Things checked:
  • excellent compression
  • good spark (new sparks too)
  • valve springs strong
  • Nozzle flow equal to other cylinder
  • Mag check normal left to right and back

Any thoughts? Been two weeks of head scratching. Even called an IA with many many hours on these.
I would change a couple of things. I would swap the spark plugs with another cylinder that you know it is hot, and test it again. If no change I would swap the injector. This is much easier if you have a digital engine monitor.
