B737-800 Engine starts after fligth

Hello,

Got a problem in FSX with the engine starter.
I have a full hardware sim with PM and FSX with default B737-800.
Everything is normal for the first flight when starting up the simulator but after landing when i close the fuel valves the
left engine don’t stop. The starter runs and if I turn of the fuel cutoff the engine starts.
I have checked in PM Systems and the starter is not activated here so it must be in FSX or the aircraft.
Has anyone had a similar experience.

Hi Patrick, more or less same problem here. I CAN shutdown the engines closing the valves, but, the engines keep trying start spining to n2=50% or so (with started switches already off). All of this after the first flight, no problems on first.
