even tried bypassing the security module by cutting the yellow wire and black wire and putting a 2.2k ohm resistor in line. It cranks fine but never turns over.

You saying it turns over but want start, have you checked spark? Fuel pressure, injector pulse do you know how to and have the tools to check these
Customer: replied 1 year ago.
We replaced the coil pack so spark should be fine. When fuel pump was replaced pressure was good. It cranks but never seems to start.
Expert:  Reggie Whiddon replied 1 year ago.

We cant count on spark being fine you could have a problem with crank sensor or pcm please pull a spark plug wire and check spark. And we need to know the fuel pressure if its low by a few pounds youll have a starting problem. and fuel injector pulse, and scan the pcm for codes
