Hi,

Have you checked to make sure the crankshaft position sensor is connected? That can prevent spark to the plugs. Also, do you have power to the coils? Each coil will have a green wire with a white tracer that receives power via the ECM relay. Check to see if there is power to that wire on any of the coils. See pic below.

Let me know.
