Why does the fuel gauge not display after refueling?

[ORhett]

Check and troubleshoot: If the fuel gauge needle does not move and the indication is inaccurate, it indicates that the fuel gauge is not receiving a signal from the fuel level sensor, suggesting a malfunction in the fuel level sensor. To address this, perform the following checks: 1. Loose fuel level sensor connector: Inspect whether the fuel level sensor connector on the fuel tank is loose or shows signs of oxidation and burning. If so, clean or replace it. 2. Fuel level sensor sticking: Remove the fuel level sensor, place it vertically, push the float to the highest position, and allow it to freely fall to the lowest point. Then invert it, push the float to the high point again, and let it fall freely. Observe whether the float slides smoothly without sticking. If sticking occurs, clean or replace the sensor.
