Solution

1. Preparation

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

2. Inspect Fuel System

Check fuel pump relay:
- Locate the fuel pump relay in the fuse box; replace if faulty.
Examine fuel pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition on (do not start) and check for adequate pressure (typically 30-60 psi).
- If pressure is low, replace the fuel pump.
Inspect fuel filter:
- Remove the fuel filter and check for clogs.
- Replace the filter if it appears dirty or clogged.

3. Inspect Ignition System

Remove spark plugs:
- Use a socket set to remove the spark plugs.
- Inspect for wear or carbon build-up; replace if necessary.
Test ignition coils:
- Use a multimeter to check the resistance of each coil.
- Replace faulty coils as needed.

4. Resolve Vacuum Leaks

Visual inspection:
- Examine all vacuum hoses for cracks or disconnections; replace any damaged hoses.
Smoke test:
- If necessary, perform a smoke test to identify hidden leaks.

5. Reconnect Battery and Test

After all checks and repairs, reconnect the battery.
Start the engine and allow it to idle to ensure stability.
