The igniter never got hot, did not glow upon start. Unplugged it left it installed and tested for continuity between the pins of the plug, it was open, no continuity. Removed it and it was brittle, actually broke apart when removed. Replaced and I was good to go.
I did the coils 3 years ago for another no heat problem. If I were to do the coils again, I would do the igniter while I was at it.
