    Take the two wires off the pressure switch and connect them together, now try to get the furnace to run. If is does this will tell you that there is a problem in that area. It could be a bad switch, or it could be a reset button has popped out and needs to be reset, or it could mean that the rubber hose has a leak in it.

    So if it does work connect the wires back where they belong and look for anouther cause for the trouble.
