1991 gmc sierra sat for 6 years and won't start

SOURCE: i need help resetting my 94 GMC seirra's gas gage

the gas gauge is on the fuel pump assembly with in the fuel tank, you must have bumped it during reassembly. the only solution is removal. pull it out check for alignment and binding, reassemble being very careful. hope this helps.

SOURCE: Have a 1995 GMC Sierra Truck. Gas is leaking from

chances are your leaking from the gas line from your fuel tank to engine. More than likely the pressure line, but it could be your return line as well. To figure this out you would need to take your fuel tank off the vehicle, and inspect the lines. look for rust and cracks. Rust is a good sign of weakness, and chances are this is where your leak is. Hopefully this helps.

When your replaced the pump did you replace the fuel filter? You may have a fuel pump relay causing you some grief. I believe it is located in the engine compartment in the fuse center on the left inner fender. Check the relay and any related fuses. Check the electrical connection at the pump. They had problems with some of them and they would get kind of hot and distort and corrode. They have new updated ones that can be easily installed.
