Checking Secondary Ignition & Timing

NOTE: After each repair, perform TEST VER-2  .
  1. Turn engine off. Connect engine analyzer to engine. Start engine, and let it idle. Set scope to read display or parade pattern. Follow equipment manufacturer's procedure for pattern analysis. If secondary ignition pattern is not okay, repair indicated component in secondary ignition system. If secondary ignition pattern is okay, go to next step.
  2. Remove all lower spark plug wires one at a time from ignition coil. Observe secondary kilovolt line. If open circuit secondary voltage is not at least 25 kV, replace electronic ignition coil. If open circuit secondary voltage is at least 25 kV, reinstall spark plug wires. Go to next step.
  3. Ensure engine temperature is more than 180°F (82°C) before proceeding. Using scan tool, read spark advance. Increase engine speed to 2000 RPM. If spark advance does not change with increase in RPM, replace Powertrain Control Module (PCM). PCM is located under air cleaner. If spark advance changes with increase in RPM, test is complete.
