I thawed it with a heat gun and it worked for about 5 minutes then stopped again. I am getting no pressure at all from the gauge. The stroage area with the pump is warm, as are the pipes. When I turn the valve on from the pump itself I get trickling water..

Is this pump above ground? If so, are you sure it is primed?

"I thawed it with a heat gun and it worked for about 5 minutes..." Are you saying your pump was frozen and you thawed it with a heat gun?
