Publication Date: February 13, 2006

FORD:
2005 Excursion
2005-2006 E-Series, F-Super Duty

ISSUE:

Some 2005-2006 F-Super Duty/E-series and 2005 Excursion vehicles equipped with a 6.0L diesel engine may exhibit a hard start/long crank or no start condition due to low injection control pressure (ICP).

ACTION:

Use the following Service Procedure to identify a fault in the high or low pressure system.

SERVICE PROCEDURE

A minimum of 3.5 MPa (500 psi or .8 volts) ICP is required before the injectors are enabled. No or low oil in the system, leakage at the injector upper D-rings, high pressure pump quick connect fitting, high pressure pump discharge tube, faulty injection pressure regulator (IPR), or high pressure pump could cause low ICP pressure.

  1. Perform the revised Powertrain Controls/Emissions Diagnosis (PC/ED) lead diagnostics Section 4, Hard Start/No Start Diagnostic Procedure Tests 10E and 10F. These tests were revised in January 2006.
  2. If the leak is isolated to the high pressure pump quick connect fitting, it is recommended the male (5C3Z-9C854-A) and female (W301727) parts of the quick connect fitting be replaced together.
  3. Torque the female quick connect fitting to 38 ft-lb (51 N-m) max.

    NOTE:DO NOT OVER TORQUE THE FEMALE QUICK CONNECT FITTING OR DAMAGE WILL OCCUR.
