Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Test Battery

Sub-steps:
- Use a multimeter to check battery voltage (should be around 12.6V).
- Clean any corrosion from the battery terminals using a wire brush.
- Ensure battery cables are tight and secure; replace if damaged.

3. Fuel System Inspection

Sub-steps:
- Remove the fuel pump access cover (if applicable) and check connections.
- Use a fuel pressure gauge to measure the fuel pressure while the engine is running. Refer to service manual for specifications.
- If pressure is low, replace the fuel pump.

4. Check Ignition System

Sub-steps:
- Remove spark plugs and examine for wear or fouling; replace as necessary.
- Test ignition coils using a multimeter; replace any faulty coils.

5. Airflow Component Assessment

Sub-steps:
- Inspect and clean the mass airflow sensor using MAF cleaner.
- Replace the air filter if dirty or clogged to ensure proper airflow.

6. Reassemble and Test

Reconnect the battery terminal securely.
Start the engine and ensure it runs smoothly without shutdowns.
