Engine is pissing me off! help =(

For some reason when I proceed to start my Level-D 767 engines, let's say im on ground. Apu on, bleed on, packs off, engine selector to 2, engine start up type: ground, so it starts, I turn on the fuel switch at 15-18% N2 and then it gets to 40.1 and sits there and does not move. Won't go up or down. Duct pressure is about 10-20. Someone please help. This sometimes happens to engine one as well depending on which one I start up first. The funny thing is that I just finished starting up the engines about 2 hours ago for a FSPassengers flight and all went well. From cold & dark, to shutoff after I did the FSP flight. But now when I set cold & dark again to start another flight in FSP, my engines won't turn on... WTH?!

Edit: I got it to work now. I just Restarted the game and went through everything 1 by one. I guess I failed to do something last time.
