SERVICE MANUAL UPDATE DRIVEABILITY & EMISSIONS CHART

Models Affected: 1989 GRAND AM

The A-3 Diagnostic Chart (Page 1 of 3) is revised to identify the correct beginning step to follow after No RPM or 2X Signal is received.

This Chart replaces the present Chart A-3 (Page 1 of 3) "Engine Cranks But Won't Run" found in Section 6E "Driveability and Emissions" in all 1989 Grand Am Service Manuals with 2.3L (VIN A and D) LD2/LGO engine applications.

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.
