CAMPAIGN: COLD START VALVE- THERMAL AND TIME SWITCH WIRING

COLD START VALVE THERMAL AND TIME SWITCH WIRING HARNESS INTERCHANGED

MODELS/YEARS: 1986 CUTLASS CIERA MODELS EQUIPPED WITH A 2.8L MPFI (VIN CODE W) ENGINE

CONDITION

General Motors has determined that some 1986 Oldsmobile Cutlass Ciera models equipped with a 2.8L MPFI (VIN Code W) engine may have two circuit wires interchanged in the cold start valve thermal and time switch.

This can result in a grounding of the cold start injector power circuit. This grounding can blow the 10 amp fuse in the "crank" cavity. If this occurs, the cold start injector will not operate, causing a difficult or no start condition.

To correct this condition, the circuit wires are to be inspected and, if required, reversed and the "crank" fuse replaced per instructions in this bulletin.

VEHICLES INVOLVED

A total of 16 Oldsmobile Cutlass Ciera models equipped with a 2.8L MPFI (VIN Code W) engine are involved in this campaign. Vehicle identification numbers of involved vehicles are listed below:

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.
