Solution

1. Preparation

Gather necessary tools and parts.
Ensure safety by disconnecting the battery.
Allow the engine to cool if it has been recently operated.

2. Battery Inspection and Replacement

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

3. Starter Motor Check

Remove Starter Motor:
- Disconnect wiring harness and remove mounting bolts.
- Carefully pull the starter motor out.
Test Starter:
- Use jumper cables to connect directly to the starter motor to verify functionality.
Replace Starter:
- If faulty, install a new starter motor, ensuring proper alignment and torque settings on bolts.

4. Fuel System Inspection

Check Fuel Pump:
- Turn the ignition to the ON position; listen for the fuel pump priming sound.
Replace Fuel Filter:
- If blocked, replace the fuel filter according to manufacturer specifications.
Inspect Fuel Lines:
- Check for leaks or kinks in the fuel lines.

5. Ignition System Check

Inspect Spark Plugs:
- Remove spark plugs and check for wear or fouling.
Replace Spark Plugs:
- If necessary, install new spark plugs with the correct gap as per manufacturer specifications.
Test Ignition Coils:
- Check for spark using a spark tester; replace any faulty ignition coils.
