help is greatly apriciated. thanks

 

distributor cap, rotor, distributor itself, or power to the distributor. Check all 4.

 

3.3...

its a distributor-less systems.
the crank/cam sensor is brand new.
the coils and module have been checked out and are good.

 

bump

 

It could be the timing belt/chain. If so, the cam wont move so the ignition coils wont get the signal to send spark. I'm guessing this signal must go through the computer to determine if the spark needs to be advanced or retarded so it could be bad as well or not getting power for some reason.
