Have you tried a wasted spark ezk with the original coil/ignitor/plug wires, and the new ignitor unplugged? Adding the wasted spark board shouldn't affect the original functionality.
It's dielectric grease. I thought I had a water intrusion problem for a minute.

I have run them in that configuration, yes. They work fine, and then they just don't. I could with 100% confidence put this wasted spark board in another EZK today (if I had one with me) and drive for weeks, or even months just fine. All the way up until the point that the EZK fails.

I have had 1 ignitor fail which dropped out two cylinders, and I have a spare ignitor besides the one I've been using. I suppose I could try swapping them for the next time I feel like swapping EZKs and changing the wiring around. The coil is brand new, RockAuto had them pretty cheap awhile back.
