Ignition System: Testing and Inspection
Electronic Ignition System Diagnosis
If the engine cranks but will not run or immediately stalls, the Engine Cranks But Will Not Start chart must be used to determine if the failure is in the ignition system or the fuel system. If DTC P0300, P0341, P0342, or P0336 is set, the appropriate diagnostic trouble code chart must be used for diagnosis.
P Code Charts
If a misfire is being experienced with no DTC set, for diagnosis, refer to Diagnosis by Symptom.
