Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Inspect Battery and Alternator

Sub-steps:
1. Reconnect the battery and use a multimeter to check the battery voltage (should be around 12.6V when off).
2. Start the engine and check the voltage again (should be between 13.7V and 14.7V).
3. If the voltage is low, replace the alternator.

3. Fuel System Check

Tools Required: Fuel pressure gauge
Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition on (without starting the engine) and check the pressure (should meet manufacturer specifications).
3. If pressure is low, inspect the fuel pump and replace if necessary.

4. Ignition System Repair

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the ignition coils and inspect for damage or wear.
2. Replace any faulty coils or worn spark plugs.
3. Reinstall components and torque to manufacturer specifications.

5. Address Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Replace any damaged hoses and ensure all connections are secure.

6. Final Assembly

Reconnect the battery and start the engine.
Ensure all tools are removed from the engine bay.
