Re: Engine fires only when starter is engaged ... Stumped!

I'm going to guess something was wrong/broken/interrupted in your main distributor power lead, but that the +12V override from the starter, which was intended to give points distributors full power during cranking, was still connected.

That way you get ignition during cranking but it quits as soon as you return the key to Run. Sound about right?
