NOTE: Possible causes are: defective ignition system, defective air/fuel ratio control system, defective fuel supply system, defective EGR system, low compression or defective turbocharger system.
  1. Using scan tool, check for stored Diagnostic Trouble Codes (DTCs). If stored DTCs exist, perform appropriate test procedures for each DTC, and clear DTCs from ECM. If no DTCs exist, go to next step.
  2. Using stethoscope, check for operating sound at injector while cranking engine. If injector operating sound is heard, go to next step. If injector operating sound is not heard, check injector circuit. Perform DTC TEST NO. 12
  3. Check ignition timing. See procedures in the ADJUSTMENTS - 2.0L & 2.4L article. If ignition timing is within specification, go to next step. If ignition timing is not correct, check for correct installation of crankshaft position sensor and timing belt cover.
  4. Perform INSPECTION PROCEDURE 38. Once inspection procedure No. 38 is performed and all components are okay, go to next step.
  5. Check fuel pressure. See procedures in the BASIC TESTING - 2.0L & 2.4L article. If fuel pressure is not within specification, repair fuel system. If fuel pressure is within specification, go to next step.
  6. Check for defective ignition coil, spark plugs and spark plug wires. Check for defective EGR system, low compression and restricted fuel filter.
  7. Check turbocharger pressure and intake charge pressure control system. See the SYSTEM/COMPONENT TESTS - 2.0L & 2.4L article.
