Welcome, I am Chris.

Check fuse 37 under the hood. Check for battery voltage B+ on the White wires of both the Fuel Pressure Control and the Fuel Volume Control valves. If there is no voltage, check for voltage on the White wire, both sides of pin 10 at connector C 1047 its 16 pin connector that is black next to the passenger wheel well. This will tell us if we need to trace a wire broken.

If there is voltage at the valves, trace the Grey/Brown from the Fuel Pressure Control valve and the Blue/Orange from the Fuel Volume Control valve to the PCM and see if there are issues.
