### Condition

Some customers may comment on a crank and no start condition. This may be experienced on vehicles that have repeatedly been driven short distances without reaching operating temperature. This condition is most likely to occur when the vehicle is still a dealer stock unit or when the vehicle arrives at the dealership on the transporter. This condition may also occur if the car is driven in short duration trips.

DTCs P0335 and/or P0341 could be stored in history if the engine was cranked excessively with fouled spark plugs. DTCs P0300 - P0304 may be stored if the engine eventually starts with the fouled spark plugs.

### Cause

This condition may be caused by the engine not reaching operating temperature before turning off the ignition.

### Correction

Refer to Spark Plug Replacement in SI for replacement of the spark plugs with P/N12617309. The replacement higher heat range spark plugs have better cold start characteristics.

Clear any DTCs stored in the PCM. In order to prevent a reoccurrence, allow the engine reach operating temperature before turning off the engine and returning the vehicle to the customer.
