Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery negative terminal using a wrench.

2. Battery Replacement (if necessary)

Tools Required: Wrench, battery terminal cleaner
Remove the positive and negative cables from the battery terminals using a wrench.
Lift the old battery out of the battery tray.
Clean the battery tray and terminals with a terminal cleaner.
Place the new battery into the tray and reconnect the positive cable first, followed by the negative cable.
Ensure the connections are tight and secure.

3. Starter Motor Testing (if necessary)

Tools Required: Multimeter, jumper wires
Locate the starter motor, usually found near the engine block.
Use a multimeter to check for voltage at the starter motor terminals when the ignition is turned to the start position.
If voltage is present but the starter does not engage, remove the starter motor.
Inspect for any physical damage, and if necessary, replace the starter motor with a new unit.
Reinstall the starter motor and reconnect wires.

4. Final Checks

Reconnect the battery negative terminal.
Ensure all connections and components are securely fastened.
Test the ignition again to see if the vehicle starts.
