Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Address Fuel System Issues

Check Fuel Pump Operation
- Turn the ignition key to the "On" position without starting the engine.
- Listen for the fuel pump operation; it should run for a few seconds.
- If the pump does not engage, check the fuse and relay for the fuel pump.
Replace Fuel Filter (if applicable)
- Locate the fuel filter along the fuel line.
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the fuel lines (using line wrenches) and remove the old filter.
- Install the new fuel filter, ensuring correct flow direction, and reconnect fuel lines.

3. Inspect and Replace Ignition Components

Inspect Spark Plugs
- Remove the spark plugs using a socket wrench.
- Check for signs of wear, carbon buildup, or damage.
- Replace spark plugs with OEM or equivalent parts if necessary.
Test Ignition Coils
- Disconnect the ignition coil connectors and remove the coils.
- Use a multimeter to test coil resistance; replace any coils that are out of specification.

4. Air Intake System Inspection

Inspect Air Filter
- Remove the air filter housing cover and check the air filter for dirt and debris.
- Replace the air filter if it is dirty or clogged.
Check Intake Hoses
- Visually inspect all intake hoses for cracks or leaks.
- Replace any damaged hoses to prevent unmetered air from entering the engine.
