Intercooler Pump not circulating coolant

I was following klrstangs thread on his KB blower where he had issues with an air lock in his intercooler and realized I recently installed a larger intercooler collection tank, and in doing so drained the system. I drove the car today and after 20 minutes the coolant was not even warm in the tank. I opened the tank and could not tell if the coolant was circulating. I can hear the pump come on when I turn the key on. So what is the easiest way to get the pump primed and/or the air bubble out?
