The front plugs are 2, 4, and 6. 1, 3, and 5 are in the back (which is actually the right side of the engine)
You tested the ICM but not the coil packs. They may look fine, but if you can test them...
Crank sensor is not fun to replace. I don't have the tools for the job and that is what mine needs. Did you have problems when flooring the car?
The Cam sensor is a PIA, but it's not too bad. There's just too much stuff in the way. Did mine twice. Buy a good sensor like ACDelco or a Wells. I bought the cheapest one and, yeah 13 months later (1 year warranty

)
So which plug is not sparking and what is the other plug on that coil pack?
I'm thinking it's fuel related or the igntion switch
