turn both the controller and the car on. then while both are still turned on pull the crystal from the car then plug it back in, see if that helps at all ..
im not sure the reason behind this, but i had this same problem with one of my cars before. it was a quick fix to get the car moving when i wanted to drive it, but a real pain in the *** having to do that every time i went to drive it after turning it off.
in the end i just garbaged the crystal and used ones that worked!
