Why won't my car fire in colder weather? on 2006 Ford Fusion

I plug in at any temperature lower than 20 F or else it won't fire. Today the car was parked for 8 1/2 hours outside to day and wouldn't fire but turned over fine.

could be a number of things but first I would run some gas line antifreeze in it

I tried that and no change. The parts store thinks it is the engine coolant sensor.

I would have it scan tested for codes and then you can check the temp reading for the sensor
