Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical shock.

2. Inspect and Test Fuel Pump

Tools Required: Fuel pressure gauge
Sub-steps:
1. Locate the fuel pump access panel (if applicable) or remove the rear seat to access the fuel pump.
2. Connect the fuel pressure gauge to the fuel line.
3. Turn the ignition to the "ON" position without starting the engine and check the fuel pressure reading. Refer to the vehicle's manual for the correct pressure specification.
4. If pressure is low, consider replacing the fuel pump.

3. Check Electrical System

Tools Required: Multimeter
Sub-steps:
1. Reconnect the battery and use a multimeter to check the battery voltage; it should read around 12.6 volts.
2. Start the engine and check the voltage at the alternator; it should read between 13.5 to 14.5 volts.
3. Inspect battery cables and grounds for corrosion or loose connections. Clean or tighten as needed.

4. Inspect Ignition System

Tools Required: Spark plug socket, torque wrench
Sub-steps:
1. Remove the spark plugs and inspect for wear or fouling.
2. Replace any damaged spark plugs with OEM specifications.
3. Using a torque wrench, tighten the spark plugs to the manufacturer's specified torque.

5. Reconnect and Test Drive

Reconnect the battery.
Start the engine and allow it to reach operating temperature.
Test drive the vehicle under various conditions to check for stalling issues.
