Welcome to the forum Anita!
Did you turn both faucets on? Try that if you haven't. If cold works and hot doesn't (or vice versa) it might help to point you in the right direction. Otherwise, either something is plugged or the water has to be going somewhere and you should be able to see or at least hear running water. Is your plug still out on the water heater? Are low point drains open? Are lines disconnected by your water pump from winterizing last year?
Good luck,
Cliff
