WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
P0627 - FUEL PUMP A CONTROL CIRCUIT/OPEN

Description:  The powertrain control module (PCM) monitors the fuel pump command (FPC) circuit output from the PCM. The test fails if the FPC output is commanded OFF and the FPC circuit voltage is lower than an expected threshold, when the PCM expects to detect B+ voltage coming through the fuel pump relay coil to the FPC circuit.
Possible Causes: 
  • Open B+ circuit to the fuel pump relay
  • Damaged fuel pump relay
  • FPC circuit open in the harness
Diagnostic Aids: 
Application  Key On Engine Off  Key On Engine Running  Continuous Memory
