It's uncertain, but the car can run without a cam sensor once it is started. I've never attempted it but supposedly you can unplug the cam sensor after starting and it will continue to run.
There is a possibility that the ECT sensor or ACT sensor is failing sending a wrong signal to the PCM in ambient temps causing a too rich to start mixture. I know there was a issue with the ACT connector causing high resistance with age as well but all this is just speculative without actual measurements to compare to expected values.
