P0627 on Ford
Fuel Pump "A" Control Circuit/Open
P0627 on Ford vehicles indicates fuel pump "a" control circuit/open. Au7o has documented this code across 1 Ford model — most commonly on Fiesta. This code means the engine computer detected an open (broken) circuit in the control wiring it uses to command the primary fuel pump, so it cannot reliably switch the pump on. The fuel pump delivers pressurized fuel to the engine, so a control-circuit problem can cause low fuel pressure, hard starting, stalling, no-start, or loss of power. Because it can leave the vehicle stranded, it should be diagnosed promptly.
Common Causes of P0627
- •Faulty fuel pump relay or fuel pump driver module
- •Open, damaged, or corroded wiring in the pump control circuit
- •Bad electrical connector at the pump, relay, or PCM
- •Blown fuse in the fuel pump circuit
- •Failed fuel pump (internal open)
- •Poor ground for the fuel pump circuit
- •PCM/ECM control driver fault (rare)

- In-Tank Fuel Pump Failure — Stall Without Warning (Recall 15V005000)2014-2015
Improper nickel plating of internal components in the Bosch in-tank fuel pump can cause the pump to fail, letting the engine stall without warning and increasing crash risk. Ford issued NHTSA recall 15V005000 covering certain 2014-2015 Fiesta (and related Fusion/MKZ) vehicles built spring 2014; the recall was first announced January 2015 and later expanded April 30, 2015. Owners report intermittent no-start and stalling. Outside the recall window, general in-tank pump wear produces similar hot-restart/low-pressure symptoms.
