It should fire right up in the cold. Mine starts withing 3 seconds nomatter what the temperature, and that is without the AAV. When I lived in IL the car was started once a week all winter long.
If your engine did not chug to life when it fired up I would suspect the cold fuel pressure is OK. That leaves the cold start valve and spark. There is always the looming odd issues caused by vacuum leaks as well.
Do report back if you can get it to repeat and what your findings are. Good info for aging cars.
One more thing I just thought of, check valve. If your fuel pressure drains off completely when cold it will take longer to start. This condition however is not dependant on temperature.
