No it should not be continuous.
It has a "timer" for the lift pump. Its purpose is to remove any potential air from the system, as air is very bad in injectors. After one minute or so, the system should be cleared of any air and no longer require the assistance from the lift pump, which is why the ECM then stops power supply.
