This vehicle hass a pretty common rate of failure on the fuel level sending unit, they most generally will set a code and turn the check engine light on but i have seen quite a few that dont. With out a scan tool to see what the computer is reading to see if it is the same as the gauge to verify that the gauge is not faulty the resistance of the sender would need to be checked.... if you disconnect the fuel pump connector at the tank you can check the resistance to see if it is open and make sure that it is getting power and ground.... if you would like a diagram or further instructions let me know i can get them for you.

96 Mercury cougar gas gauge won't work


Cathy, 1996 Mercury cougar gas gauge not working. Simplest thing to check first is your fuel gage fuse, make sure all fuses are good. The ground wire could be corroded/damaged, sending unit in tank faulty, fuel level gauge in cluster faulty. All things can be tested by a good Tech.,diagnosed and estimate for repair.

1970 Ford F100 Gas Gauge Not Working


It may be the sending unit in the tank that needs replacing. Here's how you can check: Turn the key on and disconnect the sender unit at the gas tank. Ground the sender unit's wire with a jumper wire from the truck's harness to ground. Watch the gauge. If the gauge on the dash is good, grounding the sender wire will cause the gauge needle to react and should move to full. This would indicate a new sending unit is required. If the gauge doesn't move when the sender unit is grounded, the gauge is bad and needs replacing. Pull the instrument cluster out to replace the gas gauge. Likely any old ford gas gauge might work-back then, there were not so many production changes.

I have a 2000 buick Le Sabre. gas gauge does not work properly. i filled the tank and the gas gauge reads full. and it works properly past half. then it starts flucturating. i disconnected the gas gauge...


There are three possibilities. The gauge could be defective. The instrument panel voltage regulator could be bad or not grounded or (most expensive) it might be the sending unit.

Gas gauge is not working


sounds like you have a grounding problem... the gas gauge works off of resistince....if you ground the gas sender wires you should see the gas gauge drop.. if not check to see if it will drop closer to the gauge.
