SOURCE: fuel gauge not working properly.

Could be 3 thing - the gauge on the dash, the wiring or the fuel level indicator in the tank. All three are not easily accessible - the best test would be to measure the voltage on the level sensor on the tank.

It usually means removing the fuel tank and start measuring. If its ok, supply voltage to the lead towards the fuel gauge. If the gauge doesn't move it's wiring or the fuel gauge itself.

My 2012 mazda 3 isnt reading fuel levels properly.its reading empty with 20L or 5 gallons of gas in it,also its not reading full even when gas is almost running down the side of the car.

Your fuel gauge sending unit is inside your gas tank.
It is likely defective, and may need replacement.
Some Mazda dealers may have an electronic tester that will measure it's effectiveness.
Having had several cars with this same problem, I have always opted to live with it, but very likely a new sending unit is in order.
God bless your efforts.

Hi i have a 2004 mitsubishi endevor the fuel level guage out of the blue stoped reading how do i fix it please

Do you know anything about automotive electronic's ? The fuel level sending unit inside the gas tank is an input to the PCM/ECM / ECU - engine computer , the engine computer sends this information to the instrument clusters microprocessor over serial data network .The microprocessor controls stepper motor to control the gauge . Your best bet , take it to a qualified repair shop that has the proper diagnostic testing knowledge an tools , one being a professional type scan tool that can view fuel level sensor data to an from the engine computer .

Why fuel gauge not working gas guage on 2009 santa fe stays on empty even with a full tank of gas. Guage fluctuates from empty to 3/4 full to empty to 1/3 full at any given time.

It could be the sending unit in the tank or the gauge on the dash. A mechanic would test the signal coming from the sending unit to verify.

My fuel gauge floats from full to empty when I stop at a light! And its stays on empty until I drive for about five minute why is that? I can't get an accurate fuel reading!!

I have the same vehicle and my car actually was full of gas, registered empty & left me on the side of the road..It was the sensor in the fuel line that had to be replaced.

I have a 2003 GMC Envoy and my gas gauge has been flowing up and down to empty and full recently it has stayed on empty. How do I fix it?

Ensure that all of the wire connections are clean, secure and corrosion-free.

  • 2 Check your fuel gauge fuse if the gauge's indicator stays on empty when your turn on the ignition. If the fuse is good, join the sending unit connector to ground. Replace the sending unit if the gauge indictor moves to the full line.
  • 3 Ground the terminal located on the back of the fuel gauge with a jumper wire if the indicator doesn't move. If it does move, consider replacing the wire between the fuel gauge and the sending unit. A poor ground is frequently responsible for fuel gauge problems.
  • 4 Release the wire that connects to the fuel tank's sending unit. Confirm that there's no worn insulation that would permit wire contact to the body or frame. A fuel gauge reading of full generally indicates a problem with the tank unit, not the wiring.

    My fuel gauge isnt working, it sayed over Full untill i hit half a tank then showed on F then 1/2 a tank was actually Empty. what could be wrong?

    The fuel sending unit has a rhetrostat its a variable resitor ..As fuel is added the fuel lever mover along the rhetrostat and gives resitor signal to the fuel guage, the fuel gauge interpets this as level indicators to show on the gas tank.

    Fuel gauge not working

    yea fords with two tanks are known for getting stuck if you dont switch the tank constantly. you have to get to the valve that switches the two tanks, and free it up. it definitley isnt anything but the valve.
