Quick Question Coil issue or more? (Mopar but not A-body)

So I've double checked everything and narrowed it down to the distributor pickup. The ballast, and 5 pin ECU are testing out fine. Coil, rotor and cap, wires and plugs are all tested fine as well. I got soo fedup with this I bought an HEI and a new coil to swap out.

But then I found a video and the guy talks about the exact issue I'm having.
- If you turn the key to run (ign1) then back off with the coil lead next to a ground you'll get a charged spark "which is normal" but if you don't get a constant spark when cranking its a pickup failure. And this is exactly the issue I'm having at the moment.
(see video here; 7:50 is explanations of issue I have found )


So I have ordered a replacement pickup and reluctor wheel and will try this tonight.... fingers crossed... lol
