The problem is either a faulty fuel sending unit located inside of the fuel tank, the wiring between the fuel sending unit and the fuel gauge, or the fuel gauge itself is malfunctioning.

A good repair shop can find out for you which one is at fault by dis-connecting the wiring connector to the fuel sending unit and then use an adjustable ohms box to simulate the fuel sending unit, and the fuel gauge should read at a certain level of fuel according to the amount of ohms being put through the wire.

Gas Gage Problem

You should start by asking friends or associates for a mechanic/technician in your local area that is considered reputeable, knowledgeable and resonably priced. If you have doubts about any business call the Better Business Bureau (BBB) first. Good Luck!!!!
