    Default 20v not starting

    almost finished installing 20v 4age into my ke70, but cant get the motor to start. The injectors aren't pulsing (checked with noid light). Im getting spark, but no fuel. The injectors are earthed ok, so i figure the problem is between the injectors and the computer. Anybody have any ideas where to check next?

    plus anyone know where i can get a rwd plenum for 20v ST?!

    injectors are actually earthed thru the switching outputs of the ECU.

    One pin of the injector gets 12V+ from your EFI Main circuit, and the other pin goes to the injector output on the ECU which switches to earth to fire the injectors.

    It's quite possible you've fuffed that part up
    ...... butt scratcher?!
