EXTENDED CRANK TIME (NEW PART)

MODELS AFFECTED: SOME 1989 AND EARLY BUILT 1990 BUICK LESABRES, ELECTRAS, RIVIERAS AND REATTAS EQUIPPED WITH THE 3800 ENGINE (VIN CODE C)

Some 1989 through early built 1990 LeSabres, Electras, Rivieras and Reattas equipped with the 3800 engine (VIN Code C), may exhibit a condition of a cold engine extended crank, but if the ignition key is cycled, the engine will start.

If this condition is experienced on a vehicle with good fuel pressure and the basic engine controls and systems are performing properly, it may be necessary to install a new service Mem-Cal with a recalibrated fuel multiplier ratio during cranking.

Service Mem-Cals are currently available from GMSPO.

IMPORTANT: The new calibration Mem-Cals are currently being used in production. Verify if this Mem-Cal is already installed by the Scanner I.D.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
