  1. The ECM and ignition coil are on whenever the ignition switch is in the "ON" or "START" position. Therefore, the system will generate a spark whenever the ignition switch is turned "OFF".
  2. Since spark may occur if distributor is moved with ignition switch in the "ON" position, keep switch off during underhood operations.
  3. Silicone dielectric compound must be applied to all insulating areas of distributor, coil, and spark plug boots. To help prevent radio frequency interference, coat distributor rotor tip with dielectric compound to a thickness of 1/32".
NOTE: DO NOT  use silicone dielectric compound on multi-point rotor.
