When it is very cold in the morning my blazer will not start! If it does start it is after trying for about 5 minutes of cranking it. When it is warm it starts right up with no rpoblems. What will cause it to do this when it is cold?

More then likely you have a bad coolant temperature sensor and a dirty throttle body.

Secondly, say you park it in a heated garage overnight will it fire right up? If not you may have a bad fuel pressure regulator.
