ISSUE:

 

Some 2011-2013 Mustangs vehicles may exhibit an intermittent drivability condition, crank/no start, a blown fuse 13 in the battery junction box and may have Diagnostic Trouble Code (DTC) P0627 stored in the Powertrain Control Module (PCM).

ACTION:

 

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

 

 

1. Remove the rear seat cushion. Refer to Workshop Manual (WSM), Section 501-10.
   
2. Inspect the fuel pump module wire harness for a chafing. Is chafing found? (Figure 1)

   3. Yes - repair the wiring harness. Refer to the Wiring Diagram (WD), Section 5.
       
      

[*]Route the harness so that it will lie in the recess area of the rear seat when the seat cushion is installed. (Figure 2)

The issue is that the rear seat cushion is sitting right down on top of the wire harness to the fuel pump in some cars and the harness gets worn out. The harness needs to be replaced and the new one is routed in the recessed spot in front of the cushion. The TSB pdf has nice photos. I will see if Robert land can fix the PDF up load.

This photo show where the rear seat smashes the wire harness.

 

 

This photos shows where to rout the new harness so it does not get smashed.

This one is for all Mustangs 2011 - 2013 and 500's from what I can see.
