Is there a steering column security system doesn't allow starts on cold mornings?

I posted some information about your security system on the other question that you posted where you mentioned the pellet in the key on your older vehicle.

Let me ask you this: Does the starter not crank the engine when you are experiencing this difficulty? Or is the starter cranking the engine and it just won't start?

The reason I ask is because if the starter cranks and your problem only occurs on cold mornings, the problem is most likely to be caused by a malfunctioning Engine Coolant Temperature (ECT) sensor.

In any case, you should scan your computer network for possible fault codes to begin any diagnosis of either your engine control system or your security system (Unless you really like wasting your hard-earned cash trying to "GUESS" what is wrong).
