Some comments on cold and warm engine starting procedures have resulted in a change from that printed in the owner's manual.
The new procedure contained in this bulletin should be reviewed with all Sales and Service Personnel and be provided to customers that may be encountering hard or no starts.
3.0L CARBURETOR ENGINE ---------------------- COLD ENGINE (-26 DEG C OR -15 DEG F AND ABOVE WITH OR WITHOUT BLOCK HEATER)
Push down the accelerator pedal to the floor and slowly release it. With your foot off the pedal, crank the engine by turning the ignition key to 'Start'. Release the key when the engine starts. If the engine does not start, or starts but fails to run, repeat this procedure.
DO NOT PUSH DOWN THE ACCELERATOR PEDAL. WITH YOUR FOOT OFF THE ACCELERATOR PEDAL, crank the engine by turning the ignition key to 'Start'. Release the key when the engine starts.
If you tried the warm engine starting procedure (or the cold engine starting procedure), and the engine still does not start, press the accelerator pedal to the floor and hold down firmly while cranking the engine. This will clear the engine if it is flooded.
Completely depress the accelerator pedal three times, hold the pedal halfway down, and begin cranking. Do not release the key until the engine is definitely running. At this time release the key and slowly release the gas pedal until the engine idles on its own. DO NOT PUMP THE ACCELERATOR PEDAL DURING CRANKING.
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.
