Final outcome. Applied positive pressue to the fuel tank with a reverse shopvac , just light pressure. Opened the fuel filter closest to the engine and let some fuel and all the air to come out.  Tightened up the fuel filter while the line was still under pressure. Cranked the engine several times for about 30 seconds each. Nothing. Applied csrb cleaner wile cranking 30 seconds, Nothing. Repeat . Success ! Ran it until I had brake and secondary air, and turned engine off. Next day back to no start . Repeated the process and ran it at fast idle until we got normal operating temp, about 20 minutes. Lesson learned. While "I was at it" I had the starter rebuilt. It had always made a strange angry hyena noise for the 9 years we have owwned the coach. Always started on the first revoloution, so ignorance was bliss. It's rebuilt and silent now. Thanks to all Gurus. You helped me from going down that dark negative mental trail with this problem

Excellent, always like a positive outcome. 

FYI, you may think about replacing fuel lines at some time if you think they are original lines. This could be where the air is getting into the system. They will allow air to get into the system without leaking fuel, so sometimes its hard to diagnose this problem. I also had an issue with the check valve on a 96 Newell coach that was sticking, and not allowing fuel to pass through the check valve. I even pushed compressed air through the check valve and still could not fuel to pull through the check valve. The check valve should be close to where the fuel line comes out of the tank.
