UPDATE:

I talked to my buddy and he said that I should unplug the OBD tester and try and crank it. It doesn't even try to crank without the tester in and the fan comes on. But the second I plug the tester in the fan shuts off and I can hear all the relays clicking on, so I'm assuming some sort of anomaly is happening where the OBDII port is acting as a ground or completing a circuit in the wiring but I can't determine in what module specifically. I'm gonna try and find a wiring diagram for the PCM, the RCM ect and try and trace the sourc of the issue
wish me luck
