Distributor Position & Reference Timing

  1. Check and adjust distributor position after disconnecting Pink wire and removing distributor cap from distributor. Crank engine until rotor points toward rear of engine and number one piston is at TDC. If necessary, use a socket on crankshaft bolt to turn crankshaft.
  2. White mark on rotor should be aligned with White pointer on distributor. If not, loosen distributor clamp bolt and turn distributor to align marks. After adjustment, tighten distributor clamp bolt.
  3. 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.
  4. 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 (22 degrees on California models).
  5. If ignition timing is incorrect, loosen distributor clamp bolt and rotate distributor until timing is correct. Tighten bolt and recheck timing. Remove jumper wire from reference timing connector. The "CHECK IGNITION" indicator light should go out.
