Base Ignition Timing Check

1. Turn the ignition key OFF.
2. Place the transmission in PARK (A/T) or NEUTRAL (M/T).
3. Turn OFF all electrical loads (A/C, heater, radio, lights, etc.).
4. Disconnect the SPOUT connector.
5. START the engine using the ignition switch. DO NOT use a remote starter for this step.
NOTE: If engine starts then stalls go to pinpoint test S2. If the engine will not start, proceed to IGNITION SYSTEMS.
6. Using an inductive timing light, check ignition timing.
NOTE: For a 2.3 Dual Plug engine use the exhaust side plug. If timing does not work, go to Key On Engine Running (KOER) self test. Key ON Engine Running (KOER) Self-Test
a. If the timing is within ±2 degrees of specifications, continue with Computed Timing Check. Computed Timing Check
b. If the timing is not within ±2 degrees of specifications, adjust ignition timing (Distributor Ignition (DI) systems) or refer to IGNITION SYSTEMS for possible causes of improper timing (Electronic Ignition (EI) systems).
