Solution

1. Preparation

Gather tools: multimeter, socket set, OBD-II scanner, battery terminal cleaner, and jumper cables.
Ensure the vehicle is parked safely and the engine is off.

2. Battery Inspection and Replacement

Check Battery Voltage
- Use a multimeter to measure the battery voltage. A healthy battery should show around 12.6 volts or more.
Clean Battery Terminals
- Disconnect the battery terminals (negative first, then positive). Use a battery terminal cleaner to remove any corrosion.
Test Battery Health
- If the voltage is low, use a battery tester to check the health. If it’s failing, replace the battery with a new one.
- Parts Required: New battery if replacement is necessary.

3. Starter and Fuel System Check

Inspect Starter Motor
- Locate the starter motor and check its connections for tightness and corrosion.
- Use jumper cables to bypass the ignition switch and directly power the starter to see if it engages.
Check Fuel Pump Functionality
- Turn the ignition key to the "on" position (without starting) and listen for the fuel pump activation sound. If silent, inspect the fuel pump relay and fuse.
- If the fuel pump is faulty, replace it.
- Parts Required: Fuel pump if replacement is necessary.

4. Final Checks

Reset Error Codes
- After repairs, use the OBD-II scanner to clear any error codes.
Reconnect Battery
- Reconnect the battery terminals (positive first, then negative) ensuring they are tight.
