Thanks
Has anyone ever had problems with there fuel gauge? mine is always way past full. Ive checked all the fuses im getting power to the fuel gauge but the actual gauge stays right where it is. I haven't traced the wiring yet but Im just wondering if anyone has ever had this problem?
The float could be stuck, but it's unlikely IMO. You likely have a short to ground in the sender harness, which would peg the gauge. As the float rises in the full tank, resistance in the sender decreases and causes the gauge needle to drift toward full. A short to ground would make the needle peg, because at that point there would be no resistance in the circuit at all. Go in the trunk and pull the fuel pump access cover. Test the harness accordingly.
Fuel gauge unit resistance:
Point F 3 ohms +/- 2
Point E 110 ohms +/- 7
