Solution

1. Preparation

Gather necessary tools: OBD-II scanner, multimeter, jumper wires, socket set, and torque wrench.
Ensure the vehicle is in a safe location, with the ignition off.
Disconnect the battery to prevent accidental shorts.

2. Battery Inspection

Sub-steps:
1. Inspect the battery terminals for any corrosion. Clean them using a wire brush if necessary.
2. Tighten any loose connections.
3. Reconnect the battery and retest the voltage.

3. Starter System Repair

Sub-steps:
1. Locate the starter motor (typically near the transmission).
2. Remove the electrical connector from the starter.
3. Use jumper wires to connect the starter directly to the battery to test its operation.
4. If the starter does not engage, replace the starter motor.
5. If it engages but does not crank the engine, inspect the ignition switch and the starter relay.

4. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and check its operation by swapping with a similar relay (if available).
2. If the relay is functional, check the fuel pump itself by accessing the fuel tank.
3. Disconnect the fuel line and turn the ignition to the "ON" position to see if fuel is being pumped.
4. If there is no fuel flow, replace the fuel pump.

5. Reassembly

Sub-steps:
1. Reconnect all electrical connections securely.
2. Ensure all components removed for access are reinstalled correctly.
3. Reconnect the battery terminal and ensure it is tight.
