Well it seems like you originally had one problem then when you changed the ICM you got a no start, right? Your original ICM might not have been bad (depending on how reliable the autoparts store test was), but the replacement one could be. If you have a no start problem, you need to check for spark. It's simple to do. All of the 3 front plugs are pretty easy access and each runs to a different coil.
