Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and the engine is cool.

2. Address Fuel Supply Issues

Inspect Fuel Pump
- Tools Required: Fuel pressure gauge
- Sub-steps:
  - Locate the fuel pump relay and fuse; check for continuity.
  - Connect the fuel pressure gauge to the fuel rail.
  - Turn the ignition to the "ON" position without starting the engine and check the pressure.
  - If pressure is low, replace the fuel pump.
Replace Fuel Filter
- Tools Required: Wrench set, screwdrivers
- Sub-steps:
  - Relieve fuel system pressure.
  - Disconnect fuel lines from the filter and remove the old filter.
  - Install the new filter, ensuring correct orientation, and reconnect fuel lines.

3. Inspect and Replace Ignition Components

Check Spark Plugs
- Tools Required: Spark plug socket, torque wrench
- Sub-steps:
  - Remove spark plugs using the spark plug socket.
  - Inspect for wear or carbon buildup; replace if necessary.
  - Torque new spark plugs to manufacturer specifications.
Test Ignition Coils
- Tools Required: Multimeter
- Sub-steps:
  - Disconnect the ignition coil connectors.
  - Measure the resistance of each coil and compare with specifications.
  - Replace any coils that are out of spec.

4. Check for Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner
Sub-steps:
- Use a smoke machine to check for leaks in vacuum hoses.
- Alternatively, spray carburetor cleaner around potential leak areas and listen for RPM changes.
- Replace any damaged hoses or gaskets.
