Cold start / hard start issue

Having a hard start issue and was wondering if anyone had any ideas. I will be taking it to the shop in a week or so, just curious if anyone else solved it or had similar issues. Started last summer randomly and has been continual since

symptoms are as follows:

-Very long start/struggle to start, will crank for about 5-6 seconds just barely about to start but wont start
-Press start to shut off
-Press start again, fires up instantly
-Runs completely fine after it starts
-Every other start after the cold start is completely fine, instantly fires up, unless I let it sit overnight, then I have the same issue.

Battery is brand new, so that's not it. No codes. ICV, TA's all that stuff is new. I just put some techron injector cleaner in, will see if that does anything, will also have the shop check the injectors for any issues. Was also reading a thread stating it could be the LPFP sensor, but without codes? Or a leaky injector?
