Please can some one help. I have just got hold of a 1992 Isuzu trooper duty and its currently showing a fault with the fuel gauge and I want to know where to start looking as I admit I don't have a clue I'm not to bad with mechanics and believe with some info and help I can resolve this problem Justin don't know which fuse covers this etc etc
Please help scotty

 

Anything that has to do with a gauge has a good chance of a poor ground wire! Engine to firewall, dash cluster ground, or sending unit ground.
