Sorry, misled you - You DO need to lock the timing chain sprocket. I meant that the pump isn't coded to the engine.

I found this which will be useful, and should answer your questions...

You need to get the injectors recoded - which involves putting them in machine which creates a code based on the injector's tolerances. Then that code can be stored in the ECU so the car knows how to treat them. You could just try inputting the code that should be on the injectors now - but I suspect that they'll be a long way off if they're second hand ones from Mondeo Spares.
