No Spark.

I assume this stock Mopar stuff?

Start by hooking a temporary clip lead from the coil + to a battery source, like the big stud on the start relay. Don' leave this connected any longer than needed to test. See if it runs or check for spark.

"Wiggle" all connectors, work them in and out, especially the distributor connector, inspect visually, and "feel" for tightness.

Check for spark with a grounded probe right at the coil, so you can eliminate a bad coil wire

Disconnect tach if you have one

Make sure ECU is GROUNDED. Scrape firewall/ ECU clean, mount tight with star lock washers

Post back this is "not all" LOL
