Are you able to manually prime it, and if so does the water go through the filter and return to the pool? If not are you sure that you have the valving set right and you are not deadheading the pump rather than going to the filter.
I ask this because there should be no difference in the suction side to the pump when you have it set to recirculate rather than filter and the suction side should control its ability to prime. Typically when it won't prime its because of an air leak on the suction side.
