Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Battery Inspection and Replacement

Sub-steps:
1. Remove the battery terminals, starting with the negative terminal first, followed by the positive terminal.
2. Clean any corrosion from the terminals using a wire brush and a mixture of baking soda and water.
3. Test the battery for charge and capacity; if the voltage is low (below 12.4V) or it fails a load test, replace the battery with a new one.
4. Reinstall the new battery, connecting the positive terminal first, then the negative.

3. Starter Motor Check

Sub-steps:
1. Locate the starter motor and visually inspect it for any signs of damage or corrosion.
2. Test the starter motor by connecting it directly to the battery to see if it engages; if it does not, replace the starter motor.

4. Fuel System Check

Sub-steps:
1. Use a fuel pressure gauge to check for adequate fuel pressure; refer to the service manual for the correct specifications.
2. If fuel pressure is low, inspect the fuel pump and fuel filter for blockages or failures; replace as necessary.

5. Engine Coolant Temperature Sensor Replacement

Sub-steps:
1. Locate the engine coolant temperature sensor, disconnect the wiring harness, and remove the sensor.
2. Install a new sensor, ensuring it is properly seated, and reconnect the wiring harness.
