Toyota 28100-66060 Starter Assembly

To remove the starter/Starter Solenoid assembly, start by detaching the battery's negative terminal and ensure the correct activation code for the stereo's anti-theft system. Remove the engine compartment's Car Batteries and disconnect the cruise control assembly. Detach electrical connectors from the starter/solenoid assembly. Then, remove starter motor mounting bolts, including the top one, and the upper section's bracket if needed. Installation is the reverse of removal.

Before diagnosing starter issues, ensure the Car Batteries is fully charged. Check if the starter motor turns when the switch is operated. Verify clean and secure cables at battery and starter solenoid terminals. If the motor spins but the engine doesn't crank, replace the starter motor due to a slipping over-running clutch. If the solenoid clicks but the motor doesn't operate, investigate battery, solenoid contacts, starter motor, or a seized engine as possible causes. If no solenoid sound is heard, check battery, fusible link, starter relay, or solenoid. Test the solenoid with a jumper lead. If the starter motor works, the solenoid is fine, else investigate the ignition switch, Neutral start switch, or wiring. If the motor cranks abnormally slowly, confirm charged battery and tight connections. A partially seized engine or wrong viscosity oil can cause slow cranking. Perform voltage tests during cranking. A reading of nine volts or more at normal cranking speed is normal. Less than nine volts with slow cranking indicates possible issues with solenoid contacts, starter motor, battery, or connections.
