Bulletin Summary
This Preliminary Information communication provides information to the technician about vehicles that have extended or long crank time during cold ambient air temperatures. Direct Injection systems run at higher pressures, and the mechanical pump on the engine must build up the required pressure before the first injection event occurs. Direct Injection engines may have slightly longer cold crank times than that of port fuel engines.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
