S-AFC 2 Problems

[Spider228]

I got a 93 dx and i just tryed to put in an afc to controll my injectors for my turbo setup. When i hook up the yellow and white wire the car wont start. I did the intial setup and tripple checked everything. The car wont start. I am for sure everything is hooked up properly.

Red= Power
Green=Rpm
Gray=Throttle
Brown=Ground (Ecu side)
Black=Ground (1cm Apart)
Yellow=Pressure signal output (Ecu side)
White=Pressure signal input

This is what i used to install it.

i see that all your wire is correct.

so try to remove all the wire and start the engine . if it start ok then rewire the safc 2 again then start the engine if not it will be some thing from three things 1- the safc2 itself have a problem
2- the wires is bad
3- wrong wire

it will start and run fine with the white and yellow not hooked up, but when i hook them up it wont start. The rpms read fine the throttle percentage is good and the throttle voltage is good. Its the yellow and white wire that is giving me a problem.

what did you do the injector percent at 1000 rpm at the low throttel it suppose to be -40% did you do that ?

yep and it still wouldnt start

i think you have to try other safc2 from any friend . but be sure it work good. then try only the other safc2 unite at your wires . then if the engine start that mean your unite has a problem . if not start that mean your wires has a problems.
