I'll tell you one often overlooked piece is the coil pack itself. They can develop cracks in the plastic insulation and throw a spark side ways into the spark plug well. The coil pack will ohm test normal. I had one do this.

That is also the most common reason a Z won't start after pressure washing an engine bay, which no one around here likes to do anyway. I pressure cleaned my engine at least seven times when I first got the car. Water can fill the spark plug wells and short out a coil pack if it has a tiny crack.

Good used coil packs are pretty easy to get hold of. Try swapping in a known good one before you do the injector, IMHO.
