Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a safe, well-ventilated area.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Battery Testing and Replacement

Sub-steps:
1. Reconnect the battery and use a multimeter to measure the voltage.
2. If the voltage is low, jump-start the vehicle or replace the battery if necessary.
  - Tools Required: Multimeter, jumper cables, battery replacement (if needed).
  - Safety Warning: Always wear safety goggles when working with batteries.

3. Inspect and Test Starter Motor

Sub-steps:
1. Locate the starter motor and inspect wiring for damage.
2. Disconnect the starter motor electrical connector.
3. Use a multimeter to test for power at the starter when the ignition is turned to the start position.
4. If power is present, replace the starter motor.
  - Tools Required: Socket set, multimeter, replacement starter motor (if necessary).

4. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and inspect it for continuity.
2. If defective, replace the fuel pump relay.
3. If the relay is functional, check the fuel pump by removing the access panel and testing with a multimeter.
4. Replace the fuel pump if it fails the test.
  - Tools Required: Socket set, multimeter, replacement fuel pump (if necessary).
