Since i bought the car the fuel gauge wasnt working properly, only the reserve light works, most of the time its just shows full and when reserve light comes on it goes to empty. also jumps around now and again..

It sounds like the float in the fuel level sender is stuck at the top of the cylinder. Try pulling the sender unit in the tank out and see if the float is sliding up and down. I'm sure someone with more knowledge than me will be around with other ideas soon :)

chinchilla,

It could be something as simple as a poor connection at the rear of the dial- check that the wire is clean and that the nut is tight before you start getting involved with the fuel sender

as marty1979 says, there is a likelyhood that the sender in the tank is stuck- have a look at this link to see how to take out the sender :cool:

Before you take out the sender, pull it's plug off with the ignition on and check that the fuel gauge goes to zero. If it doesn't, you're looking in the wrong place.
