Hi, I am busy fitting a Digifant 2 wiring loom and ECU in a mk1 golf cabby I have fitted a 1.8 8v engine in, everything is connected but I have a couple of connectors spare, I know some of these are for lambda etc and aren't used, fuel pump is priming up, ECU is live when I connect the black/yellow wire to +12v, I know I need to connect this through an ignition relay, I've got fuel at the rail, I've got a good spark, engine is cranking over fine but the injectors are not opening, I have a feed at the injectors but no -ve pulse, here are a list of connectors I have left incase I have missed something:
green/white and black
brown/white and brown/green
red/blue/ and brown/white
black/yellow and brown
red/white and brown
I have black/yellow temporarily connected to +12v from battery
red/green connected to crank feed on starter motor
everything else that has a place to fit is plugged in, I appreciate any help, need to get this thing running it has stood for 3 months now, Thanks Tom :smiley:

I think to be able to diagnose anything a clearer description than given would be needed.
Where is the engine from? Where is the loom from? How is the loom fitted into the car? Straight into the fusebox?
What fuel pump are you using, what pressure do you have at the fuel rail?
