Some 1987 Regals equipped with a 5.OL engine may experience a no start, quit, or poor driveability condition which may be caused by a poor ECM ground on the engine. Tightening the ECM grounds on the rear of the engine may correct the condition. All other diagnostic checks should also be performed to ensure the condition is corrected.
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.
