Download Some vehicles may experience difficulty starting (cranks no start). This may occur after driving the vehicle a short distance without engine reaching normal operating temperature. Examples: starting a vehicle and moving it to wash it, engine stall due to misapplication of clutch then restart. This commonly occurs at port facilities or dealer lots where vehicles are frequently started cold, moved for short distances and then turned off. This concern may also occur due to low cranking RPM during engine starting. A cranks, no start condition may be caused by fuel flooding resulting in either fouled spark plugs or lower than normal compression. Carefully follow REPAIR PROCEDURE “A” and refer to VIN application to determine necessary repair action. The following vehicle mass production changes have been implemented to improve starting performance: • PCM calibration – The PCM calibration was modified to reduce fuel injection amount during cold conditions. PCM calibration was modified in vehicle production on 3/12/04. • Battery – A higher capacity battery was introduced (6/1/04). • Engine starter – Revised to increase cranking compression at engine start. Implemented into vehicle production 11/8/04 (For AT models), 12/1/04 (For MT models).
