GM gas gauges are wired so when the circuit is open the gauge will go way over to full. Ground the wire at the sending unit & see if the needle goes to empty. If it does your sending unit is bad or not grounded. If it doesnt change you have an opening in the wire between the gauge & sending unit. smile


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
