boxster wont start after filling the tank.

I don't understand what one stuck intake valve have to do with the engine not starting after filling your tank. If the engine is injected then fuel stops when you turn the engine off and pressing the gas pedal wouldn't do anything either. I am by no means a Porsche mechanic but have worked on cars and trucks to include supervising 2 other mechanics in the military. I guess I just think further information would be helpful.
