Intermittent No Crank, No Start, Starter Solenoid Clicks Engine Does Not Crank (Reprogram PCM)

Some customers may comment on a intermittent no crank when the key is cycled to start.

The customer may describe this concern as a single click noise when they turn the key as if the engine is trying to start. The ignition key can be cycled to off and then cycled to start and the vehicle will start. There may not be any DTC's set during this condition.

During the cranking process, electrical noise in the system is enough to sometimes signal the PCM that the engine is running and the starter relay is disengaged. When the key is cycled off it will reset the PCM that the engine is not running and will allow the vehicle to crank.

Important: Before reprogramming the PCM, verify the customer concern. Follow published diagnostics in SI. If no trouble is found, reprogram the PCM.

A revised engine calibration has been developed to address this issue. Reprogram the PCM with an updated software calibration. This new service calibration is available on TIS2WEB using the Service Programming System (SPS). As always, make sure your Tech 2® is updated with the latest software version.
