Electrical problem
2003 Buick Rendezvous 6 cyl Front Wheel Drive Automatic

The fuel guage on my Rendezvous acts funny. When I first start the car it reads full. After about 20 to 3 seconeds it drops down at once to empty and the low fuel light comes on. It doesn't matter if I'm parked or if I'm driving.
A mechanic told me that it could be due to the fact that the car was sitting for a while. He suggested I drive it for a while and see if the problem goes away on it's own. It's been two weeks and has not gone away yet.

Chances are it is a bad rheostat on the float. The float is part of the fuel pump and in the fuel tank.
