(Repair Engine Wiring Harness)
Models:
1998 Chevrolet Cavalier
1998 Pontiac Sunfire with 2.2L Engine (VIN 4 - RPO LN2)
Condition
Some customers of J cars with the LN2 2200 engine may experience a blown fuel pump fuse, no start, or driveability concerns.
Cause
Condition may due to two areas of engine wiring damage. The # 4 fuel injector/EGR harness may contact the RH front corner of the brake master
cylinder, resulting in damage to one or more of the wires in the harness bundle. Also, the main engine wire harness may contact the transaxle cooler line
bracket near the transaxle on vehicles with the 4 speed automatic transmission.
Correction
To repair the # 4 injector/EGR harness, repair the wire using Service Manual procedures and install a 60 mm (2.5 in.) section of flexible polypropylene
or nylon conduit (suitable for high temperature, underhood usage) over the harness to prevent further damage. Make sure that EGR and injector wires are
both captured by the conduit. Tape the ends of the conduit.
To repair the main engine wire harness chafing against the transaxle oil cooler line bracket, repair the wire using Service Manual procedures and use a
plastic tie strap to secure the main engine wire harness to the battery cables. This will locate the engine wire harness away from the cooler line bracket at
the transaxle.
