Preliminary Diagnosis

Important:
^ The following tests are designed for engines and batteries at normal operating temperatures and assumes that there are no engine symptoms which would cause a no-start symptom. The Battery must be in a charged state before doing diagnosis. To use the tests under other conditions could result in misdiagnosis.
^ Perform the On-Board Diagnostic System Check described in Computers and Control Systems to be certain no trouble codes are stored in PCM memory which may lead to misdiagnosis, specifically Diagnostic Trouble Code (DTC) 46, indicating a problem in the PASS-Key II Fuel Enable circuit. Testing and Inspection
^ Always note condition of "SECURITY" Indicator if Engine will not crank. If the indicator stays "ON" or flashes continuously, refer to Antitheft and Alarm System for "Theft Deterrent System." Antitheft and Alarm Systems
