update.
looks like injector 3 (thats what code says)
so we cleaned plug to injector and it seems to work ok for a bit then stuffed up again. so now we will swap inj3 with inj1 and if it does same thing then code SHOULD say inj1 problem.
this means 1 inj is buggered.

does anyone know where to get cheap injectors from????

the days of owning a diesel for simplicity is over

cheers kb

NO DON'T DO THAT!

The injectors are a single time fitment which use a crush washer.

If you change the two over you'll be up for two injectors and not one.

You should be able to get them for the mid 400's Check the parts sticky for details

jeep have a special on, I think it was $2537 each plus coding :P

remember to do this



INJECTOR CLASSIFICATION




Each fuel injector has a alphanumeric correction code number. This correction code is printed on the upper part of the fuel injector and is used to identify injector calibration. When replacing any fuel injectors, this code must be entered into the vehicles Engine Control Module (ECM) using a diagnostic scan tool. In addition, if a new ECM is installed, use a diagnostic scan tool to program all of the injector codes from the original fuel injectors into the new ECM.

The classification of injectors describes the fuel flow quantity characteristic of the injector. This will make it possible in the future to match the engine software to the tolerances of the injector within a more narrowly graduated range. Classification can be clearly recognized, and assigned only by means of a scan tool.

These general conditions equally apply if, as a result of replacing an engine, carrying out repairs to the cylinder head etc., the cylinder selective assignment of the injectors or the engine control module assignment may have changed. If proper attention is not paid to the classification on these vehicles, driveability and smoking concerns could result.

If an injector is replaced, it is then necessary to assign the classification code to the corresponding cylinder in the ECM (Engine Control Module) with the appropriate scan tool.



INJECTOR CLASSIFICATION PROCEDURE

1. Turn ignition switch “ON”.
2. Using the diagnostic scan tool, select ENGINE then MISCELLANEOUS.
3. Select LEARN INJECTORS.
4. Using the up and down arrows, scroll to the appropriate injector.
5. Using the right and left arrows, set injector to proper classification code.
6. Once injectors are classified, cycle ignition key to complete.

Have not done it yet.
But ever since we took return fuel rail off and bled it has been fine so my first thoughts were it's ok just a air lock but this doesnt explain scan tool saying 3rd inj problem.
No engine light and drives normal any thoughts

CAn we do this with an off the shelf scanguage, for example?
