the engine might freeze over
Please clarify what you mean by "crank up". Do you mean that the engine won't crank when it's cold? If that's the case it might be a battery problem. Sometimes a battery can produce enough current when it's warmer but the temperature drops, the chemical reaction will slow enough that it doesn't make enough current to crank the engine. Have the battery checked. When a battery gets to that point it is weak enough that it will show up on a routine test.
