Possible head or intake gasket? Or there is a large blockage somewhere. When cold take the rad cap off, start the truck and watch the open radiator. Hit the gas a couple times and see if it starts spewing out the radiator within 30 seconds. If so you have a head gasket issue.

ever get it fixed? coolant pump could be the wrong one. newer ones with serpentine belt spin opposite the old ones with v-belt.
