I stuffed a 1994 3.2 with stock harness into a 1926 Model T touring car. She has fire and turns over but no fuel. Fuel pressure is about 40 and returning to the tank. Both leads going to the injectors are POSITIVE!!! I did not change any harness on the motor but adapted the engine compartment harness to fit the size and position in the smaller car. In doing so I eliminated the following pins: PCM: 2 brake on/off, 5 turbine shaft, 10 air clutch, 11 purge solenoid, 14 trans control lamp, 26 VREF voltaage, 27 EGR feedback, 28 power steering switch, 33 EGR solenoid, 38 trans pressure control, 41 trans control switch, 42 air clutch, 49 trans temp, 51 shift solenoid, 52 shift solenoid, 53 converter clutch, 54 WOT cut out, 55 shift solenoid. From the CCRM I eliminated pins 16 AC clutch, 21 AC relay and 23 AC clutch. As I understand it, the red power lead to the injectors is constant positive. The individual color coded wires going to individual injectors carries negative power from the PCM firing the injector. If I unplug the PCM factory plug from the injector harness there is no power (+ or -) coming from the PCM pins to the plug. The engine plug from the injector harness reads positive when is should be negative. I could understand one or two injector wires being shorted but all six injectors read positive. No fuel no fun. Any ideas or how to test??
Thanks much in advance,
