DETAIL
During previous winters Land Rover has received numerous reports of poor starting of 1994-1995 Defender 90 vehicles in extremely cold weather. This condition would arise when a vehicle has been cold soaked overnight in ambient temperatures below 20°F. There may be complaints of long crank time, slow crank speed, or a no-start condition. Upon inspection the engine will appear to be flooded (overfueled). Land Rover has developed the following procedure to correct this condition. All items must be completed in order to improve sub-zero starting performance.:
^ Oil and filter change
^ Starter replacement
^ Replace battery cables
^ Change PROM in ECM
^ Update coil primary connections
^ Battery, charging system, and ignition system inspection and testing
These procedures are an extension of the Land Rover OPERATION PRIDE concept developed for the Discovery and Range Rover Classic. Each component must be ordered individually but all the parts must be installed for the customer to benefit from the cola start package.
ACTION REQUIRED
Upon customer complaint for the symptoms outlined, perform the specified repairs.
