Solution

1. Preparation

Tools Required: Multimeter, socket set, jumper cables, wrench set, battery terminal cleaner.
Disconnect the negative battery cable to prevent electrical shock.

2. Battery Inspection

Clean the battery terminals with a battery terminal cleaner to remove any corrosion.
Ensure the battery connections are tight and secure.
If the battery voltage is low, charge the battery or replace it if it fails the load test.

3. Starter Relay and Fuse Check

Locate the fuse box and identify the starter relay.
Remove the starter relay and inspect it for damage; if damaged, replace it.
Check the associated fuses for continuity and replace any that are blown.

4. Starter Test

Reconnect the negative battery cable.
Use a multimeter to check for voltage at the starter solenoid while someone turns the ignition key to the start position.
If there is no voltage, the ignition switch may be faulty or there may be an issue with the wiring.

5. Replace Starter (if necessary)

If the starter solenoid does not engage, remove the starter.
Tools Required: Socket set, torque wrench.
Disconnect the battery again before removing the starter.
Unbolt the starter from its mounting, and carefully remove it from the engine bay.
Install the new starter, ensuring it is properly aligned and bolted in place.
Torque the starter bolts to the manufacturer’s specifications (refer to the repair manual).
