For 1990-2009 cars

Always start the diagnosis with the Powertrain On-Board Diagnostic (OBD) system check. This will reduce the diagnostic time and prevent unnecessary parts replacement. For additional information, refer to the following procedures:

• | Engine Cranks But Will Not Run in Engine Controls

• | Ignition System Diagnosis in Engine Controls

• | DTC P0300 -- Engine Misfire Detected (also DTCs P0301 through P0306 for misfire on a specific cylinder).
