Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, fuel pressure gauge.
Ensure safety by wearing gloves and eye protection.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Battery Inspection and Replacement

Inspect Battery Terminals:
- Clean any corrosion from the battery terminals using a wire brush.
- Tighten the connections securely.
Test and Replace Battery (if needed):
- Reconnect the battery and test the voltage again.
- If the voltage is low or the battery is more than 3-5 years old, replace it with a new battery of the same specifications (typically a Group 24F).

3. Starter Motor Check

Remove Starter Motor:
- Disconnect the positive terminal from the starter motor.
- Unbolt the starter motor using a socket set.
Test and Replace Starter Motor (if needed):
- Use a multimeter to check the resistance of the starter motor.
- If resistance is outside manufacturer specifications, replace the starter motor.

4. Fuel System Inspection

Check Fuel Pump:
- Reconnect the battery and turn the ignition to the "ON" position without starting the engine to activate the fuel pump.
- Use a fuel pressure gauge to check the pressure; it should be within manufacturer specifications (approximately 30-40 psi for most Camry models).
Replace Fuel Pump (if needed):
- If pressure is low, remove the fuel pump assembly from the fuel tank and replace it with a new unit, ensuring all seals are properly installed.
