Could be a faulty gauge. I'd reseat the harness going to your cluster first. It could very well be your sending unit too.

Do you have a 2nd cluster to test the gauge with?

The sending unit is in the top rear of the engine, drivers side, pointing up. Reseat that connection also.

or try resetting your entire system, disconnect the negative battery cable and keep it disconnected for a minute or so and then reconnect

Ive been told by a local guys it could be the sending unit. I don't have another cluster to check it with, but i had thought of setting the system and see what that does cause its an easy thing to try. I'll also try to check the connection on the sending unit.

Do i have to take the engine cover off to get to the sending unit?

Thats what im figuring also. But just to try it I'll do the battery trick. Will it hurt for the truck to be driven like this? Cause im going to have to get it to a shop.
