It is unlikely that the Techron has anything to do with the problem. From what I understand, the problem occurs after the car has been sitting for a time.
If that is the case, I would suspect the fuel check valve / return valve / pressure regulator / whatever you want to call it. Its a valve that regulates the fuel pressure when running and holds the fuel pressure when sitting.
If the regulator is defective, it allows the fuel to leak pass it as it sits thereby allowing the fuel pressure in the lines to drop. You then try to start the car, and there isn't enough pressure to start the car until the pressure can build back up from the pump running. This would be exacerbated in colder weather because the colder the temp, the more fuel the engine needs to start.
