Distributor Position & Reference Timing

  1. Check and adjust distributor position after disconnecting Black-/Pink wire and removing distributor cap from distributor.
  2. Crank engine until rotor points toward rear of engine and number one piston is at Top Dead Center (TDC). If necessary, use a socket on crankshaft bolt to turn crankshaft to TDC.
  3. White mark on side of rotor should be aligned with White pointer in distributor. If not, loosen distributor clamp bolt and turn distributor to align marks. After adjustment, tighten distributor clamp bolt.
  4. With distributor position correctly adjusted, connect a jumper wire between ground and reference timing connector. See Figure. Connector is located below glove box, next to controller assembly.
  5. Turn ignition on. The "CHECK IGNITION" indicator light on instrument panel should come on. With transmission in Park, parking brake applied, and drive wheels blocked, start and run engine at idle. Ignition timing should be 20 degrees before top dead center.
  6. If ignition timing is incorrect, stop engine and loosen timing adjuster bolts. See Figure. Rotate timing adjuster bolt clockwise to advance timing or counterclockwise to retard timing.
  7. Tighten adjuster clamp bolts and recheck ignition timing. Remove jumper wire from reference timing connector. The "CHECK IGNITION" indicator light should go out.
