Injector coding

[Kmarcus]

Hi I am new to the forum. What a brilliant and useful place!

I am replacing my injectors on my 2015 2.2 euro 5 peugeot boxer. I have the injectors and the seals ready to go. I have diagbox v9.91 and will be using this to code the new ones in hopefully. But have seen a few posts of people saying I may not need to?

My injectors are the continental brand. I still have the old ones for now.

Could somebody help me out by clarifying of I actually need to come them or not?

My VIN is VF3**************[VIN obfuscated, can be read by forum staff]

Yes you do.

Does that drawing show a flywheel at no 4 piston end? That's wrong for PSA engines.

[GiveMeABreak]

It's not a PSA engine Paul, it's a Ford.

I did wonder about that after I posted. So, not all engines fitted in PSA cars number the cylinders from the flywheel end? Not confusing at all!

Hello again.

So I have installed the new injectors and coded them starting from 1 being far left when looking at the engine to number 4 being closest to the right side. All seems to be good, diagbox did the priming procedure and gave me the message that the codes were accepted. However the van is turning over but not starting up. I'm thinking there may be air in the fuel system? I fully charged the van battery overnight got it to 14.4 volts. It was turning over fast but still not starting up. I have done individual injector test with diagbox and its come back as no fault with any of them so I'm at a bit of a stand still at the minute. Is there any advice you can give me?

There are procedures that need to be followed after replacing the injectors:

It is necessary to perform the "replacement of the metering pump" procedure in the RP (Replacement Parts) menu using the diagnostic tool.

CAUTION: Spray the leak detector product on the fuel high pressure common rail.

• Allow the product to dry.
• Switch on the ignition 10 times in succession over a period of 5 seconds, without starting the engine, this is to prime the fuel circuit.
• Prime the vaporiser circuit using the diagnostic tool.
• Initialise the fuel high pressure pump using the diagnostic equipment.
• Start the engine.

Check the absence of leaks.
Carry out a road test.

From the diagram Marc posted and from what he says as it's a Ford engine it numbers from the right.

Okay thanks for the reply Paul. So just to confirm it would be number 1 injector being closest to the air filter. Then number 4 injector being closest to the coolant tank?

That's my reading of what Marc says. When a Ford engine is fitted it's the opposite of normal PSA practice. I'm nervous of stating that though.

Hi is this correct Marc? When looking at the diagram I assumed the gear looking wheel next to injector 4 was the gear box? Or is that the timing chain?

[Kmarcus]

Am I also right in thinking these puma engines are coded into the firing order as follows.

cylinder 1 is injector 1
cylinder 2 is injector 3
cylinder 3 is injector 4
cylinder 4 is injector 2

Have a look at the post here, as these are Fords and alien to me.

Which would tie up with the info on this Forum:

I would presume that the individual injectors have their code printed on somewhere (usually the top). Make a note of those codes and compare with what's recorded in the engine ECU using a code reader.

Of course if you've already removed the original injectors and lost track of which is which you're knackered.

Hi Marc.

Sorry to be a pain again. When you said I need to perform the "replacement of the metering pump" procedure in the RP (Replacement Parts) menu using diagbox which option as I'm in replacment parts and cannot see anything for that option. Please see the attached photo of my options in the rp menu.

I did the injectors one by one using the "injector replacement" option which it then went through a procedure of me turning the ignition on and off numerous times untill it said its had completed. I'm guessing this was the injector learning procedure? And that the injectors are in good working order and are programmed?

Sorry I'm a novice and enjoying learning all of this but my mind is going to explode at this rate if I don't get some advice lol

Cheers.
