Solution

1. Preparation

Gather tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Ensure the car is in park (or neutral) and the ignition is off.

2. Check and Replace Battery

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Inspect the battery for physical damage or leakage.
3. If the battery voltage is low, charge or replace the battery using a compatible battery (Group Size 35).
Tools Required: Multimeter, wrench/socket set for battery terminals.
Safety Warnings: Avoid short-circuiting battery terminals; wear safety goggles.

3. Inspect and Replace Starter Relay

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for location).
2. Remove the relay and visually inspect for damage.
3. Swap with a known good relay and attempt to start the vehicle.
Tools Required: Relay puller or needle-nose pliers.

4. Test and Replace Starter

Sub-steps:
1. Remove the starter motor by disconnecting the battery terminals again (if not already done).
2. Disconnect the wiring harness and the mounting bolts.
3. Test the starter by connecting it directly to the battery; if it does not engage, replace the starter.
4. Install the new starter by reversing the removal steps.
Tools Required: Socket set, torque wrench for starter mounting bolts.
Safety Warnings: Ensure the battery is disconnected during installation.
