Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Clean Battery Connections

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the terminals and battery posts with a wire brush to remove corrosion.
3. Reconnect the terminals securely (positive first, then negative).
Tools Required: Wire brush, wrench set.

3. Test or Replace the Battery

Sub-steps:
1. If the voltage is below 12.4 volts, recharge the battery or replace it if it cannot hold a charge.
2. Use a battery load tester to confirm the battery's health.
Tools Required: Battery charger or new battery, load tester (optional).

4. Inspect and Replace the Starter Relay

Sub-steps:
1. Locate the fuse box and identify the starter relay.
2. Remove the starter relay and replace it with a known good relay.
3. If the vehicle starts, the previous relay was faulty.
Tools Required: Relay puller or pliers.

5. Check and Replace the Starter Motor (if necessary)

Sub-steps:
1. Disconnect the wiring harness and battery terminal from the starter motor.
2. Remove the mounting bolts securing the starter motor to the engine block.
3. Install the new starter motor, ensuring proper alignment and torque the bolts to manufacturer specifications (typically around 15-20 ft-lbs).
4. Reconnect the wiring harness and battery terminal.
Tools Required: Socket set, torque wrench.
