Answered your own question.

Check wiring. It will tell you if afm needs to be earthed.

Yes vacuum lines need to be connected. How else can the ECU know how much air is going in.

Have you got a high pressure efi pump connected? Fuels lines connected? Power from Sierra loom to the GTI loom?

[zooktastic]

yeah it has pumps, have you still not connected the vacuum lines yet ben?

[Bennyzarb]

Have connected them and found out what the one on the side goes to

[jimbo_jones]

have the car running sweet after a couple of adjustments one being that since i put my dizzy on the angle with a gear it made the rotor button spin clockwise instead of anti clockwise like the standard gti dizzy's do meaning everytime i reved it the computer was trying to advance the timing the wrong way. so i had tp press the crank angle sensor pickup gear of the dizzy shaft and flip it over making it work the right way.
after that the car is running sweet now so spent all last night cleaning up the wirring and putting the computer under the dash.

check A12 has a negetive feed from noise supresor or coil. thats your run signal

[jonno_racing]

yes i have fuel pressure BUT i dont have an exhaust on it or even an exhaust manifold but even though
i would still think it would run but just run rough like when i spray start ya bastard in the air box so to speak.
