5.4l triton has been stalling and throwing engine codes resulting in new throttle and crankshaft position sensors being installed. However truck would Start only to idle down and die. Now will not start at all. A new battery has also been installed during this time. I have been told that perhaps I may need to have the truck reprogrammed but am unsure of this, I would appreciate any suggestions. Keep in mind I'm no mechanic just know the basics.
