2004-2007 Mazda RX-8 Engine Cranks No Start Service Bulletin

Some vehicles (mazda rx-8) 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 mis-application 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.
NOTE: • After repairs, provide customers with CUSTOMER INFORMATION on the last page of this bulletin
(for customers to try after a “CRANKS, NO START” condition, before towing to dealership).
