Solution

1. Preparation

Tools Required: Multimeter, socket set, wrench set, battery terminal cleaner, safety gloves, safety goggles.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Battery Inspection

Clean the battery terminals using a battery terminal cleaner.
Ensure the connections are tight; if corrosion is present, remove and clean thoroughly.
If the battery voltage is low, recharge or replace the battery.

3. Starter Relay Check

Locate the starter relay in the fuse box.
Remove the relay and inspect for any signs of burning or damage.
Swap it with a similar relay from the fuse box to test functionality.

4. Starter and Wiring Inspection

Locate the starter motor and check for any loose connections or damaged wires.
Use a multimeter to measure the voltage at the starter solenoid when attempting to start the engine.
If there is no voltage, trace back to the ignition switch and check for continuity.

5. Replace Starter (if necessary)

If the starter is determined to be faulty, detach the wiring from the starter.
Remove the starter mounting bolts using a socket set.
Install the new starter by reversing the removal steps, ensuring all connections are secure.
