In that case the Dk Green/White wire has to be disconnected from the relay box (PDC) or broken somewhere between the PDC and the pump. Fuel pump relay cavities should be connected as shown below:
Cavity 16 - to fused power (B+) Dk Green/Black wire
Cavity 17 - output to fuel pump Dk Green/White wire
Cavity 18 - fused ignition (hot in START and RUN) Orange wire
Cavity 19 - empty
Cavity 20 - relay control from onboard computer (PCM) Dk Blue wire
Battery voltage is always present at 16. When ignition is turned to START or RUN, voltage goes to 18. PCM grounds 20 and relay is energized (clicks), sending voltage to 17 and on to the fuel pump.
Start your search by removing the PDC and inspecting the wiring connected to it from the bottom. Isolate the Dk Green/White wire and make sure it is in fact connected to the PDC. If it is, then you could either trace and find where it is broken, or cut it right there and run a new wire to the fuel pump.
Please let me know if you any other questions.
