Solution

1. Preparation

Tools Required: Multimeter, OBD-II scanner, socket set, jump leads.
Ensure the vehicle is in a safe location and the parking brake is engaged.

2. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Remove the positive terminal and unbolt the battery from its tray.
3. Inspect the battery for physical damage or swelling.
4. If the battery is faulty, replace it with a new one of the same specifications.
5. Reinstall the battery, reconnect the terminals (positive first, then negative), and ensure they are tight.

3. Starter Motor Testing and Replacement

Sub-steps:
1. Locate the starter motor, typically near the transmission.
2. Disconnect the electrical connections from the starter motor.
3. Use a multimeter to test for power at the starter terminal when the ignition is turned to the start position.
4. If no power is detected, further investigate wiring and ignition switch.
5. If power is present but the starter does not engage, remove the starter motor by unbolting it.
6. Replace with a new starter motor, ensuring all connections are secure and properly torqued.

4. Fuel System Check

Sub-steps:
1. If the fuel pump was suspected, remove the fuel pump fuse and check its condition.
2. If blown, replace the fuse and attempt to start the vehicle.
3. If the fuel pump is faulty, access the fuel tank, disconnect the fuel lines, and remove the fuel pump assembly.
4. Install a new fuel pump and reassemble the fuel lines and tank securely.
