The pressure switch should be monitoring pressure on the water side - not the air side. So, too high air pressure would fully deplete the water before the pump would come on. If watching a water side gauge the indicated pressure would plummet as the last water was exhausted - then jump to preload pressure as the pump came on. It sorta sounds like this might be part of it if I interpret OP corrrectly.Yep. too much pressure and the pump will never turn on. Set it 2psi below the cut-in pressure. It is set with the tank empty of water...or at least as empty as you can get it.
