fuel gauge not working

Most likely the fuel sending unit has failed, probably because the contacts are dirty

The correct thing to do would be to drop the fuel tank and replace the fuel module, which consists of the fuel pump, sock and sending unit

However, you might have luck if you start using top tier fuel, which has a lot of additives

I had a similar problem on one of my cars, and I started filling up at Costco, which has top tier fuel. The problem was instantly fixed. And that was a few years ago

Give it a shot

By the way, dropping the tank on this vehicle is a little bit tricky, because of the design of the fuel tank attaching hardware, and the way the parking brake cables are routed.

Just to be sure, your vehicle is a 2005 S-10 Blazer with the 4.3 liter V6, correct?

I’m asking because I’ve never run into a 2005 Blazer. The newest I’ve ever seen was a 2003 model.
