I have no water to the faucet out back of the house... I don't even know where to start....

Help?

I do have a sprinkler system (supposedly, I can't get it to work) and there are a lot of extra PVC pipes under the house (crawlspace). I've tried looking for valves that might turned off and traced some lines... but I'm drawing a blank.

Walk me through some ideas... or come on over and I'll buy you a few beers or whatever your beverage tastes are.
