Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, fuel pressure gauge, and safety glasses.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove battery terminals (negative first, then positive).
- Clean any corrosion with a wire brush and a solution of baking soda and water.
Test Battery:
- Use a multimeter to measure voltage; if below 12.4 volts, replace the battery.
Replace Battery:
- If replacement is needed, install a new battery ensuring correct polarity.
- Reconnect terminals (positive first, then negative).

3. Starter Motor Inspection and Replacement

Remove Starter Motor:
- Disconnect the wiring harness and the battery cable from the starter motor.
- Remove the starter motor mounting bolts using a socket set.
- Carefully pull out the starter motor from its housing.
Test Starter Motor:
- Use a multimeter to check for continuity and resistance.
- If defective, replace it with a new starter motor.
Reinstall Starter Motor:
- Position the new starter motor in place and secure it with mounting bolts.
- Reconnect the wiring harness and battery cable.

4. Fuel System Check

Inspect Fuel Pump:
- Remove the fuel pump fuse and check for continuity.
- If faulty, replace the fuel pump.
Check Fuel Filter:
- Inspect and replace the fuel filter if it is clogged or damaged.
