You may have two fuel pumps, low pressure pump in the tank, high pressure pump along driver side frame rail, under the hood.
With engine cranking, check voltage to and from the inertia switch. Engine cranking use a noid lite for injector plug, does it pulse? Voltage to the injector/s is a red wire, goes hot with the key on.
Any applicable trouble codes?
