Gas Gauge

5777 Views 5 Replies 5 Participants Last post by  CMill
My gas gauge started acting up a few month ago, can anyone help me narrow down what this could be? It works from 3/4 to full and empty to 1/2 but for some reason from 3/4 down to 1/2 it's dropping to completely empty and back up. My guess is it's a loose electrical connection but i have checked and can't find one, thoughts?

If it works in the same areas consistantly, It is most likely the sending unit in the tank. If it is the sending unit, I doubt it will be a cheap fix. It is not too common for a sending unit to go bad on an '03, though, but your description sure makes it sound like it is.
yeah, mine started doing that about a year ago. I just learned to live with it since I figure it was the sending unit that wouldn't be cheap to fix. I use the trip meter mostly now for gas monitoring anywho.
Mine does the same thing, I pulled the tank down to try to figure it out, tested the sending unit and what not all was good.

What I did manage to do was break the filler neck above the tank which caused the dreaded "check engine light" to come on.

I brought it in and they wanted 400 to fix it, it's not that hard oa job, just a slow one so I will be doing that myself.
I had the same problem on my 87 toy truck. It was the fuel sender. The dealership mech replaced it in under an hour and I was out a meer $85.
I'll pull the tank this weekend then, I was hoping not to have to but oh well. Thanks for the help!
