Sooo.... final update!
It was the fuel pump!! Boot floor cut out and the cross members out, new pump in
big old hmmmmm as she primed and purged and the old girl is living again!!
Thanks for everyones help
EGR didnt change much - removed cleaned and back on making sure it was shut left without the vac lines - def felt stronger in 1st and 2nd, top end of 2nd under load and into 3rd same issue!!
I think think has to be fuel related now - no fuel in...
Sooo....
ECU came back from testing - was faulty so has been fixed, plugged it in when it came back and there isnt really any improvement
Anything im missing, im almost certain there is nothing in the main loom due to nothing coming out the end...
