Rough morning startup

Hey guys i had a question for y'all. The past 2 mornings the car has been having long and rough start ups. Any input? Battery tested okay and i'm guessing it might be the fuel pump?

It could be low pressure in the fuel lines, which would probably lead as you had expected, to a defective fuel pump. Does it stall sometimes, or smell like gas?

Dirty MAF?
Dirty throttle bodies?
Dirty/clogged fuel filter?

Bunch of things could be the culprit

Best thing to do is probably record a vid and upload it.

Will do. I'll check the battery one more time, but as for now i'm waiting for the oil to cool down.

Have you tried getting the acc on before starting the car? Don't put your foot on the brake or clutch (depending auto or manual) press the start button twice, after the fuel pump runs for 2-3 seconds (yes you can hear some little wizard working in the engine) then start the car. I don't have your issue, but it significantly improves cold starts regardless.

Isn't it under warranty or have you already went through the limit?

I would second the opinion of cleaning the throttle bodies. After I cleaned mine the car ran weird for 15 minutes and I thought I screwed it up but after that it's felt smoother.
