Help With 20v Afm / Car Wiring

I'm having a problem geting my car running. I recently put a 20V ST into an AE92. The "electrician" came and hooked up what was left of the wiring harness, but i believe he didnt do a good job. The car does not idle when the AFM is connected, unless i hold open the flap inside a good bit.

The car will only idle if the AFM is disconected but it burns very rich and gives poor power. I've been told that if the AFM is disconected the car shouldnt even start, thats why i think its a wiring problem. Im runing the f/pump through an ignition source wire, because he does not seem sure about what wire is for the f/pump. First he says its a black/red, then he said blue, and i've read, also have SEEN it on the diagram on club4ag, that its a green/red wire.

I tried conecting the pump to the green/red wire from the relay, and when i do so, the relay closes the circuit. I believe that shouldnt happen, unless the AFM is sending a signal to the relay, to close the circuit, making the f/pump turn on.

Any good Tech help will be great,

BTW, does anyone know how accurate the wiring diagram and color sequence for the ST 20V is on club4ag?
