SUBJECT: QUAD-4 ENGINE HARNESS (ALTERNATOR/ FUEL INJECTOR BRANCH) ROUTING REVISION


MODELS AFFECTED: 1988 SKYLARKS WITH THE 2.3L QUAD-4 ENGINE (VIN CODE D)

- An ECM Failure
- Rough Running Engine
- An Inoperative Fuel Pump
- An Inoperative Alternator
- An Inoperative A/C Compressor

FIGURE 1:

Any of these conditions may be caused by a shorted engine wiring harness (alternator/fuel injecter branch) which has rubbed against the alternator and/or is contacting the cooling fins on the alternator pulley (See Figure 1).

To address any of these conditions, repair the harness and install a conduit Tee, Part Number 12020308, to hold the injecter leads on the inboard side as shown in Figure 2.
Cars built after VIN JM023210 had the conduit tee installed on the production line.
