Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, fuel pressure gauge.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety while working on the electrical components.

2. Address Fuel System Issues

Check the fuel pump fuse and relay for continuity and replace if necessary.
If the fuel pump is not functioning:
- Remove the fuel pump access cover (if applicable).
- Disconnect the fuel lines and electrical connectors from the fuel pump.
- Remove the fuel pump assembly from the fuel tank.
- Install a new fuel pump and reassemble the components in reverse order.
Check and replace the fuel filter if clogged.

3. Inspect Ignition System

Remove the spark plug wires and inspect for damage or corrosion.
Replace spark plugs if worn or fouled:
- Remove old spark plugs using a socket wrench.
- Gap the new spark plugs to the manufacturer's specifications.
- Install the new spark plugs and reconnect the wires.
Test ignition coils with a multimeter for proper resistance and replace if necessary.

4. Check Air Intake System

Inspect the air filter and replace if dirty or clogged.
Ensure the intake manifold and throttle body are clean and free from debris.
Reconnect any loose or damaged vacuum hoses.

5. Reconnect and Test

Reconnect the negative battery terminal.
Start the engine and allow it to reach normal operating temperature.
Monitor for any abnormal sounds or check engine light illumination.
