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.

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.

Where is the fuse for peril gauge in a Citroen c1

Find the problem? No separate fuse for the gas gauge, if the rest of dash and gauges work (the temperature gauge), not a fuse problem.

Take off the electrical connector at the gas tank, find the wire for the fuel sender unit in the tank to the gas gauge, and ground it temporarily to the car body, with the key ON. If the gas gauge needle jumps when grounding the wire, the gauge is good, and the problem is with the sender unit in the tank.

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.
