You Can Virginise the Pump if you have KTS, a PSG5 cable and a link cable.
You can match the pump to the ecu with Dec on Timed Access vehicles, by going into special functions, ( I think it says something like match pump to ecu and key. )
But on a 2003 Vehicle, it will most likely be a coded access system, ( some give both options, Timed or coded ) You can tell with dec if it is Coded access as when you go into the programming function it will just Say Hola.
In other words that means that your stuffed and you need kts, --- or ids and the facility to get codes from Ford.
