GMC Rally Wagon 3500 ProblemsCheck Engine Light and Misfire Due to Stuck Fuel Injectors

There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.
The alternator may fail causing the battery to go dead. The charge light on the dash may or may not illuminate. The alternator may also develop an abnormal noise. A failed alternator will require replacement.
