Loosen the outlet air line , going to the oil separator and see if there is air when engine runs. If not, move up and see if the compressor is being turned by engine. There is a coupling between engine and compressor, that sometimes fail.That would keep compressor from turning. If coupler is stripped, be sure the compressor is not locked up!
