90 fuel guage issues
My guage almost always reads full, I removed the sending unit, it checked good, but I cleaned the contacts and windings anyway. It still reads full, could it be the instrument cluster? What color wire does the sender use on the conector for the pump? One thing I didn't so is hook it up outside the tank to see if the guage changes. Also, when I relieved the fuel pressure, no gas come out. Is this normal after overnight?
Thanks,
Bill

Factory Service Manual diagnostic tree is here http://jacnsue.com/corvette/repairs/fuel_gage.pdf
Connector C450 is the connector to the fuel sending unit on top of the fuel tank. Getting to the CCM is a pain, but not impossible.
Good luck tracing this problem.
