Solution

1. Preparation

Gather all tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before working on it.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pump relay and turn the ignition to the "ON" position to relieve fuel pressure.
2. Reconnect the fuel pump relay and connect a fuel pressure gauge to the fuel rail.
3. Turn the ignition to the "ON" position again and check the pressure reading against manufacturer specifications (typically around 30-50 psi).
4. If pressure is low, inspect the fuel filter and replace if necessary.
5. Test the fuel pump operation by listening for it to prime when the ignition is turned on.

3. Electrical System Check

Sub-steps:
1. Use a multimeter to check the battery voltage; it should be around 12.6 volts with the engine off.
2. Inspect all ground connections for corrosion or looseness.
3. Check the alternator output when the engine is running (should be between 13.5 to 14.5 volts).
4. Replace corroded or damaged battery cables if necessary.

4. Ignition System Inspection

Sub-steps:
1. Remove and inspect the spark plugs for wear or fouling.
2. Check ignition coils for proper function using a multimeter to measure resistance.
3. Replace any faulty ignition components as needed.

5. Vacuum Leak Detection

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Use a smoke machine or carburetor cleaner to detect leaks; observe for changes in engine RPM.
3. Replace any damaged hoses.
