Having problems with your Chevrolet Cavalier ?
Fuel gauge stopped working - Cavalier Chevrolet Cars & Trucks
Can't say for sure since you did not include year of your car but more than likely it's the fuel sending unit that requires replacement. Some years you can replace just the level sensor on the fuel sending unit but both repairs involve dropping the gas tank and opening to remove the fuel sending unit.
In the 2002 Silverado the fuel sending unit and the fuel pump are together as a single unit in the fuel tank. DO NOT remove the fuel tank. It is much easier to remove the eight bolts that secure the bed to the frame, lift the drivers side of the bed and place a jack stand between the frame and bed. This allows access to the top of the tank where the unit is removed. Parts cost about $250.00.
