You need to check for spark, fuel injection pulse, and compression, see which one you do not have causing the no start.

Verify your ignition timing is set up correctly, also could be a bad engine computer. You need a scan tool to check rpm signal while cranking the engine.

I can send you a wiring diagram of the engine harness. You are going to need a meter to diagnose.
