Hello on my 2002 Pontiac Montana my gas gage work only sometimes. It either reads full or empty never in between. Any clues on what this could be? Thanks,
 
could be a bad sender or the ground for the sender
 
I have a similar problem but the gas needle likes to move all over the place. Am I stuck with replacing the sensor in the fuel tank or do you think if I ran new wiring I might solve the problem?
