What causes a fuel gauge to get stuck and stop providing an accurate reading?

Well, usually there are several possible problems that can do this. Some of the more common problems that people experience with their fuel gauge is that it reads empty at all times, another is that it reads constantly full, but the most common problem is when the gauge will read differently at different times, fill the tank and it will read empty, be about a quarter of a tank down and it will read full, that sort of thing. In the more common cases, the problem is with the fuel level sending unit, I do not know much as to how to fix it, but I have seen several websites that give advice on this problem.

More often than not, a fuel gauge problem is usually a faulty fuel gauge sending unit in the fuel tank.


Gas gauge on 97 blazer not working.Shows more gas that actually in tank?

You need to replace your fuel sending unit, but you can't get just the fuel sending unit, so you will need to replace the entire fuel pump.


Where is the fuel gauge located?

The fuel gauge is located in cars. It is used to tell how much fuel is left in the tank. When this gets low the tank will need filling up with more fuel.

One reason could be the sending unit has failed.Since it is a part of the fuel pump assembly, inside the gas tank, repair/replace is not an easy job.See "Related Questions" below for more


Which fuse is for the fuel guage on a 2011 peugeot 508?

There typically isn't a separate fuse for the fuel gauge - it's a shared circuit, and you'd lose a lot more than your fuel gauge if that circuit lost continuity. If your fuel gauge isn't working, you're more likely looking at a bad fuel sending unit, not a fuse.

Temperature gauge keeps going up and down?

Temperature gauge reads signals off the coolant temperature sensor. It can also point to a faulty thermostat. If your car runs rough in cold, idles rough and uses up more fuel then coolant temperature sensor is your problem. They are normaly a cheap and easy diy to do.


You lost the fuel cap and replaced it on a 2005 TrailBlazer LS the fuel gauge jumps all over showing full then low fuel. How do you reset the computer?

The fuel cap has no effect on the fuel gauge and there is no "reset" for this. More than likely the problem is with fuel sending unit in the tank. A less likely cause is incorrect levels of additives in fuel, this can cause the gauge to flucuate erratically.
