VEHICLES AFFECTED: 1992 "C, H" MODELS WITH 3800 ENGINE (VIN L, 1/RPO L27,L67)

This bulletin replaces Chart A-5, "Fuel System Electrical Test" in Section 6E3 "Driveability and Emissions" for 992 "C" and "H" carlines equipped with 3800 (VIN L and 1) engines. The Chart has been revised to check the correct ground terminal at the fuel pump relay, correct terminals at the fuel pump connector, and adds a check for he fuel pump oil pressure switch. Also, the chart A-5 facing page Circuit Diagram is incorrect. CKT 120 at the fuel pump electrical connector should be at Terminal "C" instead of Terminal "B" as shown. Please make the appropriate change to the following pages:

o VIN 1 - Page 6E3-A-32

o VIN L - Page 6E3-A-38

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.
