Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, fuel pressure gauge, and a wrench set.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Battery Inspection and Replacement

Check Battery Voltage: Use a multimeter to measure the battery voltage (should be around 12.6 volts).
- If below 12 volts, consider charging or replacing the battery.
Clean Battery Terminals: Disconnect the battery and clean the terminals with a wire brush.
Reconnect Battery: Reconnect the battery terminals and ensure they are tight.

3. Fuel System Inspection

Check Fuel Pump: Turn the ignition to the "On" position without starting the engine and listen for a humming sound.
- If not heard, test the fuel pump relay and wiring.
Test Fuel Pressure: Using a fuel pressure gauge, connect it to the fuel rail and check the pressure specifications (typically around 40-50 psi for Camry).
- If pressure is low, replace the fuel pump.

4. Ignition System Inspection

Inspect Spark Plugs: Remove spark plugs and check for wear or deposits.
- Replace if necessary.
Test Ignition Coils: Use a multimeter to check the resistance of each ignition coil.
- Replace any faulty coils.

5. Starter Motor Check

Inspect Starter Motor: Check for any loose connections or corrosion on the starter terminals.
Test Starter Functionality: If the starter is clicking, tap it gently with a hammer while attempting to start. If it starts, replace the starter.
