Thanks very much for the help sadly I ve done most of that already.

I ve checked ecu pins 20 and 19 no voltage. Checked ecu grounds and all OK.

I have 12v permanent on injection relay but no switched 12v. And 12v permanent on fuel pump relay but again no switched 12v. I have also checked continuity from the injection relay to ecu and it is fine.

I followed the réd and Black switched 12v from the injection relay under the passenger side dash and it arrives at the multiplug 6 pin next to the battery. From there it goes across the bulckhead above the engine and down under the fuse bon back into the car. I have checked continuity every 20cm along and from the fuel relay to above the brake pedal it is fine no brakes in the wire.

What I can t détermine is where this wire goes and where it gets it's 12v after ignition from.

Does anyone know if the 4 wires behind the ignition switch all turn to 12v when key is turned into the 2nd position ???
At the moment I have a red 12v permanent then when I turn the key to 2nd position I have a yellow and Black 12v, a yellow 12v but the last wire (blue and Black) stays négative. I assume the blue Black is for the starter motor.

sorry for the long post !
