Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative terminal of the battery to ensure safety while working.

2. Battery Inspection and Replacement

Sub-step 1: Inspect the battery for any signs of damage or corrosion on terminals.
Sub-step 2: Clean the terminals with a battery cleaning brush and a mixture of baking soda and water if corrosion is present.
Sub-step 3: If the battery voltage is low (below 12.4 volts), consider charging the battery or replacing it if it fails to hold a charge.

3. Starter Relay and Fuse Check

Sub-step 1: Locate the fuse box under the dashboard and check the fuses related to the starting system for continuity. Replace any blown fuses.
Sub-step 2: Locate the starter relay in the fuse box and swap it with a similar relay to check if the issue resolves.

4. Starter Motor Inspection

Sub-step 1: If the battery and fuses are good, access the starter motor, typically located near the transmission.
Sub-step 2: Disconnect the wiring harness from the starter and check for any signs of damage or loose connections.
Sub-step 3: Test the starter motor by applying direct battery voltage to see if it engages. If it does not, replace the starter motor.

5. Neutral Safety Switch Check

Sub-step 1: Locate the neutral safety switch on the transmission.
Sub-step 2: Inspect its wiring and connections for any damage.
Sub-step 3: If faulty, replace the neutral safety switch.
