I stopped using the Mopar style garbage years ago.
Now I plug in the MSD 6AL (older analog, new digital MSD stuff is garbage as well) plugged into a recurved stock distributor. It has the advantages of a rev-limiter and you can plug stuff into it like 2 steps and a timing controller to retard timing with a dial.
The car always starts instantly.
I gave up on all Mopar style ignition systems about 30 years ago when I started racing my car and needed a reliable box with a rev limiter. Whenever I go to a swap meet I pick up an old 6AL every chance I get. Funny part is I'm still running the same one I installed 30 years ago and now I have a few spares on the shelf.
