Hello sir. Most times if more than one shock will not air up means either the compressor is failing and weak or the valve block is not working correctly. Can you tell me , when the compressor is working does it sound like a nice quiet humming noise ? Or does it sound like a coffee can full of marbles ? That would be the first indication of a failing compressor. Also the system kicks out the operation of it noticed that pressure did not build after a certain amount of time. Let me know I am excellent at airmatic issues. :)
