Turn the ignition on and off several times before inspecting the gas tank because a blown fuse is the usual cause for fuel gauge malfunctioning. If the gauge remains motionless, check your fuse box and determine the fuse's location using your service manual.
Replace the fuse if the link is broken or damaged. Then, inspect the gauge's wire connections for cleanliness and make sure the wires are connected.
Turn the ignition switch to the "off" position. Attach one end of a jumper cable to the fuel-gauge terminal behind the gauge itself. Attach the other end to the ignition terminal.
Replace the sender unit in the gas tank if the gauge reads full and your car does not have a full tank. Replace the fuel gauge if the needle remains inoperative.

Your in tank fuel level sending unit is more than likely bad.

  • Anonymous Jun 13, 2011

    It is the fuel level sending unit period. There is no fuse for the fuel gauge only. You need to drop the tank (replace the straps while your at it) removing the sending unit assembly and replace the level sending unit. The resistor corrodes over time and eventually opens up.

Why won't the fuel gauge work?

The power wire from the sending unit runs to the gauge. Since it is showing 3/4 all the time. It is a break in the wire or really high resistance. I would check resistance of the ground wire first. If it is good(less than 5.0 ohms), I would replace the power wire from the pump to the gauge. I assume the gauge goes to empty with the key off. If not the gauge is bad.

Fuel gauge faulty

The fuel sender is part of the fuel pump mounted on top of the fuel tank. There might be an access ti the top of the fuel tank through a removable access panel under the rear seat. Otherwise you need to remove the fuel tank. New unit will cost a lot

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.

Petrol gauge was working fine before a 5 week holiday. Car not used during this time. Now petrol gauge shows tank empty, even after I had filled the tank. What is wrong? How do you fix this?

sounds like the float is either got a hole in it and is full of fuel, or the whole float assembly is seized in the empty position.
was the car left for 5 weeks empty of fuel?
