Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a flat surface and set the parking brake.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Test the Battery

Use a multimeter to check the battery voltage; it should be around 12.6 volts for a fully charged battery.
Clean battery terminals and cable connections with a wire brush if corrosion is present.
If the battery voltage is low, recharge or replace the battery.

3. Fuel System Inspection

Check the fuel pump relay and fuse for continuity.
If the fuel pump is not operating, replace it.
Replace the fuel filter if it is clogged or hasn't been changed in a while.

4. Ignition System Repair

Remove and inspect spark plugs; replace them if they are worn or fouled.
Test ignition coils with a multimeter for resistance; replace any faulty coils.
Ensure all wiring connections to the ignition system are secure.

5. Reassemble and Test

Reconnect the battery.
Start the engine to check if the hard start issue has been resolved.
