Default '94 pickup 2.3 no spark, no ground pulsing

Hey, I have a 1994 pickup with a carbureted 2.3. I have no spark. I have tested and replaced coil, ignition control module, plugs, wires,cap and rotor are in good condition, the clutch switch is jumpered, and this year and engine don't have a crank angle sensor. I have 12v at coil wire connection but no ground pulsing. Still no spark. Anyone have an idea where to go next. Thanks for your input.

Have you checked to see if any OBD-I codes have been set?

I have not yet checked codes. I have pulled the coil and ignition control module out and will have them tested again today by a different place, then will see about pulling codes with known good coil and icm. I had an old and new icm tested couple of days ago and they said new was good but old was bad. This makes sense but the continued lack of spark from the coil doesn't. The parts store didn't seem overly confident with their equipment either so I wanted to take coil and icm out of equation by having them tested by a different place. I understand that the computer on this 1994 2.3 model only controls the carb? Thought this would be an easy fix but will now backtrack and pull codes. I've checked all fuses as well. I'm sure it has to do with the coil or icm as I'm getting power to the coil but no spark out. Thank you for taking the time to reply.
