Solution

1. Preparation

Gather tools including a multimeter, socket set, and screwdriver.
Ensure the vehicle is in park or neutral and the parking brake is engaged.

2. Battery Check

Sub-steps:
1. Disconnect the negative (-) terminal of the battery.
2. Clean any corrosion from the terminals using a wire brush.
3. Reconnect the terminals securely.
Tools Required: Wire brush, socket set
Safety Warnings: Always disconnect the negative terminal before working on the electrical system.

3. Starter Motor Inspection

Sub-steps:
1. Locate the starter motor (usually near the engine block).
2. Disconnect the wiring harness from the starter.
3. Use a multimeter to test for power at the starter terminal when the ignition is turned to start.
4. If no power is present, trace back to the ignition switch and relay.
Tools Required: Multimeter, socket set

4. Ignition Switch Testing

Sub-steps:
1. Remove the ignition switch cover.
2. Disconnect the electrical connector from the ignition switch.
3. Use a multimeter to test for continuity when the key is turned to the start position.
4. Replace the ignition switch if no continuity is detected.
Tools Required: Screwdriver, multimeter

5. Fuel Pump Check

Sub-steps:
1. Turn the ignition to the "ON" position without starting the engine.
2. Listen for the fuel pump to activate (a faint whirring sound).
3. If silent, check the fuel pump fuse and relay; replace as needed.
Tools Required: None specifically required for listening, but multimeter may be used for further testing.
