Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, and safety glasses.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Fuel System Inspection

Check Fuel Pump:
1. Disconnect the negative battery terminal to prevent electrical shorts.
2. Locate the fuel pump relay and remove it.
3. Use a multimeter to test the fuel pump for power and ground continuity.
4. If necessary, replace the fuel pump with a new unit (ensure to relieve fuel pressure before removal).
Inspect Fuel Filter:
1. Locate the fuel filter and check for clogs or restrictions.
2. If dirty, replace the fuel filter with a new one, ensuring the directional flow is correct.

3. Ignition System Repair

Check Spark Plugs:
1. Remove spark plugs using a socket wrench.
2. Inspect plugs for wear, carbon buildup, or damage.
3. Replace any defective spark plugs with the manufacturer-recommended parts.
Examine Ignition Coils:
1. Test each ignition coil with a multimeter for proper resistance.
2. Replace any faulty ignition coils.

4. Air Intake System Check

Inspect Air Filter:
1. Remove the air filter and check for dirt and obstructions.
2. Replace with a new air filter if necessary.
Check for Vacuum Leaks:
1. Inspect vacuum hoses for cracks or disconnections.
2. Replace any damaged hoses to ensure proper air intake.
