Question about 2005 Chevrolet Cavalier
No....the fuel gage sensor in the fuel tank has probably broken...some cars you can simply replace the sensor, but on most you have to replace the fuel tank.

There is not specific FUSE for fuel gauge; check other components.This is so typical. Many gas gauges don’t work for simple reasons. In would strongly suggest you read this whole document before proceeding. You may want to attack this problem in a different way. Please bear with us. This is a very difficult thing to write. Just a note. Our cars are usually **** pretty well by the time we get them. Make sure your wiring under the dash is in good shape. If it’s not, I would suggest you start there. Having seen some of these chimpanzees at work, you’re liable to find anything under there. Maybe the problem. Most people are apprehensive with auto wiring. It is really quite simple and you can’t get hurt with it. Just remember your body is the ground, and the wires carry the voltage. BUT! There are a few ground wires under the dash too. So be careful when you splice something. Here are the components: Gauge assembly Sending Unit Wiring from fuel tank to dashboard. Dash wiring. Voltage Limiter (Regulator) There are FOUR of the most common problems. 1. Defective Dash Voltage regulator (Voltage limiter) or gauge 2. Lost of a ground at the sending unit 3. Break in the wire going to the dash 4. On some Chryslers, the Bulkhead connector on the firewall or connector behind kick panel. Less Common 1. Actual bad Sending Unit 2. Fuel Gauge defective Tools needed for the basics: Alligator Clip jumper (Make sure it works) Test light probe Radio Shack or equal Multi-meter If removing the gauge cluster, you will need a socket set, a couple of #2 Phillips screw drives and a pair of needle nose. Gas Gauge and Temp gauge doesn’t work. (Reason #1) Let’s ask a simple question here. Does the temp gauge work too? Both the Temp gauge and the fuel gauge use a voltage limiter. Given the way these cares were built, it is hard to get too get to that. But before we dig into this, check the fuse for the instruments. That fuse feeds the voltage limiter. In time, voltage limiters tend to go bad. If one burned out, it may have blown the fuse. Which in a way is a good thing. If the fuse is good and the temp and Fuel don’t work, then chances are it’s one of two things. Lost the ground or the limiter is bad. After you are sure the fuse is good, (Check it with the Key ON), we can go for the checking for a ground to the cluster. If your cluster is back lit, and the dash lights work, chances are you have a good ground to the dash. If it’s front lit like the Mopars of the early 70’s, then we need to check the ground. If you have any lights on the dash, oil light (Idiot Light) turn signal indicator and they work, then a ground is established. If all these things are good, then you have to go for the voltage limiter. This is where the fun starts. Depending on your brail skills, you should be able to at least find it on the back of the cluster. If you can’t, then you’ll need to remove the cluster. A good suggestion here is to make sure you have any other under Dash tasks on a list ready to be done. I strongly advise you disconnect the battery while removing the cluster. Once out, you can reconnect to finish your test.It looks something like this. Since you are going this far, it’s a good idea to just replace the regulator anyway. They are available from NAPA or any decent auto parts store. Most of those chains don’t know anything about it unless it’s in the computer. Remember, you are dealing with people that only need a license to breath in the big chains, Brains weren’t applied for. continue...
