Having problems with your Oldsmobile 88 ?
I have a 1995 Oldsmobile 88 Royale and the gas gauge was working until the fuel pump went out and I replaced the fuel pump and sending unit and the gas gauge has not worked since how could i fix this
I would connect a 12v test light to the wire that goes to the fuel gauge at the connector near the fuel tank. With the ignition on the fuel gauge should go to full. If it does you'll have to take the sender back out and check it. If it doesn't you have a problem with the gauge or wiring. I suspect you'll find you have a sender problem.
