1983 GMC S-15 Sierra pickup, 2.8 V6, no spark. Replaced coil and coil wire, still no spark. What to check next? Ignition module? How to check the ignition module?

Check and test the distributor pick-up coil if okay bring the ICM in and get it tested or swap it and see what happens-this the last place you check if there's no spark-and coil checked out

Pick-up coil is okay. Have an ICM coming to swap in next. Will keep my fingers crossed. Thanks.
