What would make the gas gauge flicker from empty to full on a 2000 Chevy Astro Van?

i have seen many fuel level sending units go bad in the fuel tank. The little fingers on them wear off. If this is occurring in park or neutral with the fuel sloshing, it is a normal condition due to the buffer being disengaged in the cluster.

  • edit by jwko - if the tank was not full of gas and the guage went to full could also be a bad ground. Check grounds ( there will be several ) so you will have to look close.

The sending unit is probably bad, not unusual.

If the vehicle will stall and will not restart or appears to be out of fuel but the fuel gauge reads above empty, replace the fuel sensor assembly and auxiliary tank fuel level sensor if equipped. if not, replace the instrument cluster.
