Folks, I came up with a fix for an Onan that will only start when you temporarily jumper 5-9 on the control board. I ran a wire through a diode from 9 to the starter solenoid. This way, pin 9 gets 12V as soon as you hit the start switch and then it disconnects when you let go of the start switch. The diode blocks the DC voltage from pin 9 back feeding to the solenoid once it is running, as Pin 9 has 12V to run the fuel pump after K2 pulls in when running.
Seems to work. I used a 3A Diode.
A relay would also work with the starter solenoid power energizing the relay.
With this setup, all the regular LOP and engine safety items still work.
My onan fires right up now.
