The popping sound would indicate a very lean condition on a cold start which in turn indicates that the ECU is not compensating for the cold coolant temp. Since you have replaced the ECT without any results, and disconnecting the wire allows you to run, I would suggest checking the length of the wire for a bare place where it may be grounding to the chassis. If you have a spare ECU, you can swap it out and see if it has failed also. My bet would be in the wiring insulation.
