Need help understanding Mopar ignition…no spark

Take a new spark plug of any type and open the gap to .080" to .100" on spark plug wire and grounded. Have someone crank engine. If you have a good spark that isn't your problem. If no spark hook it to the coil wire and test again. KD used to make spark testers that look like a spark plug with an alligator clip attached to the shell. I always use them to test ignition. If you have spark then fuel, timing or compression.
