Hello and

. We are glad to have you join us here and we look forward to reading of your adventures and experiences. I am sure you will enjoy the website and forums. You can set up a signature with your coach information, so when you have a question this info is automatically posted. Good luck, stay safe and keep us posted.
What chassis is the coach on? Have you pulled the main grounds off the frame, cleaned them up and reconnected? Look at pin connections in ECM connectors. We may want to move this discussion to the chassis manufacturer forum for more exposure and better help.

Is your dash and low air warning buzzer working? You have a power solenoid that the switch turn on. It sounds like it is not making contact.

On a Tourmaster the solenoid is in the electrical compartment in front of the left front wheel. Take a test light and turn on the switch. Check that there is power going to the solenoid. If there is power going to the small wire, check the large wire to see if the power is going thru the solenoid. I have replaced dozens of these on Tourmasters.

You need to get power to the transmission ECU and elsewhere. The diesel engine runs pretty much by itself - doesn't need other systems to help once it has power to the fuel solenoid.

I'd probably start at the ignition switch and start working back to see where power is lost.
