my Honda Civic 10th Generation (2016-2021) has a hard time starting in the morning

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, torque wrench, and cleaning supplies.
• Ensure the car is parked on a level surface and the engine is turned off.

2. Battery Maintenance

1. Disconnect the negative terminal of the battery to prevent electrical shorts.
2. Clean the battery terminals and cable connections with a wire brush and battery cleaner.
3. Reconnect the terminals securely, starting with the positive terminal followed by the negative.

3. Battery Replacement (if necessary)

1. If the battery voltage is low or the battery is old (over 3-5 years), consider replacing it.
2. Remove the battery hold-down bracket using a socket wrench.
3. Carefully lift the old battery out of the tray and place the new battery in.
4. Reattach the battery hold-down bracket, ensuring it is tight (typically 10-15 ft-lbs torque).

4. Starter Inspection

1. If the starter is suspected to be faulty, remove it by disconnecting electrical connections and removing bolts (usually 12-14 mm).
2. Test the starter outside the vehicle by applying power directly from a jump box or battery.
3. If the starter does not engage, replace it with a new starter.

5. Fuel System Check

1. If the fuel pump is suspected to be the issue, access the fuel pump relay or fuse and check for continuity.
2. If faulty, replace the fuel pump relay and/or fuel pump as necessary.
3. Ensure the fuel lines are not blocked and the fuel filter is replaced regularly.
