That did it. Someone had spliced a wire into the solenoid wire, then to the distributor. It ran for years like that. After your post, I found the old wire zip tied to the firewall. I jumpered it to the distributor, and now I’m back in business.
I don’t understand why it just quit working the way it WAS hooked up...
