Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery
- Remove any corrosion from the terminals using a wire brush.
- Ensure that the battery terminals are tight and secure.
Replace Battery (if necessary)
- Use a multimeter to check voltage; if below 12.4 volts, consider replacing.
- Remove the battery by loosening the hold-down bolt and disconnecting the positive terminal first, followed by the negative terminal.
- Install the new battery by connecting the positive terminal first, then the negative terminal. Tighten the hold-down bolt to manufacturer specifications.

3. Fuel System Inspection

Fuel Pump Test
- Turn the ignition to the "ON" position without starting the engine, and listen for the fuel pump. If no sound is heard, the pump may be faulty.
Fuel Pressure Check
- Attach a fuel pressure gauge to the fuel line. Turn the ignition on and check that the pressure is within the specified range (typically around 40-50 PSI for a Camry).
- If pressure is low, inspect for leaks in the fuel line or replace the fuel pump if necessary.

4. Ignition System Service

Inspect Spark Plugs
- Remove spark plugs using a socket wrench and inspect for wear or fouling.
- Replace spark plugs if they are worn or damaged, ensuring to gap them correctly as per manufacturer specifications.
Check Ignition Coils
- Inspect ignition coils for cracks or damage. Replace any faulty coils to ensure proper ignition.
