# HARD STARTING, FALSE STARTING OR NO START

#### MODELS/YEARS 1989 CUTLASS SUPREME WITH 2.8L/3.1 L AND 1989 CUTLASS CIERA WITH 2.8L

Customers may comment of a hard starting, false starting, or a no start condition with vehicles having the above engine and model year combinations. This condition may also be described as a stall after start. Vehicles that display these conditions may have a Idle Air Control (IAC) valve pintle that moves when the engine is off.

If the subject condition is described by the customer, then complete the following:

1. Perform diagnostics, per Section 6E of the Service Manual. Replace any defective parts.

2. Make certain that all other bulletins for starting conditions have been considered and that the latest MEMCAL is installed in the vehicle. (89-T-49, 89-T-1 21)

3. If no problems were found using normal diagnostics, the latest MEMCAL is installed in the vehicle, and the condition still persists, then replace the Idle Air Control (IAC) valve with a new P/N 17112351.

Parts are currently available through GMSPO.

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.
