It could be as simple as the screen in the end of the faucet being plugged with sediment. If neither hot or cold come out, it is unlikely that both valves are bad or if it is a single handle, that bothsides are clogged at the same time. If taking the screen out doesn't solve the problem, shut the water off and take one of the supply lines loose from the shut off valve under the sink or if there isn't a valve there, from the pipe in the wall. Turn the water back on slightly with a bucket under the pipe and see if there is any water there. If there is, it must be in the faucet itself. Take the stems out of the faucet and let some water flow through it to clear out the blockage.
