Solution

1. Preparation

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

2. Inspect and Test the Battery and Alternator

Use a multimeter to check the battery voltage; it should read around 12.6 volts when fully charged.
Start the engine and test the alternator output; it should read between 13.5 to 14.5 volts.
If voltage readings are outside these ranges, replace the battery or alternator as needed.

3. Fuel System Inspection

Check the fuel pump fuse and relay for continuity.
If the fuse is intact, test the fuel pump operation by turning the ignition to the "on" position without starting the engine; you should hear the pump prime.
If there’s no sound, replace the fuel pump.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold.
Clean the throttle body using throttle body cleaner and a soft cloth or brush.
Reinstall the throttle body and ensure all connections are secure.

5. Ignition System Check

Remove spark plugs and inspect for wear or fouling.
Replace spark plugs if they show signs of damage or are worn beyond specifications.
Test the ignition coils with a multimeter to ensure they are functioning correctly; replace any faulty coils.
