I relation to the dizzy, swapped out the whole unit for a known working one from the shell with the black and white stickered ECU shell so that’s a definite on the good side. But the info I got the sticker colours from was that thread about ecu pinouts

This one to be exact. So really I’m just grasping at straws here 
But I have ripped out the nerves to the engine on both shells and discovered some mad dodgy wiring from whichever previous owners handywork, so I’m in the process of patching things up and documenting changes, sorry for no pictures life is grasping me waaayy too tightly right now
