Duster Wont Start

It has been about two weeks since I started it, but before then it ran fine. The car turns over, but it wont start. I checked the coil (which is new) and it gets a spark, but the number 1 plug isn't getting fire. The wiring to the coil is in good shape. The coil gives off a yellow spark; is it too weak? I mean, the car hasn't been driven yet, so either the coil is going bad, or the wiring just "up-and-died."

Any info is appreciated.
