TEST NS-SELNO START SELECTION MENU
NOTE:The battery must be fully charged before performing any test in this manual.
NOTE:If the engine will not crank or cranks but will not run, be sure to check the Sentry Key
Immobilizer Module (SKIM) for proper communication and trouble codes.
NOTE:With the DRB, attempt to read ECM trouble codes. If the DRB is unable to communicate with
the ECM, perform test NS-2A. If there are any trouble codes present they must be repaired before
continuing with the No Start Symptom diagnostics.
Below you will find a recommended procedure to correct a No Start Problem by symptom. They
should be performed in the order that they are listed.
Repairing a No Crank Condition..............................................NS-1A
Repairing a No Response Condition...........................................NS-2A
Repairing a No Start Condition................................................NS-3A
Repairing a Start and Stall Condition...........................................NS-4A
Checking the Engine Mechanical Systems......................................NS-5A
NOTE:A failed engine coolant temperature (ECT) sensor can cause a cranks but will not run or an
extended cranking before starting condition. This occurs when the ECT sensor calibration fails
(sensor indicates engine temp is warmer than actual engine temp) and the ECM cannot command
proper fuel quantity to the injection pump.
NOTE:For all component locations seeGeneral Information Section 4.0 in this manual.
