I don't think all the injectors would go out like that, maybe I didn't word it well but just saying mine ran ok with the disco map.
Did you check for faults after trying the new ECU wonder if you get the same faults.
Battery may be a bit low how long does it hold up before it goes too low started pull quite a few amps

it wont start though will crank well enough with that voltage drop,try jump leads as well or a very good battery
so connected jump leads to my other landy (300tdi) and cranked the motor. Turns quicker but still won't start. Its coughing and spluttering alot with white smoke. It's like the injectors are not getting enough fuel.
Ran the nanocom after all the cranking and I got an extra fault 'noisy crank signal has been detected'. Any ideas anyone?
I'm at a loss.

That's starting to sound promising. I was going to say that 8 - 10 v is a bit low to start a TD5 but James has beaten me to it. Noisy crank signal could be a crank position sensor on the way out or it could be the starter motor creating interference. With the new(ish) battery connected (put it in the footwell or something) is there anyone who could give you a tow start? If it will fire up with a bump start but not on the starter motor then you know what the problem is.
I could get the missus to tow me in the 110 but we live in a busy area so that might be tricky.
Right so some very good news. The td5 is all up and running, happy days. Turned out to be my new Crank sensor was faulty. I removed it and fitted it to my mates td5 and guess what, his engine wouldn't start.
Those short peak charges= broken ecu.
Why on earth didn't my nanocom pick up the crank sensor issue from day one? Maybe because my old ecu was broke, nanocom couldn't pick up the crank signal issue.
And I thought all along it was fuel issue and hacked out an access panel for a new fuel pump, new fpr, new seals and washers.
What a massive relief.
Thanks to everyone who helped and gave me good advice. Really appreciate it.
All the best

Good to hear you've made some progress. The trouble is with Land Rover electronic systems is that they don't have self awareness in the sense of AI, so there's a limited number of faults that can be detected and a limited library of error codes that can be displayed, and the don't cover everything. However, living with a TD5 with a Nanocom is still a lot easier than living with one without. I wouldn't dare drive a TD5 without a fault code reader of some sort.
