Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal.

2. Battery Inspection

Tools Required: Multimeter
Check the battery voltage. It should be above 12.4 volts.
Clean any corrosion from battery terminals and tighten connections.
If the battery voltage is low, replace the battery.

3. Fuel System Check

Tools Required: Fuel pressure gauge
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check the pressure. It should be within the manufacturer's specifications (about 30-50 psi).
If the pressure is low, check the fuel pump and replace if necessary.

4. Spark Plug Inspection

Tools Required: Spark plug socket, torque wrench
Remove the spark plugs and inspect for wear or deposits.
Replace any damaged or worn spark plugs with OEM parts, and torque to the manufacturer's specifications (typically around 13 ft-lbs).

5. Starter Motor Test

Tools Required: Multimeter, socket set
Locate the starter motor and check the voltage at the terminal when the ignition is turned to the "START" position.
If voltage is present but the starter does not engage, consider replacing the starter motor.

6. Fuel Pump Relay Check

Tools Required: Multimeter
Locate the fuel pump relay in the fuse box.
Test the relay for continuity and replace if faulty.
