Try checking the ground wire that goes to your fuel sending unit,It is located on the frame next to the fuel tank, you will see the wire coming out of the top of the fuel tank to the top of the frame beside it, make sure that connection is good, If that does not fix the problem then it is probably a bad fuel sending unit.
Additional Answer : Also check the lead wire connected to the top of the tank using a test light (yes you can reach it by hand without taking down the tank though it is a tight fit). They are inexpensive tools that saves you a lot of hassle in the long run. If you don't get power to the tank (light does not come on) do not assume the sending unit just yet! Make sure you have a good connection and if that is still not the case then work your way up towards the the cab following that lead wire. You may find your problem is a lot simpler than having to drop the tank.
I've had this same problem and believe me I made the mistake to drop the tank first and change the sending unit when I was not thinking of checking the wire all the way up to the cab. Its a lot of work to jump into when all I found out later was that the wire had snapped in two right before you go up the firewall of the cab. Think outside of the box!
If the fuel gauge is stuck, the needle never moves, then the gauge has a problem and needs to be replaced.
Most of the time it's the fuel level sender in the fuel tank if your gauge moves around a bit but doesn't read correctly. If the Gauge is stuck on full all the time, the gauge itself is broken.
is the coolant disapeering at all ?
The gauge does not cause the heat; it only shows what it is.
it is a force
All the directions
It moves down stream by Monte' Cook
It's not supposed too.
it moves the material to different directions.
A battery gauge "moves up and down" while running because of fluctuations in the voltage output of the circuit which it is connected to. This may be because of equipment on the circuit.
It moves 12 places to the left.
Yes, it moves in multiple directions, it spins to drive the wheels and moves up/down when the tire goes over bumps.
Weak battery, or weak alternator.
03 chevy trailblazer gear shfiter moves but truck does not go in gear
Not always. Winds carry clouds in all different directions.
The weather moves in different directions in different locations.
Cause your mouth moves in different directions. That is one reason.
Can be loose connections or the alternator is failing.
It usually means that there is something wrong with the fuel gauge itself. It's like when the speedometer is out, just get i checked by the car manufacturer
They dont have dance moves becuase they just make it up as they go along but probably the most popular is the elbow shuffle :)
