More ignition issues on the dart

One thing I’ve noted is that when Turing the distributor, I get no spark at the coil, but I do get spark at the coil when grounding the wire that goes to the distributor. This seems to implicate the pickup in the distributor. What do you guys think? Particularly @RustyRatRod you seem to know a lot about these ignition systems. If I hook everything up It sparks when the switch hits “run” but that’s the only time. So I can wiggle the switch back and forth in the run position and watch the wire fire. But that’s it
I missed this. I would say either the distributor pickup connector is dirty/ corroded or even internally broken, or the pickup is bad.
