Re: gas gauge pass full
This symptom you describe says this is an open circuit in the wiring.
First you might check the connection of both the wire to the sending unit above the tank at the front. You can reach up there and/or view it with a flashlight and mirror to ensure the tan wire is attached to its terminal and the ground wire, black in color, is attached to the s/unit chassis.
You should check the connection of the black wire to the pass side tank strap mount for a clean connection. Might even use a 5/16 wrench socket to remove the screw and wire brush both the lug and ground and reattach and test gauge again. Most common problem.
if you have a multimeter, and with the ground sire disconnected, measure the black wire to ground for voltage. No voltage, open in the circuit from the back of the gauge to the sending unit. If you have voltage, the a good ground connection with the terminal to ground should cure the problem.
If no voltage, there is a connector just above the drvr side kick panel, you might have to remove the kick panel to get to it, connector has about eight wires going to it. You might unplug it and plug it together to make connections. But if rear lights works, this connector would not be your problem.
If all fails, then you might need a sending unit for the tank.
Keep track of mileage and every 150 or 200 miles, fill the tank.
