The solutions for a car not displaying fuel level are: 1. Turn off the ignition, lock the car, wait for ten minutes, then turn the ignition back on to see if the fuel level is displayed; 2. Visit a 4S shop or repair shop for inspection and maintenance. The fuel gauge consists of a voltage regulator's fuel indicator and a fuel level sensor. The low fuel level warning device is designed to illuminate immediately when the fuel in the tank falls below a specified level, alerting the driver. Precautions for using the car fuel gauge include: 1. Do not wait until the warning light comes on to refuel, as too little fuel is detrimental to the fuel pump's normal operation and reduces its service life; 2. Indicator deviation. When replacing the battery or fuel filter and restarting the vehicle, the fuel gauge needle may show a lower level than before. This is due to pressure release after opening the fuel tank, causing the fuel level to drop, and such display deviation is a normal phenomenon.
