Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery to ensure safety.
2. Remove the battery from the vehicle using a socket set.
3. Clean the battery terminals and cable connections with a wire brush.
4. Test the battery with a multimeter; replace if voltage is below 12.4 volts or if it’s more than 3-5 years old.

2. Starter Motor Check and Replacement

Sub-steps:
1. Reconnect the battery.
2. Locate the starter motor under the vehicle.
3. Disconnect the electrical connections to the starter.
4. Remove the starter motor using a socket set.
5. Install a new starter motor, ensuring all connections are secure.

3. Fuel System Inspection

Sub-steps:
1. Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Reinstall the fuse and connect a fuel pressure gauge to the fuel rail.
3. Turn the ignition to the "ON" position and check fuel pressure; it should meet the manufacturer's specifications.
4. If pressure is low, inspect and replace the fuel pump as necessary.
