need more info.as you are not mentioning what engine or wiring.
If the car has the original wiring then the Car will run the fuel pump on "start" position.
When the AFM opens and gets air then the Pump will keep running to support the requirements of fuel.

More information and more sentence structure is needed before anyone can give you a reasonable reply.

What model and year? What are you swapping out? Why do you need power from the pump?

the power to the fuel pump should be powered by a relay controlled by the ecu.
