The trunk of my peach tree bark is splitting and it's oozing sap. In one area on the trunk, the flesh of my tree is showing and it has a large crack. What do I need to do to help my tree?

What you are seeing is gummosis - it is a gum/sap that oozes in response to injury, whether by insects (peach tree borer), mechanical injury (such as by pruning), winter damage, or virus/disease.

Below are links that will assist you in diagnosing your tree. The Cornell fact sheets will also help you in repairing your split bark.
