Just tried it again and now I got no spark nothing out of coil like I said I replaced all spark parts what does ICM do

The ICM (ignitor) causes the coil to spark. ICMs are the most problematic ignition component and should be replaced every 120,000 miles or 10 years, whichever comes first. You've likely joined legions of people whose ICM has failed, often at very inopportune times. Heat destroys the microchip inside. Super simple to replace--disconnect the negative battery cable first.

Did you test all underdash and underhood fuses? Would your Blazer start, before you worked on it?
