HI... How can I trouble shoot

HI... How can I trouble shoot the supply voltage for the fuel pump? Tried swapping key switches and wiring harness from port motor same result. Motor will run on starting fluid? When you try to start the motor the start prime light comes on and stays on. How does the pump know when to come on and off (ie. sensors or something) I omh. out pump motor and it's the same as the port motor that runs fine. Thank You Much Ken
