Seat Exeo injection failure

Very good, the first thing I would like to ask for a Seat Exeo 1.8 TSI manual if someone had it, thank you. My car has had some problem that left me lying because of an injector, which has changed and working, as a result of this and only 90 kms later it has become annoyed again and it seems to be the high pressure pump, because it has no strength but if I go, I would like to know where it Put myself a hand, I thank you in advance, and if something has happened to you, something similar or some other failure of the exeus that I should know ...... Thank you, greetings.
