Hi,
Recentely changed the fuel pump unit on a Grandam 1993.(complete unit including gauge gotten in a scrap yard)
Since that time, the fuel gauge indicates full as soon the switch is on when the tank is not.
Is it a sure indication that the tank fuel gauge is defective or could it be a wiring connection problem.
I just bought this car and I don't know if the previous gauge was working properly.
Any opinion or idea about the testing I can do.
Thanks for your help.
Daniel
