Mynndawg,
Are you talking about the "lever" to pop open the fuel tank cover? If so, have someone pull the lever and you go check whether the small arm moves or not on the inside of the cover itself. If it's not moving, then perhaps cable got disconnected somewhere.
I don't think it's something serious but if the cable alrdy snapped, then it's quite tricky to have it replaced. Not sure where the cable is lined up on your car but try to trace it.
Good luck
