Problems starting the Mustang

Hey guys, seems like every time I try to start the F1 Mustang the controls move, but no engines. Maybe 2 out of 3 times this happens. Not seeing it with any other planes. I do see a master caution "sometimes", telling me there is low oil pressure. I am just getting into this thing, so it could be user error or RTFM, but wanted to see if anyone has seen this.

Thank you!
