Publication Date: June 2, 2005

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

This article supersedes TSB 04-25-18 to add a vehicle line and update the vehicle build date information.

ISSUE:

Some 2005 F-Super Duty and E-Series vehicles built prior to 4/15/2005 and Excursions built 1/10/2005 through 4/15/2005, all vehicles equipped with 6.0L engine, may exhibit a crank no start with low injection control pressure (ICP), hard start/long crank with slow to build ICP, or a rough idle with high ICP.

ACTION:

This condition may be due to the injection pressure regulator (IPR) and the high pressure oil pump (HPP). Refer to the following Service Procedure.

SERVICE PROCEDURE

  1. Remove the IPR valve and inspect for deformation of the screen (screen sucked into valve), a hole in the IPR screen, or metal debris covering over half of the IPR screen.
    1. If any of these conditions are present, change the engine oil and oil filter, then replace the HPP and IPR valve. Refer to Workshop Manual Section 303-04C to replace the HPP or the IPR.
    2. If none of these conditions are present, continue with normal diagnostics.
  2. Start and run engine to confirm repair.
  3. If rough idle is still present, debris may have contaminated a fuel injector(s). Run normal injector diagnostics to identify specific injector(s) before replacement.
