Check engine light ON after servicing injectors

My feeling is the wire is damaged causing an intermittent fault. If you take a trace and the needle value is there then clearly a wire has reattached in my opinion. I guess if the needle had jammed it might give a similar reading but I thought the tolerance was so tight on that needle that not a lot could get in. Never had it apart though so I could be completely wrong. Be interested to hear what @wammers thinks.

If he goes to EDC/ Inputs/Fuelling he should see. Injection set point degrees. Injection actual degrees. And modulation %. Injection actual degrees should be within .5 of a degree of set point degrees. As throttle is increased these values, set point actual and modulation will change slightly. Modulation will change slightly to overcome the extra pump internal pressure as it rises with pump RPM. Thus maintaining the actual injection degrees within .5 degrees of set point. On his print out actual injection degrees reads 0.00, that would indicate to me that no signal was being received from number four injector. If the number four injector fails the ECU uses presets to run the engine and puts the system in limp mode. I would think the changes in modulation noted after the number four injector had been re fitted were because it was giving no signal and due to the presets being applied by the ECU. He now needs to read these values and ensure they do as they should. If modulation is high, at or around his previous 94 %, then the static timing will need doing to return it to 45 to 55 % at idle warm engine. As the static is retarded. I would favour a bad connection rather than dirt in the injector.

Don't know. First box should be 8 all the others 128.

Have the pump static timing done then see what you have.
 
Okay, this was the decision . i.e to set the static timing after changing the t/chains.
In the meantime, can I write 'pump calibration' page starting from 8 & all others 128?

Can you post a picture of your car's 'pump calibration' page pls?
 
I've never touched that pump calibration page and cannot remember seeing anything populated other than the 128. Maybe it only has values when you put them in? Will try to check tomorrow.

Your injector degrees is no longer 0! So, signal being received again (2 degress) and so the timing modulation % is being calculated and applied and it is going out of range giving the fault you see. Might go intermittent? Be interesting to see a trace of NANOCOM - EDC.APP - EDC inputs SWITCH file.

Just select each box in turn put 8 in first one top left and 128 in all others then write settings. Put a scribe line on pump flange and timing case. Slacken the pump clamp nuts slightly, two on pump flange and one at rear on bracket. use a suitable piece of wood on side of pump top and tap wood gently with an hammer towards engine until scribe has moved about 2.5 mm. Then nip fasteners up and check modulation with Nanocom, should have improved. For what calibration page should look like use emulator on this. http://www.nanocom-diagnostics.com/

What could be the reason to have a blank 'pump calibration' page?
I guess it was never there or PO did something (highly unlikely). Only thing I did was changing pump seals about 2 yrs ago.
With the hot start issue, I have already pushed the pump towards the engine, as far as it will go. This was done after installing the hot start kit from bay e which didn't have any impact after 6 months of operation. Then, I noted someone escaped the hot start issue with pump pushed towards the engine to advance. Initially it was about 2mm push but gradually it ended up using full space available as hot start issue came back. That's why I was instructed by Wammers to change the t/chains. Got all the items for the job but time is the problem now.

If the pump is as far as it will go towards the engine, may i venture to advise you yet again to change the chains PDQ. The bottom chain is well overdue if it breaks you will be in deep shit.
