Solution

1. Preparation

Gather tools and parts.
Disconnect the negative terminal of the battery.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal.
2. Clean any corrosion from the terminals using a battery terminal cleaner or a mixture of baking soda and water.
3. Test the battery with a multimeter; if it’s below 12.4 volts, recharge or replace it.
4. If replacing, install a new battery ensuring correct polarity (positive to positive, negative to negative).

3. Starter Relay Inspection

Sub-steps:
1. Locate the starter relay in the fuse box (refer to the owner's manual for exact location).
2. Remove the starter relay and visually inspect for damage.
3. Swap it with a similar relay to test functionality.
4. If the engine still does not turn over, proceed to check the starter motor.

4. Starter Motor Testing

Sub-steps:
1. Locate the starter motor under the vehicle (usually near the transmission).
2. Disconnect the electrical connector and the battery cable from the starter.
3. Use a multimeter to check for voltage at the starter terminal when the ignition key is turned to the start position.
4. If there is voltage but the starter does not engage, replace the starter motor.

5. Ignition Switch and Neutral Safety Switch Check

Sub-steps:
1. Remove the steering column cover to access the ignition switch.
2. Test for continuity at the ignition switch with a multimeter when the key is turned.
3. Check the neutral safety switch by attempting to start the vehicle in both the "Park" and "Neutral" positions.
