What is liter size of engine? Did you mean s10 instead of blazer? In my database, for 97 blazer it showed 4.3L engine with distributor, no coil pack. I did look at s10, 2.2L engine in that model year, it has a coil pack.
Did you visually check for spark at the plugs, involved? engine cranking, don't start it. Dis- able the fuel system if you need to, so it won't start.
The point is, with gm bypass ignition, during cranking, it's the ignition module that controls spark, not the computer. You could swap the coils to see if problem follows the coil, if it does, the problem is the coil. If not I suspect the ignition module. Just my opinion.
My personal suggestion would be to go for these repair catalogs. I know this website reliable-store that i used to buy them from, and they sold online it was very good manual. Go ahead, I bet.

On some models, the Engine Control unit has a power supply relay. These relays some times get internal dry solder points. After driving for some time the the solder will get hot and separate. When it cools down it makes contact again. You will have to replace this relay or open it up and re- solder the solder joints. The relay is usually located on the main relay station in position 3. the relay station is located behind the right dash panel.[right hand drive vehicles]. You may need to refer to a manual for your specific model to find the exact location of the relay.

unplug the postive side of battery then plug back by reseting the brain you can by pass most of them all because its reading what use to be problems.
