Subject:
INTERMITTENT NO CRANK (REPLACE
STARTER ENABLE RELAY)

Models
Affected:
1990-92 BONNEVILLE MODELS


CONDITION:

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

SERVICE PROCEDURE:

On vehicles built before VIN N1231988, replace the starter enable relay with Part Number 25609047 (refer to service manual for starter enable relay location) and change the wiring as per the procedure. On vehicles built after (and including) VIN N1231988, diagnose "no crank" condition using the service manual diagnostic procedures together with the enclosed updated diagnostic information where applicable.

WIRING PROCEDURE:





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 wiring modification schematic.

Cut circuit 5 (yellow wire) far enough from the relay 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.


Parts are currently available from GMSPO.
