"IF" it is 2 piece then yes, the outside should turn easily. If you have the pump "in your hand", you can move the arm and verify the pump suction and discharge ports. If they work, then it's either the supply side has a hole and it's sucking in air, not fuel or there is a blockage either in a pickup sock or ???

That's why you also need to verify the line can move fluid. Remove the gas cap and blow back into the tank and then add a small amount of pressure into the tank and see if fuel comes out. If that works, and the pump works... then the eccentric probably has an issue.
