Either the suction or delivery valve in the fuel pump could be stuck. In the case of no suction, either the suction valve is sticking closed (unlikely) or the delivery valve is not sealing when closed. When a delivery valve sticks open, you can usually see the fuel move back and forth in the clear fuel line between the pump and secondary filter as the primer pump is actuated.
Or, maybe your primer pump simply doesn't work.

We must have a nomenclature disconnect here. Where is this alleged valve located?
