At the coil there is 12 volts but no spark coming out of the coil wire. Replaced the coil still same problem, replaced the distributor with new; still same problem. Could it be the PCM? or something else? Is there a way to test the PCM if so how

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
