So, I have finally given up on trying to run this with the electric injection system, although it was running fine this did not last and has proven beyond my skill and patience to continue with it and make it reliable.
This is really annoying because there is no obvious reason why, all the sensors and switches have been wired in. But I keep getting malfunction codes they keep changing, now the ecu has shut down and wont reset. It has beaten me so I hope it's happy now, living on the scrap heap.

On The Road
At last,on the road. I have used a mechanical injector pump taken from a TX1 Taxi, a really fiddly job replacing the pump. With hindsight I should have taken the inlet manifold off, would have made life easier. The pump it's self was easy to fit and time up, the engine started first go, once the air was out. I have keep the standard injectors and turbo setup, it runs sweet with no smoke, even when accelerating hard.
It's hard for me to tell what the driving difference is as I did not drive it much before the conversion and then only carefully as I was always worried it would blow up.Which it did.
It is certainty quieter with this engine even though its an older push rod design and drives very smoothly. Any way it can keep up with the other traffic OK so that's good enough for me. I am now checking the fuel consumption, so fingers crossed it's good because that will be the deciding factor whether or not I keep it.
So all that time and effort trying to get it running with the Maverick ECU was wasted, but to be honest I feel much better now it has the mechanical pump so much less to go wrong. The only thing not working properly is the engine malfunction light, I think I will keep it to remind me of all that work. The rev counter works fine I just wired the Maverick Flywheel sensor straight to the Navara sensor connector I kept the shielded wire in place just in case, in reality there are only 2 wires as the Mavericks 3rd wire connects back to one of the others via a shield wire. The temp sensors are the same and the Navara glow pug system works fine although a bit slower when cold.

Living with a Maverick Navara
Well I have been using the truck for a while now and enjoying it, the truck is returning 28 mpg average use which is less than I had hoped but better than I feared.
I loaded up with about 750kg today and seemed unaffected by the extra weight other than having a less bouncy ride. A real test will be towing a heavy trailer which is a job coming up soon. The truck is probably a bit slower and slightly less economical but this is outweighed by relief from the constant worry of it blowing up. It is also much quieter now especially on startup and when cold.
All in all if you did not know it had been converted you probably couldn't tell, all the electrics work the same and the engine bay is neat with only small clues to the change that only an experienced person would notice. As I have wired it into the ECU loom to power the injector pump the NATs is still effective at immobilizing the engine should anyone try without the key.

Last Update Jan 2016
I have been using the Navara for a few months now and all is going well, there is loads of low end grunt even when loaded, I hardly ever need to change gear on the open road. It will drive at 70mph easily and a bit more but it's not that happy and you can see the fuel gauge move. Most comfortable is speed is between 50 and 60mph when it is achieving nearly 30mpg. The original heater plug system works well, if a bit slower to heat up, still only a few seconds when its really cold. The only way you can really tell its been converted is the engine management light and the new cable throttle is a bit stiffer than most fly by wire cars nowadays.
Overall I am pleased, a lot of work to convert but the cost of the parts and tools I needed where covered by selling the parts I did not use or need. Good old ebay. A lot better than a new YD engine which would just blow up anyway. There are lots of things that can still go wrong but I am confident it won't be engine related.
Good luck if you are thinking of this conversion, just find a manual injector pump, it will be easier in the end. The London Taxi pump works just fine if you cannot find the correct one.

May 2016 update
The Navara is still going strong, in fact the more weight the better she goes.
Just passed the first MOT since the conversion and is being used daily. She has covered several thousand miles now and the fuel consumption seems to have improved, may be longer journeys responsible for that. Journeys we are happy to make now we a confident it will not blow up again, I must say it makes driving the tuck a pleasure without that worry every time you hear a slight knock or misfire.
