Default 01 Impala fuel guage always FULL - 04-27-2007 , 10:59 PM






Hello:

The Fuel guage in my 2001 Impala LS always reads FULL. The guage will
fall to EMPTY when the key is off, but as soon as I start the car, the
guage reads FULL.

I assume I need a new sender?

Any tips on troubleshooting, or replacement is appreciated.

Have a nice day,
Bill

Could well be the sender Bill, and in fact it's pretty likely, but before
buying a new pump, check the wiring. Faulty wires account for enough of a
percentage of these problems to at least investigate.

and.....on many late model GM's their is a sender 'card' available so you
dont have to buy the pump module just for screwy guage probs. check with
your dealer parts man with VIN......kjun

There is an access hole under the carpet in your trunk. Remove the cover,
unplug the 4 pin connector. Short the purple wire to the black wire that is
the same gauge. Key on, if your gauge reads empty, then the sender is at
fault. If it still shows full, you have an open in one of those 2 wires. The
black wire is ground, the purple should have voltage. Diagnostics don't say
how much volts, either 5 or 12. Good luck!

Thanks for all of the help and replies.
Another question, do I need brass tools to pull the sender. Can I
unplug the fuel pump, start the car, and let it discharge the fuel
pressure? Finally, how do these 'quick connect' fittings work?

Thanks again for the help.

Have a nice day,
Bill
