This could be the instrument cluster or more likely the sending unit has gone bad. The sending unit is located in the tank and is part of the fuel pump assembly. It is a fairy intensive job. A normal shop will charge around 600-700 dollars to fix this. It may be easier to reset the mileage counter every time you fill up and then always fill up before the 250 mile marker. I hope this helps!

My fuel gauge doesn't work on my 97 Pontiac grand prix

my guess would be the fuel sender in the gas tank .the float is rusted stuck or just worn out . big job you need to pull the tank and the strap bolts usely break or need zip cut off .can be dangerous you need to get all the gas out of the tank . probably a job for a mechanic.

My 2002 grand prix gt gas gauge doesnt always read properly, when i fill it up reads right, but always says full rare times while driving it will read correct, and after driving i put in park, and let idle...

replace the gas tank unit. 99 percent of the problems of this type require the tank unit to be replaced. it is a flaw with the GM cars, that GM refuses to have a recall on.

1998 Grand Prix ...Last week I got gas when running real low and was in a rush. In my haste I noticed when I was leaving the ground around the tanks was dug around there. a couple days later my car started...

If I'm understanding you correctly, you believe you got contaminated gas from a station where they had recent work done on their tanks. If that's so, Now that you've run most of the gas out I would start by changing the fuel filter then fill the tank with good gas (I might even go up on grade for this tank). Although it's unlikely you may have gotten a fair amount of dirt or water, you may want to try adding some dry gas in case there is still water in the bottom of your tank.
If the new filter seems to clear the problem but it come back after a short while you'll need to take the tank off and flush it. If you do it yourself don't dump the gas on the ground. If you have to flush your tank you'll need to flush the gas lines and replace the fuel filter again.

97 altima messed up gas gauge???

very common problem, esp with high milage, the fuel vent system is plugged, because the charcoal canister has come apart and the particles have traveled thru and plugged the fuel vent valve, what happens is when you add fuel the air in the tank cant vent out as the liquid displaces the air and backs up thru the filler neck, this however can get costly.

Gas gauge not working

my 97 grand prix had a habbit of doing that.. it wasn't much though it would bounce between wherever it was at when i started to an 1/8th of a tank below that. depending on how much it does it and how far it bounces around i would have the sending unit checked (much cheaper if you are mechanically inclined and can do it yourself)

1999 Pontiac Grand AM 4DR. SE fuel gauge and other problems(help)

I have a 97 and an 00 Grand Prix and an 03 Pontiac Montana. The fuel gauge in all three vehicles don't work. The dealer here says it's a common problem in Colorado where I live. The government required additives in the gas cause corrosion problems with the fuel level sensor float linkage that sends the signal to the fuel gauge. The repair requires the removal of your fuel tank and replacement of the linkage and sensor. It would cost somewhere around $500. I've leared to reset my trip meter with every fill-up and watch the miles and check the fuel mileage with every fill-up to make sure I know when I'm about to run out.
