1989 Chevy Blazer

Engine Mechanical problem
1989 Chevy Blazer Four Wheel Drive Automatic

I have an 89 blazer 4x4 and just the other day I come home from work and once I turn off the car it starts to leak a puddle underneath. So for the past two days when I do try to start it it would rev and continue to leak than die off. Iv checked to see if an of my hoses are torn or broken and from I see they are all fine plus some of them do have some water in them. But I dont exactly know what is wrong with it, mayb th water pump or the radiator and im sure there is probably no vaccum to it. It is leaking near and behind the passangers front tire.
