Removal Procedure

WARNING: This page is about a different car, the 2004 GMC Sierra and 2004 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: There are two procedures available to install the distributor.

Use Installation Procedure 1 when the crankshaft has NOT been rotated from the original position.

Use Installation Procedure 2 when any of the following components are removed:

  • The intake manifold
  • The cylinder head
  • The camshaft
  • The timing chain or sprockets
  • The complete engine

If the malfunction indicator lamp (MIL) turns on and DTC P1345 sets after installing the distributor, this indicates an incorrectly installed distributor.

Engine damage or distributor damage may occur. Use Procedure 2 in order to install the distributor.

  1. Remove the air cleaner outlet resonator. Refer to Air Cleaner Outlet Resonator Replacement .
  2. Disconnect the following electrical connectors:
    • Camshaft position (CMP) sensor (2)
    • Fuel pump/oil pressure sensor (3)

  11. As the distributor is being removed, watch the rotor move in a counterclockwise direction about 42 degrees.
  12. Note the position of the rotor segment.
  13. Place a second mark on the base of the distributor (2).

    This will aid in achieving proper rotor alignment during distributor installation.
