Not good enough!  :tongue:

red/yellow - fuel pump trigger
red/green - starter motor live
yellow/black - ecu power (from ecu relay)

Might be worth checking with a mk2 person though.

my dad just said there is only one spark when its cranked so im guessing it could be one on all or one from the coil?

the red/yellow - has been wired to fuel pump trigger
red/green - has been wired to starter motor live
2x yell/black cables have been wired to power so now there is power to ecu
when the key is turned and held at crank position there is one cycle of sparks to each plug then nothing and also there is no power to ecu...?

Strange, probably something for the mk2 boys again.  :undecided:

Poorly coil maybe?

Has it got an imobiliser?

it did have an immobiliser but i took the ignition barrel rear housing off and ripped the immoboliser out and wired it back up as norm to the ignition.
