Default Need some help.

My girlfriend drives a '97 Lumina LS 3.1V6 and the gas gague is going crazy. We'll be sittin there and it'* at 1/4 of a tank then it goes all the way up to full. This is at a standstill mind you not while traveling. It does however go back and forth when the car is moving as well. I read a post a while ago from someone with a similar issue in his Bonnie and I can't remember what the fix was. Anyone have any ideas????

Time to replace the sender. My GF had a 99 Lumina that did the same thing, but we never changed it out because we filled up once every two days (around 250 miles).

Well, the typical failure mode that causes this on the Bonnevilles is a bad fuel gauge sender unit, usually located on top of the fuel tank by the fuel pump (for Bonnevilles - probably similar or the same in the Lumina).

Usually, if not fixed, the gauge will eventually stop working completely. Many times the sender failure indicates other problems up there too, like rust.

Point is, you need to take a good look up under there and see what you can see.

Search on "fuel sender" or "bad gas gauge" or similar terms for threads dealing with this.

Because her foot is heavier than mine and she has already gotten three speeding tickets in the last year and our insurance (and my wallet) can't handle any more.

Like I mentioned, this has been covered in detail a few times on here, this year alone.

Search on "gas guage" too.
