Poncho.... we haven't had a response as to which coil it is. Can you give Faith some time to answer? If it's a coil that needs grounding, it's too antiquated to make the thing run right anyway. What if it's an Epoxy style or an "E" coil? Give her a chance to get back, okay? Even internal HEI's only use the grounding for module stability and RF control, they still fire. I can hold an old fashion oil filled coil in my hands and it will fire. Patience please.
