Things to look at in order of likely hood:

1) Check 2nd spark plug on the driver side from the front (#3), make sure it is fully seated, you should get 1-2 clicks out of the coil pack and 1 click on spark plug

2) Check spark plug for proper gap (make sure it didn't get dropped or something weird), swap plug to different position if issue continues to see if it follows plug and then replace

3) Check coil pack wiring, check for full insertion then remove and check for broken pin lock(s) causing recessed contacts when inserted

I've had #1 and #3 happen
