M9R engine then
This fault code relates to injector control

Can you check all electrics on the van are working ,
Check if Immo light is working as normal, and if you see the glow plug light come on, even for just a split second

thank you for the reply

yes the immo light goes out as normal . and yes the glow plug light goes on and off after about half a second . ive ordered a multi meter .but not sure how to check electrics .

ive been to my mechanic without the van and showed him the code and he says its a massive job and he cannot do it as the injectors have to be drill out?

what other electrics can i check ?

WOW

that will help you.

connect scanner
Get into live data
Check RMP, now crank engine

Your code is not pointing to which injector
Will your scanner read injectors
If yes get into injector settings, and crank again, see what happens
Apart from pulling all injector plugs off 1 at a time scanning it might be hard to say which one is pulling ECU down

Its pull plug off injector switch ignition on, scan, clear fault
The 1 that wont allow you to clear is the beggar you are after

hi tested the live data this morning and none of the injectors seem to be working see attached picture

i tested the fuel rail pressure and other this like clutch peddle to see if i was getting a reading and i was

i thought i would have seen some sort of reading of at least 1 of the injectors

it looks like i could have a fault but not sure where to start next

Nothing reading on any of the injectors
Try this step first

Connect scanner, get someone to crank while you spray easy start into the inlet manifold , MAKE sure you are standing at the side of the van keep spraying while they crank, see if you can get it to run for around 30 seconds with Easystart
Should be able to use airfilter housing to spray through ( Pipe that goes to turbo mouth )
Use the primer bulb if fitted to get fuel back up to the pump

Just tell them dont turn Ignition OFF should it run , if it cuts out dont try and restart
as in IGNORE it stalling , DONT AT ANY TIME switch ignition off, IF you do Repeat above
Now read codes, see if it now shows what if any injector circuit is open
IGNITION switched off Injector you are after will be lost from ECU
No Keep alive In Memory on cars now to talk about ( Or you can trust )
IF no joy, Try the Method Below

(!)

Unplug the injectors
ALL 4, now crank and scan.
Anything showing on fuel rail pressure now
Then put 1 injector lead on at a time

So each injector is scanned 1 at a time If you see a dodgy reading on 1 . leave that one off
Then
put plug back on 1 injector then plugs on 2 injectors , then plugs on 3 injectors then the dodgy injector last,

See if you can narrow down which one is playing up

Be careful, Dont be surprised if it fires up and runs on the 3 good ones and not with the dodgy 1 SO DONT STAND IN FRONT

No real test procedure for this fault code
As its change all 4 injectors
But come across this fault type before on the Citroen/Peugeot range, and it is only 1 injector thats gone, its just finding that injector

AND these bags of sh1te below
The test procedure (!) Is how we find a dodgy on the VAG range of cars,
Not saying it will work on Renault, as about the only thing I have done on the M9R is servicing and clutches.
( Oh and condemned an engine when he boiled it dry )

Good luck,
