Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is in park or neutral with the parking brake engaged.

2. Battery and Connections Inspection

Sub-steps:
1. Clean the battery terminals using a wire brush and a mixture of baking soda and water if corroded.
2. Reconnect the battery terminals securely, starting with the positive terminal followed by the negative terminal.

3. Starter Relay and Fuse Replacement

Sub-steps:
1. Locate the fuse box under the hood and remove the cover.
2. Identify the starter relay and the relevant fuses by consulting the owner's manual.
3. Replace any blown fuses with ones of the same amperage.
4. Replace the starter relay if testing showed it was faulty.

4. Fuel System Check

Sub-steps:
1. If the fuel pump was silent, access the fuel pump relay and check for proper operation.
2. If necessary, replace the fuel pump relay to ensure proper fuel delivery.

5. Starter Motor Testing

Sub-steps:
1. If the engine still does not start, access the starter motor.
2. Test the starter motor using a multimeter to check for voltage at the starter terminal when the ignition key is turned.
3. If there is voltage but the starter does not engage, replace the starter motor.
