Hi there. Anytime the battery is not disconnected and a wiring harness is removed, there is spikes of power that is sent directly to the ECM (computer). Either there is a plug that is not plugged in on your engine causing the vehicle to not start or there is an issue with the ECM. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your no start condition.
