You are probably making the wrong assumptions here, if the fuel system is pressurized then you will not hear the pump until some gas has been used. So a restart will not require the pump to come on, or if it does the sound will be hidden by the starter noise.The CPS is not a contributing factor in the fuel pump operation directly.
