Odds are, your tank sensor itself is not working properly. I recently had that problem myself. If you don't have much fuel in the tank, move everything out of the way, drop the tank, and on top, you'll see an oval-ish spot on the top with 2 wires and 2 hoses running to it. Unscrew it and pull it out. On it will be a little galvanized steel plate. bend the ears on it to remove it. There will be a metal arm that rubs against a bunch of copper coils. You can either try to bend just the arm, so it rubs against the coils again.... Or just bend the housing a tiny bit so it does the same. Then, stick the cover plate back on, screw the assembly back in the tank, and re-install it.
i have a 1990 ford ranger and my fule gauge always reads full, why?
Drain the fule tank. Plug on bottome of tank. Lift matting over tank. There is a plate hold the fule tank in place. Remove from top of fule tank.
the gauge that you need to fix is on the elec. fule pump that is inside of the gas tankyou will need to drop your gas tank to get to the fule pump. ....when you get the pump out you will see a wire float attachment on the side of the elec. pump. ....you need to bind the attachment either up or down so that it changes the position of the float ball that's there ....that will change the position of your gauge also .....good luck .....try to drop your tank when theres not much gas in the tank .....it will make it a lot eaiser to deal with getting it back up and bolted back on
Look for a bad grounding wire. If the fule gauge sending unti is properly gounded, it should send the signal to the fuel gauge, make sure the fuel gauge is grounded. You may have a bad fuel gauge.
Any Fule Kno That was created on 1998-06-02.
what i would say is follow all of the fule lines and make shoure they are not rusted on older comaros the fule lines run along the bottom of the frame so when it rains water drips off of the frame on to the fule lines which will causes rust or check the fule relay
bad fuel pump it could also mean that the fule ammount sencor is out.good luck.
Relay
The issue is most likely the sending unit in the tank, nowadays they are attached to the fule pump assembly, look there first, the gauge itself being the issue is a lot more rare.
It could be the fule pump or the wiring harness for the fule pump.
what kind of fule pump is in a 1992 ford tempo
The fule line is usually a pair of tubes that runs up the drivers side frame rails from the fule tanks to the engine compartment. the lines run up the fire wall to the fule injection rails. If this truck is Carb the fule line should be in approximately the same place.
