You could measure the resistance across the coils, the instructions are in the FSM but between two of the pins you should have ~1 Ohm of resistance.

I had a similar issue...I couldn't figure out why my car wouldn't start after installing my Electromotive ECU and harness...come to find out I forgot to connect the ground for the coils back to the intake manifold!!! Oof...did that and voila coils came to life. So, make sure your ground is good and/or connected!

Have you checked your CAS?

[crash41]

yes but ill still double check to make sure

check that you have +12v going to your IGNITOR- check the loom wire on the plug that goes to the ignitor its 6 pin i believe.. you have coil 1,2,3,4 then power(red) and black (earth)......... and reground the earth cable on the ignitor. its very simple.
