What to Do If the Fuel Tank Cap Won't Open?

[JamesFitz]

If the car fuel tank cap won't open, you can use tools or other methods. Specific related introductions are as follows: Fuel tank cap stuck or rusted: You can insert a small wooden piece into the gap of the fuel tank cap to pry it open. Remember to pull the fuel tank cap's lock switch while prying. Pull cable too long: If the pull cable is too long or has stretched after prolonged use, it may not fully engage when the handle is pulled, causing the fuel tank cap to not open. Another reason could be issues with the handle or the lock mechanism of the fuel tank cap. Fuel tank cap pull cable detached: Open the trunk, and on the side of the fuel tank cap, there is usually an interior panel that can be opened (secured by a few plastic clips). Once opened, you will see the long pull cable for the fuel tank cap—just pull it. If it doesn't work, try moving the movable parts of the lock mechanism while pulling the cable. Some cars have a dedicated lock switch on the lock mechanism. Fuel tank cap spring lost elasticity: You can install a small spring (not too soft or long) on the protruding rubber pad of the fuel tank to increase elasticity between the fuel tank cap and the locking device.
