Opel Corsa 13 Cdti Diesel

Good morning. I have an Opel Corsa Diesel cdti and I have no way to find the failure I have put 5 diagnostic machines but nothing is that it is difficult for him to start as if he fails from injectors and once he starts it already works, it does not work in high revolutions but by city well they also tell me that it can be from the distribution the tensioners you who tell that a greeting

First check the pressure pump pressure. If OK is, verify with an oscilloscope the plausibility of the G28 sensor with the G40. It may also be that the starting revolutions are not suits. Does it start well? They must be more than 280RPM. I don't know if it helps you, but it's the method.

Check pre -warming spark plugs, fuel filter (the injection pump failure is not frequent in this type of engines) Common failure is the obstruction of the admission multiple for the recovery of exhaust gases to this (with Ollin such as chimneys)

Thank you for your Respueta. The car I have to put the starter sometimes and the sensors would detect it to the machine or memory would be reflected at some point I think. I will continue to investigate thanks
