Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, and safety gloves.
Ensure the vehicle is parked on a flat surface and the ignition is turned off.

2. Battery Inspection

Sub-steps:
1. Disconnect the negative battery terminal using a socket set.
2. Clean any corrosion from battery terminals with a wire brush.
3. Reconnect the terminals securely, ensuring a tight fit.

3. Starter Motor Testing

Sub-steps:
1. Locate the starter motor (typically under the vehicle near the transmission).
2. Disconnect the electrical connector from the starter motor.
3. Use jumper cables to apply power directly to the starter to see if it engages.
4. If the starter does engage, replace the ignition switch; if it does not, replace the starter motor.

4. Fuel Pump Inspection

Sub-steps:
1. Locate the fuel pump relay in the fuse box.
2. Swap it with another relay of the same type to test functionality.
3. If the pump is faulty, access the fuel tank by removing the rear seats or accessing the fuel pump access panel.
4. Replace the fuel pump as necessary.

5. Final Assembly

Sub-steps:
1. Reassemble any components removed during inspection.
2. Ensure all electrical connections are secure.
3. Reconnect the negative battery terminal.
