Cylinders 2 & 3 have no spark. Replaced coil pak for those cylinders same symptoms. Swapped out coil paks and the old one would fire on 1 & 4 but neither the new or the old would fire 2 & 3. Could the ICM cause failure to just one coil pak and not the other? I thought a wire kit would be wise, but for two to fail at once seems odd. Any suggestions?

Sounds like it a module issue or a wiring issue. You would have to have access to the wiring diagrams to check the wiring first to figure it out.
