3tgte starts, but floods

well i got 3tgte to run - five plugs were screwed!!
but its very very rich and black smokey.
what could be causing this?
i tried to run the hp fuel pump directly from the battery ie 12v constant but the engine dies. should this happen? shouldn't the regulator and injectors control the amount of fuel regardless?
i can hear a clicking from the fuel pressur relay prior to it cutting. i assume what is happening is it is getting a signal from the afm that more air is coming in, then actuating the fuel pump which in turn floods the engine.
the injectors could be opening too long too i suppose.
i must have gone through about 8 litres of gas in twenty minutes max. that would mean they were flowing around 100cc/ min on idle, which is way too much i would have thought
any thoughts?

Straight out grab a multimeter, and put the car in the "On" position, and measure what volts/amps/Ohms you get from the AFM as you move the accel
Next, check to see what signal LENGTH (Oscillator screen) you are getting to the injector...
Or before that one, you could also pull out each injector, grab a 9v battery, and throw it across the injector, see if it moves heaps, or little...
If it moves little, get it properly cleaned, it's a) jammed open, b) jammed shut
Then with injectors out, compare them, are they open (when closed) at different lengths?
The other thing to check is what voltage is being recieved from the O2 sensor (Using multimeter)
Also, what computer are you running?

Something simple, but is the wiring to the coolant temp sensor okay (or is the plug on properly)? If this is open circuit, your ECU will run as if the motor is cold all the time, injecting substantially more fuel.

yes that is plugged in but i guess its possible the sensor is not working. is there somehow i can check if this is working or could i trick it by just shorting the connection and tricking it

I wouldn't have a clue on which ones to check (Pins on AFM)
If you got me a wiring diagram of the AFM and of the ECU I could tell you then...
And the AFM should change in Ohms from memory (thats why I said check all 3)
