Solution

1. Preparation

Gather tools: Multimeter, socket set, jumper wires, and cleaning supplies.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection

Sub-step 1: Use a multimeter to measure battery voltage. If below 12.4 volts, proceed to charge or replace the battery.
Sub-step 2: Clean the battery terminals and cable connections with a wire brush to remove corrosion.
Sub-step 3: Reconnect the battery terminals securely.

3. Starter Motor Testing

Sub-step 1: Locate the starter motor (usually near where the engine and transmission meet).
Sub-step 2: Use jumper wires to bypass the ignition switch by connecting the positive terminal on the starter to the positive battery terminal. Ensure the vehicle is in park or neutral.
Sub-step 3: If the starter engages and the engine cranks, replace the ignition switch or the starter relay.

4. Wiring and Fuses Check

Sub-step 1: Inspect the starter relay and replace if necessary (consult vehicle manual for location).
Sub-step 2: Check all related fuses in the fuse box and replace any that are blown.
Sub-step 3: Inspect wiring to the starter motor for wear, corrosion, or breaks, repairing or replacing as necessary.
