Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off and cooled down.
Disconnect the negative battery terminal to avoid any electrical shorts.

2. Battery Inspection and Replacement

Inspect Battery:
- Remove the battery from the vehicle.
- Clean the terminals with a wire brush if corrosion is present.
- Use a multimeter to check battery voltage; replace if below 12.4 volts.
Replace Battery:
- If replacement is necessary, install a new battery that meets OEM specifications.
- Connect the positive terminal first, then the negative terminal.
- Ensure connections are tight and clean.

3. Starter Motor Testing and Replacement

Test Starter Motor:
- Reconnect the battery and attempt to start the engine; listen for any clicking sounds.
- If the starter fails to engage, proceed to remove it.
Replace Starter Motor:
- Disconnect the wiring from the starter motor.
- Remove the bolts securing the starter to the engine block.
- Install the new starter motor and tighten bolts to manufacturer's torque specifications (typically around 10-15 Nm).
- Reconnect the wiring.

4. Fuel System Check

Inspect Fuel System:
- Check the fuel pump relay and fuse for faults.
- Use a fuel pressure gauge to test if the fuel pressure is within specification (usually 3-4 bars).
- Replace fuel filter if it is clogged or if fuel pressure is low.

5. Coolant Temperature Sensor Check

Inspect and Replace Sensor:
- Locate the engine coolant temperature sensor.
- Disconnect the wiring harness and remove the sensor.
- Install a new sensor and reconnect the wiring.
