Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, wrenches, and safety gloves.
Ensure the vehicle is in a well-ventilated area and parked on a level surface.

2. Battery Inspection and Replacement

Disconnect the negative battery terminal to prevent electrical shorts.
Clean battery terminals using a wire brush and a baking soda solution if corrosion is present.
Reconnect the battery terminals and ensure they are tight.
If the battery voltage is low, replace the battery with a compatible one, ensuring it meets the specifications for the Honda Accord.

3. Fuel System Check

Inspect the fuel pump relay and fuse for any failures.
If necessary, remove the fuel pump access panel and test the fuel pump operation; replace if faulty.
Change the fuel filter if it hasn’t been replaced within the manufacturer’s recommended interval.

4. Ignition System Service

Remove the spark plugs using a socket wrench and inspect for wear or carbon buildup.
Replace spark plugs if they are worn or fouled; use OEM recommended specifications.
Check ignition coils for proper function using a multimeter; replace any faulty coils.

5. Starter Motor Inspection

If the starter is suspected, remove it from the vehicle following manufacturer recommendations.
Test the starter motor with a bench test to check for proper functionality; replace if it fails the test.
