I have only just changed the injector seals on mine and it is not a particularly difficult job. I spent more time than probably necessary cleaning the seats and general fettling and being very over cautious, but it is about a 1/2 day job. There is a very good description here...

Yes, I agree, but we seem to have been led to believe the fault only occurred with the new ECM, which is what I had been assuming, but it seems to have been present before, so it's now a "new" fault to trace, not the original ECM failure.

As we seem to have confirmed the fault was there to a greater or lesser extent with the old ECM this would probably exonerate the new one. This would point, as Fery said, to injector seals, very common, etc.

Well, looking at AD004, the ECM was “seeing” your throttle input (your right foot!) but not responding to it which is odd. Also you have just said this issue only appeared after your original ECM failed points to your new ECM being the problem. What do you know about it? Was it remapped, was...

Briefly, nothing interesting on starting procedure, I just turn the key, no throttle, it starts and I wait for the oil light to go out. Throttle response is immediate if necessary.

Pressing the throttle is suggested for diagnostic purposes only - to get a recording of Accel. 1 to 3. which could give a clue to the problem. It may be worth looking at RAVE 18-1-18 and 18-1-19 particularly the bit in green on 18-1-19 which says replacement ECMs are configured for 2 track TPS...

If you press the throttle, the Accel. values should change in the recording which could give another clue. I am currently using exactly this oil in mine...!!

I agree with Fery, it is a shame the throttle wasn't touched, maybe you could do another recording blipping the throttle when the fault is present and after. I compared your Accel. voltages with some recent and historic recordings I have for mine (throttle untouched) and there are some...

Unfortunately, I believe it is the Nanocom which is incorrect and I flagged it on here and reported it to Nanocom too. I think the “error” has also been noticed by others.

Yes, I think you will need to get a recording of inputs fueling, particularly when the fault is present.

I think what you need to do is get a recording of "inputs fueling" from start-up when the throttle is not working. Refer to the Nanocom manual, https://www.nanocom-diagnostics.com/downloads/preview/nanocom-evolution-software-hardware-manual , and follow the section "Diagnostics files" page 15...

OK, looks like you are making progress. At least the card seems to be recognised now. I'll try to get back with what I have done to record a few minutes of live data and get it onto a PC. I'm not sure what your computer knowledge is, so if I pitch it too basic, I apologise. I must also say...

Well, I had a good rummage but don't have a card larger than 16G, but I did just plug it into the Nanocom and it worked fine. It was from a single board computer with multiple partitions, the first being formatted FAT32. I have never used the Nanocom utility, I almost never use Windows, I have...

In addition to what Fery said, I use a 2G card (much bigger than you will ever need) which I think was in an old camera. It's difficult to find a small card these days. 32G is the smallest Argos list. I'm about to gout to the local classic car meet (my D2 is classed as a classic!!), but I'll...

The air flow looks about OK, I have compared it with a recording I took on mine some time ago, however, if you could upload the whole (CSV) file so all the parameters can be looked at that would really help diagnose this. All I can say is that mine has no throttle delay from hot or cold start...

Can you record the "inputs fueling" from start and on a short drive and then upload them here?

If you are not already overloaded with "how tos", there is a good write up here http://www.discovery2.co.uk/waterpump.html

You are welcome! I thought the bolts may be with threadlock already applied, but looking at pictures at various suppliers seem to show an ordinary flanged head bolt so I can't imagine what they are! I hope you get it sorted.

Could it be number 2 in? https://parts.jaguarlandroverclassic.com/parts/index/part/id/L5.L5G.L5G01.L5G01155/brand/land-rover/
