From all this thread which i followed from the beginning at this point i'm not convinced at all that it's air in the system cos if it was the symptom should have not occured after a purge sequence IMO
Even if the injector copper washers haven't sealed? In that case, that's the next thing that's getting changed!

Again? 
...IMO in any case if the problem is air in the system after a purge the engine should start and run normally cos that's what the purge does, it eliminates the air if there is any

I left it running yesterday for about half an hour and took it for a short trip, no more noisy pump it seems. Also not so much splutter on startup.
Didn’t get around to doing the alternator today but we did take it for a spin.....
Also got some nanocom data of startup : https://www.dropbox.com/sh/h6k1vw2vevd461t/AAAi4FZi5XgKuq7SJRhZUf3Xa?dl=1

One thing I did notice from these results is the road speed is not recorded!

Was this log recorded at the beginning of the trip immediately after start up and does it cover the whole 30 minute driving? ... i think the defender ECU doesnt get the VSS signal for road speed cos the speedometer is driven by that transducer on the TB not by an ECU like on a D2
record a log when the engine is up to operating temperature cos i've seen some suspect readings there

This is just a short trip including startup, a few minutes at most, as I haven’t bothered MOT’ing it I’m a bit limited how far I can go. I had never noticed before that the road speed was missing from the log, I’m sure I can see it on live data and from memory I’m sure I can on Lynx too.
EDIT: Nanocom does not display the road speed, the speedo does though

then it's might be nanocom glitch
New alternator, getting 13.24v on Nanocom - is this is a bit low? I would have expected 14v+
Here's a very short run: https://www.dropbox.com/s/tlvmi5uo5uref4s/L90 21022018.CSV?dl=1

Multimeter on battery is showing 14.5ish when engine running, varies from 13.5 to 14.6 when driving
Ran some jump leads from the battery negative to chassis/earth and another jump lead from battery negative to ecu earth and readings are a lot better. Not sure if this will help with the starting issue or not....

love the vid apart from the turbo shut down part
add some LPG into the mix and it will blow your mind
Lol how many times have you changed your glow plugs and injector seals ?
What makes you think it’s overfuelling? Yes Dynachip done it a while back, we only roughly checked the boost it needs lengthening at bit again
It was missing a bit whilst out I was checking it wasn’t doing it all the, Nanocom showed up to 1.42 boost so it was over boosting a bit
The black smoke says it is.
L
It smokes less than it did before the remap, dynachip knows what he’s doing. It only smokes when I should have changed down a gear. If it did it all the time I would be concerned.

It should not smoke at any stage unchipped, chipped a little can be expected.
Really? I’ve never had any diesel new or old that didn’t smoke a little when laboured a bit.
What are you thinking is wrong with it?
