Ignition System: Testing and Inspection

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 the ignition system or the fuel system. If DTC P0300 through P306, P0341, or P0336 is set, the appropriate diagnostic trouble code chart must be used for diagnosis.

If a misfire is being experienced with no DTC set, see Diagnosis By Symptom. Testing and Inspection
