Why does the fuel gauge not move after refueling?
1 Answers
Fuel gauge needle not moving is usually caused by a damaged fuel level sensor (fuel float). Below are explanations for why the fuel gauge doesn't move after refueling: 1. Wiring and instrument cluster issues: Take the car to a repair shop to have the two wires of the fuel float connected together. If the fuel gauge needle goes to the top, it means the fuel float is broken. If it still doesn't move, check the wiring and instrument cluster. 2. Needle not moving after full refuel: If the needle doesn't move immediately after filling up the tank, it's because the fuel float is pushed to the very top of the tank by the buoyancy of the fuel, causing the sensor-connected needle to remain stationary. Only after some fuel is consumed and the float descends will the needle move with the sensor.
