Fuel Gauge & Engine Code

The code means you have a bad wire/connection to the fuel sender unit or at it, unless your computer is the hiccup then no, then its otherwise non-connected hiccups.

May just need a tune up, If your dealer wants to do a fuel pump repair, may be a good idea to investigate how to access your intank fuel pump. I am not 100% sure on yours but do know that older Pontiac models had Fuel Pump access panels just above the fuel tank, Under the carpet flooring of the trunk or in between trunk and cabin, or behind back seat. I would check for this panel and see if there is loose connections, if handy you could even pull the sender unit yourself and check it out for issues like loose float or wire to float arm ect. or even replace the sender all together, days of dropping the tank are over. Your should have this access panel. I have still heard of shops including dealers still charging fuel sender replacement charges as if the access panel were not there and they drop the tanks down to replace fuel senders, this is wrong, if you are not standing there correcting them on their charges they let you believe the tank came down, Which adds about $450 to the cost to repair, Dealerships make 90% of their money on repairs and they count on everything they can get from you including up-selling you on other stuff they deem you should fix. It there bread & butter. I would for sure open the access and have a look around for loose, bad wires, may could just jiggle them to see if the gauge works a little, then trace to the bad spot in wire and fix and check ground wire to body/frame.

OK thanks for the input!

Your welcome.
