    1993 GMC Sonoma, Fuel pump issues :(

    I swapped out an in tank fuel pump and am still not getting fuel. I am hoping there is a relay hidden somewhere that needs to be reset or changed. I have power going to the fuel tank sending unit. I know this because the fuel guage works, but it spikes all the way past full sometimes, even though there is only 10 gallons of gas in the tank. Thinking I crossed the wires, I swapped them and, still no fuel.

    Does anyone have any suggestions or advice on where to look for a fuel relay or what else might be causing the trouble?

    Thanks in advance. Q

    I have some of the same issues with my 96 Explorer.  Am getting power to the pump, guage reads full when only 5 gallons.  but read my post about a real electrical nightmare.  Good Luck, Mattie
