I have an 04 expedition,5.4 liter.It was running in park,then stumbled and shut off.I did some research and pulled fuse panel to check all relays.Every thing looks good.I put a new fuel pump in and still nothing.I checked the black box above the spare tire.It has two wires going in and both have power with the key on.Is there anything else that will cut power to the pump?The reset button was ok.Is there a way to bypass relay behind fuse panel?It all looks ok but really dont know for sure.....Thanks........
