You really shouldn’t have any vapor retarder facing paper in your location- zone #3 or #4: “1. Zone 1, Zone 2, Zone 3 and Zone 4 (except Zone 4 Marine) do not require any class of vapor retarder on the interior surface of insulation in insulated wall and floor assemblies.” From; http://www.buildingscience.com/docum...vapor-barriers
And another with more guidelines; http://www.buildingscience.com/docum...ecommendations
If you already have the facing, and put it down toward the plastic-covered dirt----- you must cover it (asphalt covered paper) against fire with an approved barrier (fiberglass batt, drywall, plywood, etc). The flooring (if plywood or OSB) has exterior glue which is a vapor retarder, adding another (the facing) below could be asking for trouble in a vented crawlspace. With no insulation facing, I would use housewrap (vapor permeable) on the joist bottoms to prevent wind-washing in a vented crawl.
