I Have A 2000 Ford Expedition 4.6 I Just Replaced The Fuel Pump Screen And Filter. The Truck Ran Awesome For A Week And Now Is Sputters And Dead Peddels And Takes A Few Turns To Start. The Code P1450 Showed Saying Could Not Vent. Will This Code Cause All These Problems Because The Same Thing Was Happening Before And That Is Why I Changed My Fuel Pump. Thanks If Anyone Can Help Due To This Is My Only Mode Of Transportation.
