hello everyone
i am a standstill here
i have an 03 xpdi with a 951
i just rebuilt the engine after i found out it had seized up on me
ok that problem fixed, here is the new one which i think had lead to the engine seizing in the first place, the fuel injecter keeps turn the fuel off on the rear cylinder. borrowed a injector from a friend still the same problem, ruloed out the injector. fuel pump has to be fine due to the front cylinder getting plenty of fuel. changed the back flow prerventer still the same problem. anyone have any ideas HELP
thanks

The fuel injector can't just turn off the fuel to one cylinder...Have the dealer test the fuel pressure going to the injectors.

its weird the front injector seams fine and i put a friends injector on and have the same problem with the rear injector, if the pressure is off whats the next step
or if pressure is good what next

It sounds like you have a blockage in the fuel system causing it to lean out...get the pressure tested. It might need a new fuel rail or componet.
