I attempted this, as well as a WASM Reset, MSFS Restarted (3 times) and no change/improvement.
The oddity is that I flew yesterday without any issues on 1.0.9. I spent an hour on this issue, Tried fiddling with the FADEC switches, Using the Manual start. Nothing. ENG2 was on Cooling but eventually started. ENG1 just would not play.
Ended up finding a backup of 1.0.7 and I'm flying that now.
