R34 Starting Issues

[mawzy]

Hi all, long time reader, first time poster. I've usually found all the answers to issues, but this one has me stumped, and have not seen any posts with the answers I need. I have an r34 gtt tiptronic, which i converted to manual, and had running fine. The motor later on had a mischeif, and got thrown in the bin, (long story short) now 8months later, i have aquired a manual neo motor, which I have put into the car. Now, my problem is i can't get the car to run. It starts, kicks up to idle then dies. I have had a scanner connected to the car, and it could not detect any faults. Airlow was fine, cas was fine tps was fine. Automatic was throwing a few codes, but seeing as it isn't there that was to be expected. the car still sparks as it turns off, And it sounds primo firing all 6, and the injectors are all firing. it seems as though the ecu is stopping the car for an unknown reason.

Now this is where I need help, There's one plug that I managed to completely strip when pulling the motor out, and now I can't find where it reconnects too. i know its something to do with the automatic, cos the manual loom bits that come with new motor don't have it. There's a clip with three plugs, midway along the intake manifold, between it and the driver side strut tower. red black and silver. (there's also the same colour combination at the front of manifold, for the tps and traction control) The plug I'm having issue with is the silver one. Can someone tell me where this connects too? What it does, and or take a foto of this? And the colour the wires are that connect to it? Also, could someone try start their 34 with this unplugged? To see if this is indeed the cause of my problems. I'm really hoping it is, because apart from this I'm at a dead end. Or if anyone can suggest other areas to look or test, I'd be really grateful. Thanks in advance to anyone who can help.

Have you got the fuel lines around the correct way and is there fuel in the tank?

[mawzy]

Yes to fuel lines and fuel. We even tried hard wiring fuel pump to battery, to rule out power supply issues to that. No such luck. But after a looking at a non turbo tiptronic yesterday, it didn't have the same plug configuration. Only a single black one, not the three. so limits me now to finding a tiptronic turbo to look at or if someone can post pictures, would be very grateful. thanks very much.
