My friend has an '02 Ford Taurus and sometimes the gas gauge works and sometimes it doesnt.
He said it will be working fine and then when he shuts it off and starts it again the gauge is buried on empty.
Other times it works fine.
He replaced the sending unit a few days ago and still has the issue.
taurus,s are known for bad gauge clusters i have seen them numerous times ,its g/m that has the bad sending units in the tank,oh and hooked if ya use my ford line again ill beet ya ;D
