Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before starting any work.

2. Battery Check

Tools Required: Multimeter
Measure the battery voltage. If it’s below 12.4 volts, charge the battery or replace it if defective.

3. Starter Motor Test

Tools Required: Jumper wire
Locate the starter motor and connect the jumper wire between the battery positive terminal and the starter solenoid terminal to see if it engages. If it does, the starter is functional.

4. Ignition Switch Inspection

Tools Required: Screwdriver
Remove the steering column cover. Inspect the ignition switch for wear and tear. Replace it if necessary.

5. Fuel System Check

Tools Required: Fuel pressure gauge
Check for fuel pressure at the fuel rail. If pressure is low or absent, inspect the fuel pump and relay.

6. Reassemble and Test

Reconnect all components and ensure all connections are secure.
