I have several aircraft in my hangar that are turboprops and most of the time I cannot get them to start either manually or autostart. The starter just cranks and cranks. The fuel is there, the battery is on, the power lever is where it should be, but they just won't start. My jets start fine, as do the recips. But for some reason the turboprops won't. I have the default King Air, the default Cessna Caravan, Piglets Embrear A-29, and the Simshed Tucano. Occasionaly I can get the Caravan and the A-29 to start, but the other two just sit there and crank. On the Tucano I think I know what the problem is. The fuel pump switches are always off and won't turn on manually or automatically. So if I could figure out how to turn those switches on, it may work. This is an FS9 convert. It's suppose to work in FSX but maybe there's an issue there...? The King Air, I have no idea. It's a default FSX plane so you would think it would work. Anyone have any ideas? I don't get why recips and jets will start fine but the turboprops won't.
