Fuel Injection Pump Timing Adjustments: Notes
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, 2002 Chevrolet RV Cutaway, and 2002 Chevrolet Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
This procedure should be used after an injection pump installation or when the injection timing needs to be checked or adjusted. A scan tool must be used to check or adjust injection timing. A static timing mark can be used as a reference. If a static timing mark is not present on the injection pump mounting flange, one can be scribed to further assist in determining how far the injection pump needs to be rotated.
NOTE:
There will be no change in engine performance or vehicle driveability if the injection timing is advanced during the Time Set procedure. The injection timing must be set to the Injection Timing Specifications. If the injection timing is not set correctly, a possible DTC P0216 may set. See DTC P0216: INJECTION TIMING CONTROL SYSTEM
under SELF DIAGNOSTICS in ENGINE PERFORMANCE article.
NOTE:
Required Tools: Injection Pump Wrench (J-41711) and Injection Pump Adjustment Tool (J-29872-A).
