Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection

Tools Required: Multimeter, wire brush, wrench set
Clean battery terminals with a wire brush to remove corrosion.
Tighten any loose connections at the battery posts.
If the battery voltage is low, charge or replace the battery as needed.

3. Starter Motor Test

Tools Required: Jumper wires, multimeter
Locate the starter motor, usually found on the engine block near the transmission.
Connect jumper wires from the battery to the starter motor terminals directly.
If the starter engages and the engine cranks, the starter is functional; if not, replace the starter motor.

4. Ignition Switch Check

Tools Required: Screwdriver set
Remove the steering column cover to access the ignition switch.
Use a multimeter to test for continuity when the key is turned to the start position.
If there is no continuity, replace the ignition switch.

5. Fuel System Check

Tools Required: Fuel pressure gauge
Locate the fuel pump relay and check if it is functioning.
Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to ON and check for proper fuel pressure; if absent, replace the fuel pump.
