Regardless of what you did, if you only disturbed one DV then I doubt the car isn't starting because of that. I suspect you have it air bound and need to purge the air from it again. The car will start and run on 4 or 5 cylinders so being without one would not prevent it from starting. I would not give up on it yet...you ought to be able to get it running again if all you did was disturb one DV.
