Solution

1. Battery Inspection and Replacement

Sub-steps:
1. Disconnect the negative terminal of the battery.
2. Clean any corrosion from battery terminals using a mixture of baking soda and water.
3. If the battery voltage is below 12.6 volts, replace the battery with a new one.
Tools Required: Wrench set, battery terminal cleaner.
Safety Warnings: Wear gloves and safety glasses to protect against battery acid.

2. Starter Motor Replacement

Sub-steps:
1. Disconnect the battery negative terminal.
2. Remove the starter motor by unbolting it from the engine block.
3. Disconnect the electrical connectors from the starter.
4. Install the new starter motor and reconnect the electrical connectors.
5. Bolt the starter motor back to the engine block using the correct torque specifications (typically around 30-40 ft-lbs).
Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure the vehicle is securely lifted and supported if access to the starter requires working underneath.

3. Fuel System Inspection and Repair

Sub-steps:
1. Inspect the fuel pump relay and fuse, replacing them if faulty.
2. Replace the fuel filter if it appears clogged or has not been changed per maintenance schedule.
3. If fuel pressure was low, replace the fuel pump.
Tools Required: Fuel pressure gauge, socket set, torque wrench.
Safety Warnings: Release fuel system pressure before disconnecting fuel lines to prevent spray.
