Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.

2. Check Fuel System

Inspect Fuel Pump Relay:
- Locate the fuel pump relay in the fuse box.
- Remove the relay and test it with a multimeter for continuity.
Test Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position (do not start) to check for proper fuel pressure (should be within manufacturer specifications).
- If pressure is low, proceed to replace the fuel pump.

3. Inspect and Clean Fuel Injectors

Remove Fuel Injectors:
- Disconnect the fuel lines and electrical connectors from the injectors.
- Carefully remove the injectors from the intake manifold.
Clean Injectors:
- Use a fuel injector cleaning kit to clean each injector.
- Reinstall the injectors with new O-rings.

4. Check for Vacuum Leaks

Inspect Hoses:
- Visually inspect all vacuum hoses for cracks or disconnections.
- Replace any damaged hoses.
Test with Smoke Machine:
- Use a smoke machine to identify any leaks in the intake system.

5. Reconnect and Test

Reassemble Components:
- Reinstall the fuel injectors and reconnect all hoses and electrical connections.
Reconnect Battery:
- Reattach the negative battery terminal.
Start Engine:
- Start the engine and observe if it continues to run.
