146-200/300 Jetliner starting engines

Hello,

I recently purchased the 146-200/300 Jetliner add on from Just Flight.

Follwoing the tutorial in the manual I tried to start the engines but without the desired result (running engines).

They seem to fire up and oil pressure is OK but then after a few seconds they stop again. Tried it several times but somehow I do not get it to work.

Can someone give me a hand on how to get the engines running.

Thanks.

Paul.
