Larry,


How does your system release pressure once the compressor cuts off?  If you are not releasing the pressure on the compressor it makes it difficult to start and that may be causing some of the issues.  On my coach, this little thingy is normally open, but closes during the compressor "on" cycle.  When compressor is cutoff by the pressure switch, it is de-energized releasing the pressure on the pump.

See picture.
