98 gmc jimmy fuel guage not working


No issues with the fuel guage that I know of , but you can follow the basic troubleshooting guidelines. Starting with the wiring disconnect at the fuel tank for a bad connector or bad connection. Only other connection would be up to the instrument cluster in the vehicle. Only replaceable items would be the guage or the sending unit in the fuel tank. You can disconnect the return line circuit or connector at the at the gas tank and jump a wire to the ground the that feeds the gauge and see if the guage moves, but don't and i repeat don't hold to long because the guage will go over hard over and could damage the guage. If the guage moved and I would suspect a bad float on the sending unit or a bad sending unit, either case the fuel pump assy would have to come out for repairs.

It could be a few things. You can check these parts. You may have a defective voltage regulator, a lost ground in the sending unit, a bad sending unit, a break in the wire, or a defective fuel guage. The only way to test the wires is with a voltage meter. Test the current in each area and part. It has to be one of them, it is just finding it. All ground wires are black. You may have a loose wire, instead of a break. Make sure you check all your connections. If you need anything, let me know. Thank you very much for choosing FixYa.
