Solution

1. Preparation

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

2. Battery and Connections

Disconnect the negative battery terminal using a socket wrench.
Clean the battery terminals and cable ends with a wire brush to remove any corrosion.
Reconnect the battery terminals, ensuring they are tight and secure.

3. Replace the Battery (if necessary)

If the battery voltage is low, remove the battery using a socket set.
Install a new battery, ensuring it matches the specifications for your vehicle.
Tighten the battery terminals to the recommended torque setting (typically 10-12 ft-lbs).

4. Starter Motor Check

If the starter is malfunctioning, remove it using a socket set.
Inspect for wear or damage and test with a multimeter for proper operation.
Replace the starter motor if it fails the test.

5. Fuel System Check

If the fuel pump is not operational, check the fuel pump relay and fuse.
Replace the fuel filter if it is clogged, ensuring to relieve fuel system pressure before removal.
If the fuel pump is faulty, replace it following the manufacturer's instructions.
