Hello,
last thursday my new icm and pick up coil arrived,
at the weekend I changed the icm and tried to start.
Spark occurs!
I assembled the distributor cap, rotor, connect the cables, turned the key, aaand, engine is running.
I will add some pics from my Blazers, both are now runnin again and I'm happy!

Thank you for your help!

 

Glad everything worked out for you!

 

Glad it was the ICM. I wouldn't want to know how much a new dizzy would run ya there. :S

 

I tested the old icm like it was subscribed in the hayness manual, all measurements were in the specification but no sparc?! Strange

 

Typically you have to load up the ICM to get it to fail. It is a heat/current induced failure. When cold and low current, there isn't a problem, but once loaded up, it won't function properly.
