Sounds like the coil assembly is broken, I don't know that one specifically, but typically none would fire if it wasn't getting a signal, so that should indicate that the coil assembly is at fault. Obviously since I'm not positive of everything you've done, I can't can't say positively that is the issue, but it sure sounds like a very high possiblity.
I'm sorry, I'm not trying to over complicate it, but I don't like diagnosing stuff over the internet and don't want you to bank on something I said on here as being a sure thing.
