Hi Dave. Hope all is well. I've been at this a long time and finally found the fix to high fuel pressure and all around bad engine performance. We were able to trace the problem to the 02 Sensor signal wire. This is the one concealed in a rubber capsule, and it connects to the ECU. Turns out the signal wire was shorted and had to be replaced. A new signal wire is now in place and the engine is running perfectly without any fault code.
Thanks again to you Dave and everyone else who extended a helping hand.

All is well. Now that I had surprise heart surgery in late Nov. 2015 (3 months ago).

Happy that you (finally) figured out you issue. So no code? DTC 00525? Blink 2343

You're talking about the single female spade connector (the two pin with the white wires is the O2 sensor heater):
