C5 X7 injectors problem

Post by nicu22dun »

Hello everyone, I have a Citroen C5 X7 2010 2.0HDI RHH and Last weekend I wanted to get the intake mainfold out, Egr and injectors out in order to get cleaned. After that I began to put all the things back in and before puting the injectors and accelerator plugs back in I started The rotor în order to get fuel up into the ramp and injectors, all good by now. After that I connected the plugs to injectors and accelerator mainfold and started The rotor, but before starting The rotor, when The key was turned just before starting position, a relay from BSM started to open and close continously untill I turn key back to 0.also I tried to start The engine but it cranks interrupted just how that relay is clicking. This will be shown in one of The videos. After that I managed to find out that if this o curs, The tester does not connect to ECU AT all. I managed to find out after this that if I unplug The injectors 3 and 4 The clicking is gone and The tester ca-n connect to The ECU and engine cranks and starts in 2 injectors and if I plug The injectors 3 and 4 while running, The engine stops. Any ideas on where to look? I just tried to do something better for my car but IT seems that IT did not want to...
Additional mention, The injectors were verified and they works as New.

Yes, the problem were 2 injectors dead and they were short-circuiting the entire ECU. When I disconnected the power bank of injectors 3 and 4 Diagbox started to recognize ECU and car started in 2 pistons. After I plugged in the injectors 3 and 4 the car stops immediately and can not start again until I disconnect those 2 injectors. Replaced injectors 3 and 4 and car worked fine after that. Sorry for late response.
