2005-2006 E-Series, F-Super Duty
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).
Use the following Service Procedure to identify a fault in the high or low pressure system.
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.
- 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.
- 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.
- 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.
