Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is in a safe location, parked on a level surface.
Disconnect the negative battery cable to prevent any electrical shocks.

2. Battery Inspection and Replacement

Tools Required: Multimeter, battery terminal cleaner, wrench set.
Clean the battery terminals using a battery terminal cleaner if corrosion is present.
If the battery voltage is low (below 12.4 volts) or the load test fails, replace the battery.
- Remove the positive (+) cable first, followed by the negative (-) cable.
- Install the new battery by connecting the positive (+) cable first, then the negative (-) cable.
Ensure all connections are tight and secure.

3. Starter Relay and Fuse Check

Tools Required: Wrench set, test light or multimeter.
Locate the fuse box (usually under the dashboard or in the engine bay).
Remove the starter relay and test it for continuity using a multimeter.
Replace the relay if it is faulty.
Check the starter fuse for continuity and replace if blown.

4. Starter Motor Inspection

Tools Required: Socket set, multimeter.
If the battery and relay are good, access the starter motor by removing any necessary components (like the air intake or splash shield).
Check the wiring to the starter motor for corrosion or damage.
Test the starter motor by applying direct battery voltage to it. If it does not engage, replace the starter motor.

5. Reassembly and Connection

Reinstall any components removed during the inspection.
Reconnect the negative battery cable.
Ensure all tools are removed from the engine bay.
