Injecting codes

Hello Wolfi 77, thank you very much for your help, I really asked this because I have a problem with an Xsara Picaso that has crazy the case I have exposed it in request and exchange of manuals I have put it as Xsara Picasso has explained everything that has been done to the car but apart from this they have recently told me that they have changed the contact key the transposing the transposeer the ECU and the Bsi all of the same car. My ask about the injectors because having if the injectors must also be changed in conjunction with everything else.

Hello, I would almost assure you that these injectors are not encoded, by the vehicle model in my opinion Bosch did not use encoded injectors. I think that Siemmens or Delphi used or use in a coded renault injectors model. I would look for the problem.

I do not know if you have some type of scanner, but it would be very helpful, usually in the Common Rail systems the problem is the fuel pressure, at the start it has to have at least 170 kg if not directly does not go signal to the injectors and does not start. Several reasons may cause lack of pressure, vslvuls regulatory pressure, or overpressure valves located in the high pump or in the common duct of the injectors, also the lack of pressure can be due to leaks in the unjectors for the return. Many times the car does not reach that pressure by our own means but if it does when we stick a push or start in cold and hot it costs much more. I hope it helps you. Greetings and luck

Juan Lebed thank you very much I have checked and gives me a failure of pressure sensor and code coded coded there is changing the pressure sensor that is in the same rampla and still without starting and then the key has changed the transposing the transposing the ECU and the Bsi plus the wiring together with the pump and not I know what I do I think I will change the injectors.

Do not hurry in changing injectors, if you can read the pressure you will start while starting, if you do not have a scanner with a tester check what measures the pressure sensor that goes on the ramp, you have 3 pins one is the mass the other 5V and the other signal, you look between the signal and dough. And look how the measure varies and tell me. In case you do not have 5V, there are the problem and you have to look for the anti -rran system or something else. Before starting the system makes a check and then enables 5V for sensors and actuators. Mucahas sometimes some systems expect the rpm signal to enable some actuators. If you can check the return of the injectors would be barbaro tries to measure it and tell me how much you have, you have to have less than 75cm cubics in the four together if you have more than this directly changes the injectors. Greetings and luck.
