on the other end by the fuel pump. Worse case sinario, maybe a bad sending unit.
