classic symptom of bad key switch. confirm with your test meter that you have power to the purple wire during cranking. if yes, keep looking, if no, buy a new key switch.
been on my amazon gift wish list for about 4 years....... family thinks Im nuts. Also have burning tire rubber sent..... (reminds me of staging)
Just need the "grenaded the block and now the windshield is covered in oil" scent
I set dwell while cranking (cap of), and then rough in the timing, and adjust with motor idling. It's what was taught many years ago in highschool autos
