I've just recently purchased a 92 Chevy blazer s10 from a friend of mine. It cranks but it won't Start.

 

First thing is to determine if its ignition or fuel. Do the fuel pressure test in the sticky and if that good then check for spark. Once you find the issue we go from there.

There are some less common and more involved possibilities like timing, compression, etc but lets start with the basics which are most likely.

This might help:
