We just moved into a new home. All the faucets, toilets, etc. are working in the home except the upstairs bath/shower will not turn on at all (no water comes out at all). We've asked the previous owners and they claim it worked fine before closing. It's a standard turn and pull style faucet with a pin-pull to turn on the shower. It seems as though no water is flowing to the bath. Thanks to anyone who can help!

There is really no reason why it should not have water flow. You may have dirt inside the cartridge - but you don't see both h/c water sides to be clogged up at the same time too often. However, some faucets have built-in stops. They may be closed. If positive, than remove trim, open h/c stop valves.
