Injection Timing


  1. All timing and fuel adjustments are made by the Engine Control Module. If this appears after installation of a new or rebuilt injection pump, the keyway has probably been installed backwards.
  3. Refer to the illustration of timing marks. Be sure the keyway has been installed with the arrow pointing to the rear of the pump.
