Im wondering on my buick whats going on with the gas guage, its past full all the time, so I was thinking it was a bad ground! Im a young fellar, and this is my first buick. I got underneath to see the ground on the tank but there was nothing underneath as far as wiring to the tank. Any Ideals or helpful tips will be appreciated! Thanks!
Could be a stuck tank float?? Get a bunch of your freinds to help ya shake the rear of the car side to side.. That might help knock it loose again....... It's worth a try. Let us know if it works!
