Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Battery Inspection and Replacement

Tools Required: Multimeter, wrench set
Check the battery voltage. If it is below 12.4V, charge or replace the battery.
Inspect and clean the battery terminals using a wire brush.
If the battery is old (over 3-5 years), consider replacing it with a new one.

3. Starter Motor Testing and Replacement

Tools Required: Wrench set, screwdriver
Test the starter motor by connecting it directly to a power source. If it does not engage, replace the starter motor.
Remove the starter motor by unbolting it from the engine mount and detaching the electrical connectors.
Install the new starter motor by reversing the removal process and ensuring all bolts are torqued to manufacturer's specifications.

4. Fuel System Check

Tools Required: Fuel pressure gauge
If the fuel pump was not functioning, check the fuel pump relay and fuse.
Replace the fuel pump if necessary by removing the fuel tank and accessing the pump assembly.
Replace the fuel filter if it is clogged during the inspection.
