ISSUE
Some vehicles may experience a hard start/long crank time condition. This may be caused by the Powertrain Control Module (PCM) calibration, Idle Air Control (IAC) valve, or the fuel pump depending on the vehicle symptoms. This TSB has been developed to aid the technician in diagnosis.








ACTION
Perform normal diagnostic procedure as outlined in the Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual. If concern is not found, refer to the following text and Figures 1 and 2 for additional diagnostic procedures.

Crank time is measured from voltage drop to 700 rpms. Crank time should be approximately 1 second for ambient temperatures at or above 000 (320 F) and should not exceed 6 seconds at or below -29°C (-20°F).





Obtain an Authorized Modifications Decal (FPS 8262 - obtainable through DOES II, 25/pkg) and list the date, dealer number, and summary of modifications performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
