Maybe the fuel's not getting into the cylinders. Try starting fluid (ether) into the intake to see if it catches at all. Combustion is simple. Fuel, air, spark. In the right proportions at the right time, to be sure.

I have an 02 Blazer in my stable as well.
I know you said you have spark. but I am willing to bet it is weak.
Inspect the cap and rotor. No matter the quality or manufacturer, I rarely get more than 13-14 months out of a set. OEM, Delco, aftermarket, zero difference.

New cap rotor and wires already. Even tried a coil from a running car. Still no start..

Did you ever get it running, I had the same problem and it turned out to be the engine temp sensor,(not the one for the temp gauge) it was kind of under the thermostat housing as I remember.
Changed it and it fired right up.
If it doesn't send the correct signal to the ECM the fuel won't be right and it won't start.
