just rebuilt a ahu. motor was toast, bought it like that, rebuilt it, and now its running. I couldn't get it running. I cranked it over with no fire. I hooked up the vag com and the only thing I pulled up was the fuel shut off solenoid, open or short to ground(n109). I checked the 109 relay and it seems to work. the glow plugs seem to be hooked up to this relay and without it, they don't work. with it, the glow plug light comes on, and stays on. The fuel shut off solenoid however does not. I took a positive wire from the battery and grounded out the solenoid. it will fire up if I do this. I have read that the needle lift valve wiring may have something to do with this? I had the original #3 injector worked on and I got a different one back. mine was so bad that frank worked me into a different one with a different plug. I have it jerry rigged to work with my harness. I have a blue wire and a grey wire from the harness. on the plug, there is positive and negative labeled. I have negative hooked up to the grey, and positive up to the blue. does that sound right? I pulled the 109 relay out and I tested it. it works fine it seems. any help on this would be great. now the time for the breakin.
