My fuel gauge stopped working (stuck on full at about 3 o'clock) and it made me crazy trying to find the problem. Took out the tank, grounded the pink sending unit wire and then grounded the black ground wire from the sending unit. No movement from the gauge at all. Then I took the gauge out and replaced it with a working spare I had (I did this with the instrument cluster still installed in the dash, just removed the two plastic bezels and a few screws). Still no luck. I started looking for a broken wire somewhere, but could not find one and following the wire became difficult around the brake booster. I almost gave up, but couldn't think of anything else to try. Today I was tracing wires under the dash looking for my non-working horn problem and saw the wiring harness connector on the back of the instrument cluster looked strangely positioned. I reached up and pressed on it, apparently re-seating it in it's place and WOW! the fuel gauge started working again. It must have vibrated loose at some point. The strange thing was that everything else in the instrument cluster was working, leading me to believe it was just a fuel gauge system problem. By the way, it turned out that the horn itself had acquired just enough corrosion at the bolt hole on the radiator support to corrupt the ground circuit and keep it from working. A little sandpaper at that spot and my horn started working again. I hope my experience helps someone.
