How to Deal with a Fuel Tank Cap That Won't Open Automatically

[StJayden]

The reasons and solutions for a fuel tank cap not popping open are as follows: 1. The fuel tank cap is stuck or rusted: In this case, you can ask a gas station attendant for help. A slight pry or tap, while pressing the fuel tank cap switch, should open it. 2. Motor damage: Some vehicles have an emergency fuel tank cap release located under the cover on the side of the fuel tank cap in the trunk. Pull the emergency release with some force while pressing the fuel tank cap to open it. After refueling, check the control circuit of the fuel tank cap as soon as possible. 3. The fuel tank cap spring has lost elasticity: The owner can handle this by adding a small spring to the rubber pad on the fuel tank protrusion to increase the elasticity between the fuel tank cap and the locking device. 4. The fuel tank cap is frozen due to cold weather: In this situation, you can pour hot water or force it open. It is recommended to regularly clean the fuel tank cap. There is usually a drainage hole under the fuel tank cap. If this hole is blocked, or during car washes and snow/rain, it can easily accumulate water, which will freeze and cause the fuel tank cap to get stuck.
