If one cylinder is cold, it has to be missing fuel, air, or spark.
Since you know it's sparking, and the other cylinders are getting all three..... I'd be checking out the injector for that cold cylinder. Make sure the wiring is good and the electrical connection is good.

"There's this adage that we have 2 ears and one mouth so we should listen twice as much as we talk. Unfortunately with the Internet people have taken this old adage and turned it around. They have two eyes and 10 fingers so they think they need to post 5 times as much as they read. And since they have 10 fingers and one brain, they only have to think 10% of the time! "
