Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Address Fuel Delivery Issues

Inspect Fuel Pump:
- Remove the fuel pump access panel (if applicable).
- Check the fuel pump operation by listening for the pump activating while turning the ignition key to the "ON" position (do not start the engine).
- If the pump is not operational, replace it with a new one.
Replace Fuel Filter:
- Locate the fuel filter, typically along the fuel line.
- Disconnect the fuel lines using appropriate tools.
- Replace the old filter with a new one and reconnect the lines securely.

3. Inspect and Replace Air Filter

Remove Air Filter Housing:
- Unscrew or unclip the air filter housing.
- Carefully remove the old air filter and check for dirt or blockages.
Install New Air Filter:
- Insert the new air filter into the housing.
- Reattach the housing and ensure it is secured properly.

4. Check and Replace Spark Plugs and Ignition Coils

Remove Spark Plugs:
- Use a socket wrench to remove the spark plugs.
- Inspect for wear or carbon buildup.
Replace Spark Plugs:
- Install new spark plugs, ensuring they are torqued to manufacturer specifications (typically around 15-20 Nm).
Inspect Ignition Coils:
- If any spark plugs appear damaged, replace the corresponding ignition coil.

5. Test Drive and Recheck Systems

Reconnect the negative battery terminal.
Start the engine and allow it to idle.
Take the vehicle for a test drive to ensure power loss issue is resolved.
