How do you open a stuck gas cap door on a Nissan Sentra?

Answer 1

This is usually due to a broken coupling between the spring mechanism on the latch and the cable, located just behind the filling box. You will NOT need to replace the entire cable, or begin pullng the entire car apart to get to it. This is one of the few flaws on Nissans, and they should replace it for free, but they don't. Step One: Inside the trunk, gently pull the carpet covering away from the fuel door. Step Two: You will find an 8' diameter hole in the metal frame. Inside that hole is the cable. With a flashlight, you will see a white unit at the end of the cable, with two tabs that keep the unit in place at the fuel door. press those two tabs, and the unit will release into the fuel door area. Step 3: Gently open the fuel door, using a kitchen knife or small putty knife to get the door open. Do not force it, as you do not want to damage the car or the spring mechanism. Step 4: Pull the spring unit and cable out through the hole in the filling box. You will see that the cable part will snap out of the spring unit. You can replace the unit, or I drilled a hole in the spring plunger and wired the plunger to the cable. Step 5: Slide the spring unit with cable attached back into the hole. Done!
