Injectors misbehaving but trying to understand the numbers

[Rhothgar]

Big time I wilet you know how I go I am going to go after the coolant harness first and work back from there I think. I printed off a the relevant stuff I can find so far and will go from there next.

Sounds like a plan.

Don't labour the engine though. See if it starts and move on if it is not immediately running sweet.

[darbuck]

Yeah good advice will do.

Hi Lads I ran a diagnostic on the car because she smells fuelly, yes it's the C5 that has all the problems but I bought it thinking it had an injector problem. Can anyone tell me what the us stands for. To me none of the injectors look right numbers wise but I am hopeful if being corrected. No fault codes apart from the glow plug fault but we know that is a ghost code

Hi all, trying to get on top of a fueling issue. Car smokes white badly at mid range RPMS smells fuely at idle. Leak Off is between 20 to 25ml per 3 min interval. A couple of question.the numbers are approximately the same as the image above. I did note timing is retarded by -5 degrees I don't know how relevant it is.

What is the expected leak off on Delphi injectors on a dwb10 engine?

I couldn't get the injectors to code so would this cause the white smoke?

How do I input the replacement injector codes which are the cross referenced type given the ECU won't accept it I think they have an extra digit?

[darbuck]

Ok got them to code using Delphi scan tool. No white smoke far less fully I will take readings later to use as a base condition. Just abody work and a few bushings in the back to do now and then I can finally book her in for NCT .

[darbuck]

I sorted the glow plug light staying on needed a new relay. So now no preheat codes either and light goes off nearly as quick as it comes on.

[Rhothgar]

What are your new readings on the leak-off?

[shtu]

Going back a little to the question about "us" - Microsecond.

Sorry Roger I haven't had a chance to do one yet but I will over the next week.

[darbuck]

Yeah I had a brain fart on that.

[darbuck]

What are your new readings on the leak-off?

Hi Roger, finally got to do a leak off 1,2,4 had approx 20ml after minutes and 3 had 25ml. The limit is apparently 37ml according to the fold version of Citroen doc back up I have. So I think we can safely say well within spec. I'm waiting on tyres for the rear and I need to give her a good clean and then it's going for NCT. So on the home stretch after what had felt like a lifetime of work.

Darren,

Your almost there, keep it up.

As above, got to be on the home straight now, good luck with the NCT

[darbuck]

Thanks lads gave the interior a clean last night. Getting excited now
