[QUOTE="FordTechOne, post: 1945274, member: 35543"] DTC P05A1 can be ignored, that’s an Active Grille Shutter DTC. With DTC P025A and U0109 along with datalogging showing a loss of fuel pressure, you’ll want to start there. Since you already replaced the FPDM, that leaves circuits, connectors, and pin fitment as the possible root causes. You can start by inspecting inline connector C1591 for dirt, corrosion, and loose/pushed out pins; it’s a black 34 pin connector located in the left rear side of the engine compartment. If there are no concerns there, then the next step is using a multimeter and extended length leads to measure the FPDM circuits front to back as well as verify power and ground to the FPDM. [/QUOTE]
