Can cold weather cause a car to not turn over?
It's a common occurrence as low temperatures can cause your car battery to produce less current, making it that much harder for your engine to turn over in the morning. The cold can also stop your engine oil from flowing as well as it should, which puts even more strain on the battery.
Can cold weather mess with your engine?
When temperatures dip below freezing, your engine is already aware of this and adjusts by introducing more gasoline into the fuel mix. By letting your car idle, you're subjecting your engine to more gasoline-rich fuel than necessary, and this ends up stripping oil from your engine's vital components.
What happens when a car is too cold to start?
In cold weather, engine oil becomes thicker and doesn't flow as well, so moving the engine parts through it is harder. That means that your battery, which has been weakened by the cold, actually has to do more to get the engine moving so it can start.
Where is the cold start sensor?

Do engines run better in cold weather?
They run more efficient in warmer weather too as the engine oil isn't thick as it would be in cold winter weather. Cars prefer very cool weather. When the weather is cool it is more rich in oxygen which cars use and because it is more rich in oxygen it more or less means the car becomes very slightly more powerful.
What happens to car in cold weather?
A vehicles engine compensates for the cold temperatures by creating a high gas to air ratio, using more fuel. This increase helps prevent stalling, which is the desired effect but it also burns through more gas than when it's warm.
Why you shouldn't warm up your car?

A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. If you have an RPM signal, a bad ignition module or PCM may not be switching the coil(s) on and off.
