Head rebuilt and now for the body work inspection and respray, then retrim etc etc.....
It didnt even occur to me that it could be the ECU earth, i assumed fuel pump relay cause i'd been messing installing a hidden cut off switch to pump. But in my case it was obvious once i saw an earth sitting there when it should have been bolted to battery with the others.
Glad you're sorted!
