Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a level surface with the ignition off.
Disconnect the negative battery terminal.

2. Battery Inspection and Replacement

Tools Required: Multimeter, wrench/socket set
Steps:
1. Use a multimeter to measure the battery voltage; if below 12.4 volts, charge or replace the battery.
2. Clean battery terminals with a wire brush and ensure they are tight.
3. If the battery is faulty, remove it by loosening the hold-down bracket and disconnecting the positive terminal first, followed by the negative terminal.

3. Starter Motor Testing and Replacement

Tools Required: Socket set, jumper wire
Steps:
1. Locate the starter motor; it is typically mounted near the transmission.
2. Test the starter motor by connecting a jumper wire from the battery positive terminal to the starter terminal; listen for engagement.
3. If the starter does not engage, remove it by disconnecting the electrical connectors and the mounting bolts.
4. Replace with a new starter motor, ensuring all connections are secure.

4. Ignition Switch and Wiring Inspection

Tools Required: Screwdriver set, multimeter
Steps:
1. Remove the steering column cover to access the ignition switch.
2. Use a multimeter to check for voltage at the ignition switch when turned to the start position.
3. If no voltage is present, replace the ignition switch.
4. Inspect wiring harness for any visible damage or loose connections.
