Fuel gauge and temp gauge

Have you checked for voltage to the fuel level and temp sensors?

The temp sensor should be easy enough to find. The fuel level temp sensor [should] be (I have no way to confirm this from here) yellow with a white stripe. See if you have power.

The signal wires for both, should be right around 5 volts.

The signal wire(s) for the ECT should be LG/R and GY/R. One feeds the gauge and the other the EEC. You will have to confirm these wire colors.

The wire feeding your fuel level sender should be Yellow with a White stripe (YE/WH).




If you have power to both senders then test the gauges next. If not, check fuses, wiring, and grounds.

All of this would be tested with the ignition in the [On] position.
