NUMBER: 92-T-99

CORP.REF.NO: 208103

DATE: June 1992

SECTION: 8A, 9D


SUBJECT:
INTERMITTENT NO CRANK
- REPLACE STARTER ENABLE RELAY


MODELS/YEARS:
1992 EIGHTY EIGHT
1991-92 NINETY EIGHT


An intermittent "no crank" condition may be caused by a malfunctioning starter enable relay. The security light comes on for two seconds (five seconds on Eighty-Eight models) and then goes out, when attempting to start the vehicle. The vehicle, however, does not always enable the starter.

EIGHTY EIGHT
On Eighty Eights built before VIN NH337131 (Flint), and N1806991 (Wentzville), replace the starter enable relay with Part Number 25609047 (refer to the service manual for starter enable relay location) and change the wiring as per the procedure. On Eighty-Eights built after (and including) VIN NH337131 (Flint), and N1806991 (Wentzville), diagnose "no crank" condition using the service manual diagnostic procedures together with the enclosed updated diagnostic information where applicable.

NINETY EIGHT
On all 1991-92 Ninety Eights built before VIN N4325328, replace the starter enable relay with Part Number 25609047 (refer to the appropriate service manual for starter enable relay location) and change the wiring as per the procedure. On 1992 Ninety-Eights built after (and including) VIN N4325328, diagnose "no crank" condition using the service manual diagnostic procedures together with the enclosed updated diagnostic information where applicable.





WIRING PROCEDURE:
1. Cut circuit 439 (pnk/blk) wire far enough from the relay connector to allow for splicing. Strip the relay side of the wire for splicing. Tape back the harness side of circuit 439. Refer to Figure 1 for the wiring modification schematic.
2. Cut circuit 5 (yellow wire) far enough from there lay connector to allow for splicing.
3. Splice the three wires (both circuit 5 wires and the circuit 439 wire to the relay) together with a splice clip, part number 1839906, which can be found in terminal repair kit tool J38125-A. Follow the procedure for "splicing copper wire using splice clips" in the service manual, section 8A.

Parts are currently available from GMSPO.
