Anyone with Fuel gauge malfunction??
Lately, my fuel gauge has been acting squirrely. It sometimes all of sudden goes from an actual full reading to empty causing my low fuel/reserve fuel indicator to come on. I have no confidence in the reading anymore. What gives??? Whats the fix for this???

Faulty fuel gage
My 2000 FRC had the same problem. Whenever the gas gage would read below half full the Low Fuel indicator would suddenly come on the DIC.
I just took it to the Chevy dealer last week for the column lock recall. The technician said that the reprograming for the column lock problem would likely fix the fuel gage problem so they did not charge me. I don't understand how the two are related, but it's working fine. I will continue running the tank down to see when the Low Fuel indicator shows up.

My 2000 vert did the same thing the day I bought it. The problem was with a defective sending unit in one of the 2 tanks. It's a common problem. There's a Technical Service Bulletin on it as well.

I took it to the dealer twice with the same problem in my 2000 and after the second time, about 20k miles ago, it was apparently fixed with no problem. I was told that it was the sending unit.

Same problem here on my '98 Vert. I'm on my second bottle of techron in four tanks. Problem is intermittent. No Chevron stations in my area - is Texaco using the same additives now that I heard they are owned by Chrevron?
So how hard is it to replace the sending unit? Any DIY instructions? My search didn't turn up anything a month or so ago when my problem started.
What is the Gm tech note say? Recall ?

I believe there are actually two TSBs on this:
One TSB covers the sender wires:

The other TSB covers the actual sender assembly and can be corrected with a PCM reporgram:

My gauge on my C5 is weird. It'll read right one second and say I'm out of fuel the next. It's really to bad that they do this because when they do read right they are really accurate from what it looks like. My C4 jumps around under a quarter tank from @110 mile range to 40s and back so I have to do an average in my head!
