Common GM problem for the fuel gauge.

Yup, common problem on GA's & some GM vehicles.

See: Fuel Level Sensor (http://www.grandamgt.com/forum/showthread.php?t=14550&page=1&pp=20)
& see the Toronto Star newspaper article that is in page 2 of that thread:
from: Toronto Star newspaper, Saturday, Dec 20, '03: Why the fuel gauges in GM cars don't always work. Company has part that can fix problem. Ottawa says gauges don't pose a risk.


Try using a total fuel system cleaner (not just an fuel injector cleaner) in the gas tank.
I know it has worked for me the last 2-springs, when my full gauge started acting up again.
After a few gas tanks later, my gas gauge return to normal operation.
