Hi, the fuel gauge on my 1993 Ford explorer xlt hasn't been working for quite some time. I bought it in late August, and the previous owner said he got the fuel pump replaced 3-4 years ago, and when he got it back the fuel gauge stopped working. I believe it has to do with the wiring in the tank because all the other gauges work fine, but I have no experience with this type of thing. If anyone has a diagram for the tank, that'd be great. I suspect it's the ground wire, but wouldn't that mean the fuel pump wouldn't work? It pumps fuel to the engine fine. Any help is greatly appreciated.
