Cheryl is right on here. If you can ground the light blue/orange wire and get the pumps to run, but don't get any fuel with the circuit hooked up normally, then I'd pursue that light blue/orange wire right to the PCM.
If the PCM isn't supplying a ground, then I'd suggest checking all powers and grounds before replacement.

Agreed! I sometimes end up taking pictures with my phone, since occasionally I'll want the wiring diagram AND a connector pin out. Mitchell won't let you use both at the same time, so I just photograph both and take it with me to the car.
