Find the yellow wire in the trunk (I think it's always yellow) or in the front of the gas tank, or pull it carefully off the tank itself, and ground it (to clean bare metal, a shortage of that under the car!) That should make the dash fuel gauge read FULL. * If it does, then the tank sender or wiring is the problem. Or the tank is not grounded. * If it does not, then the problem is upstream of that wire -- the gauge itself? Notes on the PC board not right? * If the temperature guage does not work also, it's likely the voltrage regulator which is built into one of the gauges (some temp, some fuel, depends on car model and year).
