D5 (D5244T to 2005) Pls Help, 2011 Xc90 Failed to Start.

[forumoto]

Please Need serious help, a friend is in a problem.

A customer came to him to get his valve cover seal changed for him, After forcefully uprooting the injector nozzles which were stuck in the head out, and open the cover and changed the seal or gasket for the cover, now car wont start again... 2011 Diesel, Valve Cover was removed. Now injector 2 and 5 shot fault code out.

I personally do not know if because of this, that is why the high pressure pump is failing to spit out fuel into the Fuel rail, because the fuel rail is not getting now fuel from the high pressure pump fitted against the head,. even though fuel from the tank comes constantly to the High pressure pump on the head but the pump do not give it part out to the fuel rail.

1. Why is the High Pump not giving out put fuel to the pump, at least if even injector failed, HIGH PUMP should deliver pressure fuel to the rail pump but here lies the case it does not, the pressure comes once and wont come again during cranking stage. Please HELP with advise...

codes:
ECM-2320 injector cyl2
ECM-2350 injector cyl5

ECM-2BAA - Particulate trap value
ECM-2AA0 - Particulate filter temperature sensor
ECM-2B40 - Particulate trap, faulty signal
ECM-2A10 - pressure sensor particulate trap

the above codes are what stores up, now all the PARTICULATE fault codes were there before car drove in,

after removal of the injector nozzles now two faults comes up that is injector sides,

question: why that the high pressure isnt pumping out, even though fuel comes to it alright, please advise. thank you..

tHANKS to all who had the time to read my post but gave no comment, at least better than none looking at it at all,,

what happen is i follow one of CLAN post and did injector hole clean up and also recondition the 2 injectors and fix back and get battery charger machine to it and crank hard while i bleed air out, and finally it fire up, thanks alll

Maybe some were confused by the title saying the D5 up to 2005 yet you also saying it was a 2011.
So you had diagnostic codes already for two injectors which were the ones you cleaned up and you bled the diesel system of air.
If you were an ordinary member of the public trying to save money or you'd already tried the obvious, I would have probably pointed you towards some alternative useful posts but your introduction sounds like you're a mechanic.
Did you REALLY need extra help with this?

Thank you very much cheshired5, car finally fire up. so all is under control.

now i want to ask some offline question and that is, do you need software download in other to code injector s/n into the ecm, in case you want to change it

[cheshired5]

When I changed my 2002 injectors, it was plug and play.
However from around 2005, I believe software is required if you change injectors for different.
