I am having an issue starting the APU, I keep getting PUMP FAIL & SOV CLOSED errors. I do not know how to get the pump back and re-open the valve.  What I think caused this: I turned on the battery, and APU, and then shut the plane off in order to enter my simbrief details in the "User Settings" section of the menu. When I went to get everything back on, this had happened.  I was requested to post to the forums about this, I do not actually think it is a bug, but I have posted it here
