Solution

1. Preparation

Tools Required: Socket set, multimeter, battery terminal cleaner, screwdriver, torque wrench.
Ensure the vehicle is in park (automatic) or neutral (manual).
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the terminals and cable ends with a battery terminal cleaner.
3. Reconnect the terminals, ensuring they are tight.

3. Starter Motor Replacement (if necessary)

Sub-steps:
1. Locate the starter motor (usually found near the engine block).
2. Disconnect the electrical connectors from the starter.
3. Remove the mounting bolts securing the starter.
4. Remove the old starter and install the new starter in reverse order, tightening the bolts to the manufacturer’s specified torque (usually around 20-30 ft-lbs).
5. Reconnect the electrical connectors.

4. Ignition Switch Inspection

Sub-steps:
1. Remove the steering column cover using a screwdriver.
2. Locate the ignition switch and check for secure connections.
3. If defective, replace the ignition switch by disconnecting the wiring harness and removing the mounting screws.
