Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent accidental starts.

2. Inspect Fuel System

Check Fuel Lines:
- Use a visual inspection to look for cracks or leaks in fuel lines.
- Replace any damaged lines.
Test Fuel Injectors:
- Disconnect each fuel injector connector.
- Use a multimeter to check for proper resistance specifications.
- Replace any faulty injectors.

3. Check Engine Components

Inspect Spark Plugs:
- Remove spark plugs using a socket set.
- Check for signs of fouling; replace plugs if necessary.
- Ensure proper gap setting according to manufacturer specifications.
Examine Air Filter:
- Remove the air filter housing cover.
- Inspect the air filter for clogging; replace if dirty.

4. Verify Fuel Pressure

Connect Fuel Pressure Gauge:
- Locate the fuel rail and connect the gauge to the service port.
- Start the engine and check the fuel pressure; it should meet manufacturer specifications.
- If pressure is low, consider replacing the fuel pump.

5. Reassemble and Test

Reconnect all components and fuel lines.
Reconnect the battery.
Start the engine and allow it to reach operating temperature.
