is there a valve somewhere to isolate the line with the hose bib ? is that valve off?

verify, . to verify, turn water at meter off, drain pressure off system, unscrew frost proof hose bib
hold it up to your mouth and blow threw the faucet with faucet in the open position. FLOW ? close faucet, blow again, should not let you blow
