Its been along time, but the car finally starts and runs
The problems i was having were a combination of old loom, and a few intermittant faults. I had 3 pins on the ECU which worked when they felt like it, wires in the loom that had started to fray and breakdown with age, hence why occasionally i could get the readings.
I had to admit defeat in the end though and paid someone to come and sort the loom. As i havent alot of time away from work and i needed the car finished so got him to go over the loom, in the areas that i knew there was problems, replace all the loom plugs, renew all ECU pin outs and re-wrap the loom accordingly as he went, all for £160
Now its time to get the welder out for the rear turrets
I would just like to say though a massive thanks to Rich and Daz for ALL your help
