Default gas gauge reading full tank all the time

Does anybody now if it'* a typical reason why my gas gauge reads full all time....or at times it bounces from half to fuel tank even why the gas is low...someone told me it was the fuel sending unit does that sound about right?

for a second voice on this... it is most likely the sending unit. Both of my cars have that problem. ill just look at the trip meter and get gas every 300 miles.
thats the econo cheap way to resolve the problem

I have an 04 SE and mine started doing this in the past two days... If I remember correctly, while I was at NYBF, I was in between two white cars... is it possible that the white curse has been transfered to me? :(

Most likely. For the 00 folks..your swap is much easier. Hans posted a fix for under $40 and it'* quick to do since you have the secret hatch in the trunk.

92-99'* have to pull the tank down. You can crawl under and check the connections. Also there is a thread here somewhere about adding a resistor for fuel gauge issues..although I can't remember if it applies to this situation.

Yeah I've got the same problem...I can usually push 350-ish miles from my tank without getting too scared. Don't get me wrong, I absolutely love having a working fuel gauge, but I'm not ready to drop that kind of change getting my stuff fixed.

Boosty...can you tell us what connections to check as a starting point at least? Also, would you recommend unplugging and cleaning the connections?

Good luck to ya ShowShocka! Hope you get your mpg'* up!
