If the clearance is less than 0.02 inch and the starter whines, shims can be added to increase the clearance. If the clearance is greater than 0.06 inches and the starter whines, shims can be removed to reduce the clearance.

If the starter motor spins but the engine is not cranking, it means that the overrunning clutch in the starter motor is slipping. In this case, the motor must be removed from the engine for replacement.

If the starter motor spins but the engine does not crank, the overrunning clutch in the starter motor may be slipping, and you'll need to replace the motor.

The steps for removing the starter in a 2WD vehicle are as follows:Disconnect the negative battery cable.

Perform the following checks and inspections when troubleshooting a starting circuit issue:Ensure the battery cable clamps are clean and securely fastened at the battery terminals.Assess the condition of the battery cables and replace any damaged ones.Test the battery's condition and replace it with a new battery if it fails any tests.Examine the wiring and connections associated with the starter motor.Check the tightness of the starter motor mounting bolts.Inspect the relevant fuses in the engine compartment fuse box and replace any blown fuses.

To install the new starter motor assembly, you should perform the installation in reverse order, ensuring that the starter mounting bolts are tightened to the specified torque.

The steps for removing the starter in a 4WD vehicle are as follows: Disconnect the negative battery cable. Raise the front of the vehicle and support it securely on jack stands. Removing the wheel (left wheel on 2.2L models, right wheel on 4.3L V6 models) may facilitate better access. Remove the skid plate. On 2.2L models, take off the front driveshaft. In some early models, you may need to raise the engine/transmission with a floor jack under the transmission and remove the transmission cross member for access to the starter motor bolts. If equipped, remove the starter heat shield. From underneath the vehicle, disconnect the solenoid wire and battery cable from the terminals on the solenoid. Remove the starter mounting bolts. Take out the starter motor, noting the location of any spacer shim(s), if present.

If the starter motor cranks the engine at a slow speed, ensure that the battery is charged and all terminal connections are clean and tight. Additionally, check if the engine is partially seized or has the wrong viscosity oil, as these factors can also cause slow cranking.

To diagnose slow cranking, run the engine until it reaches normal operating temperature, then stop the engine, disconnect the coil wire from the distributor cap, and ground it on the engine. Connect a voltmeter positive lead to the starter motor terminal of the solenoid and the negative lead to the ground. Crank the engine and take voltmeter readings as soon as a steady figure is indicated, making sure not to let the starter motor turn for more than 15 seconds at a time. A reading of 9 volts or more, with the starter motor turning at normal cranking speed, is normal. If the reading is 9 volts or more but the cranking speed is slow, the motor is faulty. If the reading is less than 9 volts and the cranking speed is slow, the solenoid contacts are likely burned.
