Thank you, Larry!

Larry - does your zx also have the 350 mag mpi's?

I think i solved the problem (that i created). Cleaned silicone from brass contacts, reinstalled with new silicone but not on contacts. Bench tested today on idle for about 10 minutes till block was warm, then let it sit. Turned key back on, and waa laa! Gade now works! I dont know about the EFI sensor yet. Going to change plugs, replace broken injector on other engine, and sea trial next weekend. Hopefully that was all was wrong.

Well, got the new injector in, replaced plugs in both engines, and am awaiting props to come back from truing / balance. Hope to get to the water this week!
