Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrench set, battery terminal cleaner, and safety goggles.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Battery Inspection

Remove the battery terminals (negative first, then positive).
Clean any corrosion from the terminals and battery posts using a terminal cleaner.
Reconnect the battery terminals securely (positive first, then negative).

3. Battery Test

Use a multimeter to measure the battery voltage.
- If voltage is below 12.4V: Charge or replace the battery.
If the battery is good, proceed to test the starter.

4. Starter Motor Check

Locate the starter motor (typically near the transmission).
Use a wrench to connect the battery directly to the starter motor terminal.
If the starter engages: The issue may be with the ignition switch or wiring.
If it does not engage: Replace the starter motor.

5. Fuel System Check

Access the fuel pump relay and check if it’s functioning properly.
If the relay is operational, listen for the fuel pump when the ignition is turned on.
If there's no sound, replace the fuel pump.

6. Ignition System Check

Remove and inspect spark plugs for wear or fouling.
Replace spark plugs if they are worn or damaged.
Check ignition wires and coils for signs of wear and replace if necessary.
