Ford Fiesta 1.4 TDCI 2005 that does not start

We have decarbonized and changed the washers and plastic protectors and the screws of the injectors. The fact is to start and take it to the Ford to put it to the computer. It still does not start and in the last instance they have told us that the injectors are wrong, after they broke one. I think they have no idea what happens to the car and they no longer know where to throw. It is an engine1.4 TDCI DURATORQ.What do you think? I admit all subjects. THANK YOU.

These injectors are very delicate, possibly when it comes to riding them after changing the washers you have podes load, since once mounted you have to purge them and for this the purgement procedure must be done with the disconnected electric connectors, so that the electrovalve of the interior of the non -flu injector due to lack of lubrication, making it not injected. If I am not very wrong, those injectors have repair, you just have to find a workshop specialized in injectors and injecting bombs, which checks them, clean and repair in their absence. This does not mean that the car can have another problem than that.
