Hi th725b, This could be a 2 person job. Have someone hold the fuel filler release lever/button to the point that it should open - and hold it there. Now, using a credit card or plastic spatula (so you don't scratch the paint) push it between the fuel filler door and the body panel. Gently, pry it open and adjust the spring mechanism that should be allowing the fuel filler to open properly. Hope this helps!

The tab for the gas flap is located on the left side center. If using the credit card method - that's where you push in; The emergency unlock is obviously the preferred method if you can get into the trunk ( also vacuum operated lock ).
