Solution

1. Preparation

Gather tools and parts before starting the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Fuel System Issues

Fuel Pump Check
- Locate the fuel pump fuse in the fuse box and inspect it for damage; replace if necessary.
- Use a fuel pressure gauge to check the fuel pressure at the fuel rail. Compare with manufacturer specifications.
Fuel Filter Replacement
- If pressure is low, replace the fuel filter.
- Disconnect the fuel lines using a line wrench, and replace the filter with a new one, ensuring to bleed any residual fuel pressure.

3. Inspect and Replace Ignition Components

Spark Plug Inspection
- Remove spark plugs using a spark plug socket and inspect for wear or fouling; replace if necessary.
Ignition Coil Testing
- Use a multimeter to test the resistance of each ignition coil. Replace any that fall outside the manufacturer specifications.

4. Check Air Intake and Vacuum Lines

Air Filter Replacement
- Remove the air intake cover and replace the air filter with a new one if it is dirty or clogged.
Inspect Vacuum Lines
- Visually inspect and manually check vacuum lines for cracks or loose connections; replace any damaged lines.

5. Reconnect Battery and Test

Reconnect the battery terminals and ensure they are tight.
Start the engine and allow it to idle to check for any abnormal sounds or further stalling.
