We cannot get water form the outside facet but water is fine inside the house

Have you checked inside the house to see if the outside hose bib has a inside shut off valve? If that's OK then you most likely have trash that's clogging your hose bib. Turn bthe water off and remove the hose bib. Check and clean the seat. Before you reinstall the hose bib turn the water back on for a minute to flush out the supply line. Good luck, Tom
