The gas gauge in my 92 Ranger never has showed anything at all, the needle never has moved. First thing I checked was the sender, pulled the bed off, and removed it, on the bench, the resistance changes smoothly from empty to full and back. So, I figure the sender is good, and inspect the wiring to it, and didn't see anything out of the ordinary. I pulled the cluster so I could swap in an exploder cluster, and checked the resistance there, and it seems to be getting signal to the cluster. I put everything back together, and figured when I got the money I would buy a sender, thinking maybe it is breaking down when the truck electrical system powers it up. Now, today something interesting happened, which makes me think it's ground related. When I turned the ignition on, without starting the engine, the gas gauge moved slowly up to between 1/2 and 3/4 tank. It dropped back to empty when I started the engine. As I pulled out onto the highway, my oil pressure gauge dropped way past the bottom L of the gauge, and the gas gauge started working again. All of a sudden, my oil pressure gauge swung up to the "High" position, and my gas gauge showed way over full. Just as suddenly, the oil pressure gauge dropped back to normal, and the gas gauge quit working again. So, I figure the cluster must have a bad ground. Now my question is, where does the cluster get it's ground from? I'm assuming the oil pressure and fuel gauge share a common ground at some point, and it's loose or corroded at it's connection to the body.
