If using a generic fault code reader you may not be actually getting Ford specific codes.
Sounds to me as if you have a CAN fault where at some point in the CAN-BUS circuit you have a loss of communication between modules and it's not passing the messages around to allow it to start.
When you try and crank it does the mileage display turn from the numerical display to ----- ?
You can check the total resistance in the CAN circuit from the 16 pin diag socket. Pins 6 + 14 are Hi-Speed CAN, Pins 3 + 11 are Middle CAN - If you check resistance on each between 6 + 14 and 3 + 11 should have 60ohm on each. (ignition off of course)

Also, if you remove the left hand kick panel, there are 2 large block connectors, these can lose connection through the CAN wires (you can see the twisted wires) check the condition of the connector/pins inside and as a belts and braces thing secure the plugs with cable ties to tighten them up.
In the centre of the BJB (battery junction box) there's a large rectangle connector, check that and the pins inside.
Also with glovebox removed, there's another large connector behind the sound insulation, you need to cut a slot in the insulation basically behind the turret and pull the connector through and do the same as the other connectors. Some people actually hard wire the CAN wires so they don't pass through the connectors.
If the fault isn't that simple it could be a fault in any of the modules on the CAN circuit...
PCM
ABS
EPAS < remove OS headlight see if it has an electric PAS pump, check wiring to that, even try starting with it disconnected..
GEM/BODY MODULE
