Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to cool down if it was recently operated.

2. Battery Inspection and Replacement

Check Battery Condition:
- Use a multimeter to measure battery voltage. If below 12.4 volts, consider replacement.
Clean Battery Terminals:
- Remove the connectors and clean terminals with a wire brush. Reconnect securely.
Replace Battery (if necessary):
- Remove the old battery using a socket set. Install the new battery and connect terminals.

3. Starter Motor Inspection and Replacement

Test Starter:
- Check if the starter engages when power is supplied. If not functioning, remove it.
Replace Starter:
- Disconnect wiring from the starter and remove mounting bolts using a socket set. Install the new starter and reconnect wiring.

4. Fuel System Inspection and Repair

Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail. If pressure is below specifications, inspect the fuel pump.
Replace Fuel Pump (if necessary):
- Drain the fuel tank, remove the fuel pump assembly, and install a new pump.

5. Ignition System Inspection and Repair

Inspect Spark Plugs:
- Remove spark plugs using a spark plug socket. Replace if worn or fouled.
Test Ignition Coils:
- Use a multimeter to check resistance. Replace any faulty coils.
