1. Check the fuel level sensor: The fuel level sensor is located in the fuel tank and measures the amount of fuel in the tank. If the sensor is faulty, it may be sending an incorrect reading to the fuel gauge. You can check the sensor by removing it from the fuel tank and inspecting it for damage. If the sensor is damaged, you will need to replace it.
2. Check the fuel gauge: The fuel gauge is located on the dashboard and displays the amount of fuel in the tank. If the gauge is faulty, it may not be displaying the correct reading. You can check the gauge by comparing the reading on the gauge to the actual amount of fuel in the tank. If the gauge is reading incorrectly, you will need to replace it.
3. Check the wiring: The fuel level sensor and fuel gauge are connected by wires. If the wires are damaged, the signal from the sensor may not be reaching the gauge. You can check the wires by inspecting them for damage. If the wires are damaged, you will need to repair or replace them.
4. Check the fuel pump: The fuel pump is responsible for delivering fuel from the fuel tank to the engine. If the fuel pump is faulty, it may not be able to deliver enough fuel to the engine, which can cause the fuel gauge to read incorrectly. You can check the fuel pump by listening for a humming noise when you turn the key to the "on" position. If you do not hear a humming noise, the fuel pump may be faulty and will need to be replaced.
Once you have identified the cause of the stuck fuel gauge, you can then repair or replace the faulty component.
