Publication Date: MAY 22, 1995

ISSUE:

Some vehicles may be hard to start after the fuel injectors have been replaced.  This may be due to air being trapped in the high pressure fuel lines.

ACTION:

Before installing fuel injectors, dip the fuel injectors in engine oil.  By dipping the injectors, the oil purges the air from the oil passages and reduces the possibility of air entering the injector.  Refer to the following Service Procedure for details.

SERVICE PROCEDURE

Dip the injectors in oil up to slightly higher than the upper groove.  Install the injectors as outlined in the 7.3L DI Turbo Diesel Service Manual Supplement, Pages 03-04E-17 and 03-04E-18.

NOTE:

BE SURE TO USE CLEAN, HIGH QUALITY ENGINE OIL THAT MEETS OR EXCEEDS OIL SPECIFICATIONS OF DI TURBO DIESEL APPLICATIONS.
