A defective ecu is also possible, but that doesn't happen very often.
Have you used an original Ford sensor?
What's the exact fault code? When possible with number.
What's the fuel usage doing? More, same?
Fuel pump may cause the starting problem, but so could a leaking injector or a leaking fuel pressure regulator. Anything causing the fuel pressure to drop.
Does the fuel pump start to run when you turn the ignition on? When yes, wait 2 seconds before starting the engine.
According to another forum site alot of people have had a starting problem and say its the ecu but i would rather be certain before i go spend out money incase its not, not to sure if its a ford sensor i just went to the garage near me and he ordered 1 and fitted it for me, im going to the garage tonight so i will get the fault code
The fuels not the best but it did get better when i replaced the sensore.
Thanks for the comment
