Three different starters are used for the 1996 models. Refer to the following table to determine the correct starter application.

Although the PG-250 and PG-260 motor starters look similar, the PG-260 is lighter and uses a different solenoid, which requires a different battery positive cable, due to the terminal locator. Both PG starter motors have an anodized metal (gold colored) finish. The starter attachment and pinion-to-flywheel clearance is the same for both starters, but because of the different battery positive cable attachments, the PG starter motors are not interchangeable. The SD-260 starter motor is black and is only used on the Caprice sedan with the 4.3L L99 engine.

When the ignition switch is moved to the start position, a start request is sent to the theft deterrent module. If correct PASS-Key II® resistance is detected and the vehicle is in PARK or NEUTRAL, then the theft deterrent module will energize the starter enable relay. The starter enable relay will send battery voltage to the starter solenoid switch. As the solenoid is energized, the starter shift lever moves into crank position, causing the starter drive pinion to engage the flywheel ring gear. After engagement, the starter solenoid switch will close the motor main contacts, which results in cranking of the engine. When the engine starts, the starter's overrunning clutch protects the armature from excessive speed until the switch is opened, at which time the solenoid switch plunger spring causes the pinion to disengage. To prevent excessive overrun, the ignition switch should be opened immediately when the engine starts.
