Start with the simple things first, you're going to have to pull the plenum if it's not the spark plug.
Coil packs do fail, if you have a DVM, compare a working coil pack to #1's coil pack.
Only a very few DIS have failed that I've heard of over the years, and it's usually associated with a whole litany of other problems that kill the DIS.
