What happens if your car freezes in the winter?
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. If there’s any water in the fuel lines (there shouldn’t be, but it happens), sub-zero temperatures can cause that water to freeze, blocking the flow of fuel.
