Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the vehicle to sit for a while if it has been recently driven.

2. Battery Inspection

Sub-steps:
1. Remove the battery terminals (negative first, then positive).
2. Clean the terminals and battery posts with a wire brush to remove corrosion.
3. Reconnect the terminals (positive first, then negative).
4. If the battery is weak (below 12.4 volts), replace it with a new battery of the correct specifications.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor under the vehicle.
2. Disconnect the wiring harness and power cable from the starter.
3. Use a multimeter to test continuity and resistance in the starter motor.
4. If the starter is faulty, replace it with a new starter, ensuring all connections are secure.

4. Fuel System Check

Sub-steps:
1. Locate the fuel pump relay and test it using a multimeter.
2. If faulty, replace the fuel pump relay.
3. Inspect the fuel lines for leaks or blockages.
4. Replace the fuel filter if clogged.
5. If fuel pressure is low, consider replacing the fuel pump.
