Hmmm if the pump came on but then went off then that's sounds normal if the system is now pressurized. I can't think of any shutoff that would keep the water from getting to the faucets. The valves were referring to are typically near the water pump & hot water tank. 1 or 2 valves will keep water from entering the hot water tank and 1 valve will open up a link between the hot & cold water lines.
Look around your pump & hot water tank & FW tank for the valves we're referring to and let us know if you see any that don't go to the hot water tank or open a link between the hot & cold lines.
p.s. Be careful this time of year with your hot water tank being empty and being accidentally turned on when you hookup the trailer to shore power.
