fuel problems in 86.5

i bought my supra in a non running state. i have rerbuilt the motor and fixed all visible problems but my engine runs super rich. there is no trouble code from the car. ive replaced injectors,tps,fuel pressure regulator, fuel pulsation damper, and coolant temperature sensor. the air flow meter, cold start injector time switch,and the idle speed control valve are all reading normal when i put the ohmmeter to them. its so bad that when i floor it in neutral the fuel cut kicks in at 3000 rpm. if i disconnect the tps it idles at 4000 but then i do have throttle response up to redline without the fuel cutting off. if anyone can point me in another direction it would be great.
