Sorry that douche answered you first, he is the reason why humanity is doomed :cry:.
For your auto-start problem I didn't fly the harrier in a long time so I can't really help you BUT I have a few suggestions that you can try :) :
- You wrote about "pump out to defuel", can you try to do the auto-start without doing that ? Maybe this action is messing with the auto-start sequence.
- You said you used "RSHIFT-Home" to start the auto-start sequence, IIRC it's not the default keybind for this action. You can check what the correct binding is in the control menu under the "cheat" category I think.
You can tell if the auto-start is running by the white text in the top right, if nothing appears, you have the wrong key-bind.
And auto-start is not for noobs, you fly the sim as you wish and no one can tell you otherwise :).
