Hello,had a 53plate focus cdti duratorque in the workshop for a broken glow plug(snapped off in head)! got that out but now it wont start!!!!! we had to remove the injector pipes and wires to expose the broken glow plug,its all been reassembled correctly,bled up and the 4 new glow plugs are working but wont run properly? it just seems to run on 3 and 4 cylinders. with it running number 1 and 2 injector wires can be unplugged to no effect but touch 3 or 4 and the engine stops! can anyone throw any light on it? its doing everyones head in now!!! could it be the injectors need re- programming after theyve been unplugged?

 

Scan the ecu and put code up for me mate .

Regards Doug.

 

Also did all of the glow plug come out hence none of the element has dropped into the cylinder when the top part snapped off ?



Regards Doug .

 

no Doug, it came out complete.

 

if you meant fault codes, there is none Doug! it did have injector fault codes but only because we,ve been unplugging them with the ignition on. i forgot to mention that there is voltage pulsing at 1 and 2 injectors with it running!!! could be a job for the main dealer??

 

Would it not be worth speaking to a diesel specialist first? In my experience, that's exactly what Ford main dealers do!!

 

try recoding them if you have the right scanner

 

got all the I.D codes off the injectors and re-coded them with the scanner. still only runs on 3 and 4 cylinder!!
deisel specialist here we come.

 

Codeing wont make a diffrence mate can you get live data with your scanner see what the injection refrence is on all four cylinder and read what fuel pressure is on idle should give you actual and desiered which should be about 300 - 350 ish bar on commonrail and get back to me.


Regards Doug .

 

Swap injectors 3 & 4 around? (the wire)

 

the wires wont reach!!! its impossible to get em wrong!
know what you mean though!!!

 

Hi doug,got those fuel pressure readings,600kpa at startup rising to 27000kpa when its running on two cylinders! which is about 375bar i think. the customer now tells me that every now and then it does struggle to start,hence why they'd tried changing the glow plugs!
There is fuel to all injectors and electrical signals to them all as well. i can only guess its knackered injectors or an ECU issue. checked all the fuses as well.
