Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge.
Ensure the vehicle is parked on a level surface, and set the parking brake. Disconnect the negative terminal of the battery before starting any repairs.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to test the battery voltage. If it reads below 12.4V, charge or replace the battery.
Clean Battery Terminals
- Disconnect the battery terminals. Clean the terminals and cable ends with a wire brush to remove any corrosion.
Reconnect Battery
- Reconnect the battery terminals and ensure they are tight.

3. Starter and Ignition System Check

Inspect Starter Motor
- Remove the starter motor from the vehicle (usually located near the transmission).
- Check for physical damage or corrosion on terminals.
Test Starter Operation
- Connect the starter directly to a battery to see if it engages. Replace if it fails to operate properly.

4. Fuel System Inspection

Check Fuel Pump
- Turn the ignition to the "ON" position without starting the engine and listen for the fuel pump's humming sound.
- If absent, test the fuel pump relay and replace if faulty.
Test Fuel Pressure
- Attach a fuel pressure gauge to the fuel rail and turn the ignition on. Ensure the pressure meets manufacturer specifications (usually around 30-40 psi).

5. Reassemble and Final Checks

After all inspections and repairs, reassemble any components removed.
Ensure all bolts and connections are tightened to manufacturer specifications.
