How did you verify that you do not have spark at the coil?
The hi/lo res signals of the optical sensor of the opti (cam sensor) are sent to the PCM, the PCM sends a signal to the ICM which in turn triggers the coil to fire. Then the spark travels to the cap and rotor side of the opti and gets distributed to the proper cylinder.
I would check the grounds on the coil stud, should be three of them. Also check the ground from the stud to the chassis.
Swapping in a new coil would be a quick and easy test.

the car trys to turn over, i get no spark from the coil, the only code im throwing is a high input on ignition which i have had for 7 months or so.
i am gonna try to see if im getting power to the module as soon as i can check it. and someone suggested the pcm being bad so i put a stock one in and it didnt change anything hope this helps.

You say you've had the code for 7 months and your coil and ICM are 6 months old...hmm...sounds like that's your problem right there.
