I filled my tank the other day and the gauge hasn't moved in 3 days. Unless I am blessed, I am guessing there is a problem. Anyone have any ideas? I just had a fuel pump put on in the last few months but it was fine until Saturday.

The float may be stuck,there is a bad spot in the sender or you have an open circuit to your guage.

I have the same problem. Rumor has it that gm fuel sensors are extra sensitive to sulfuric (bad) gas, and the electrical contacts are easily destroyed. I checked into fixing it... about $400 to replace at the dealer. Even worse, my regular mechanic (a reputable Delco parts dealer & family friend) says the sensor is only available to him as an assembly which I think he said includes the fuel pump & costs $600 FOR THE PART ALONE! Sad... I've gotten used to watching he tripometer.

I just found this:
GM PART # 25314231
CATEGORY: Fuel Tank Meter Sender/Connector
PACK QTY: 1 CORE CHARGE: $0.00
GM LIST: $114.28
OUR PRICE: $57.14.
At gmpartsdirect.com. This IS the part number I got from the GMdealer. I'll have to call my mechanic again!

gmpartsdirect is good, but watch the shipping charges..sometimes the price difference only adds up to be a couple bucks

Could try smartly hitting the dash above the gauge, to see if the needle will dislodge. Otherwise it's multimeter time...
