I means sometimes my car doesn't start because it doesn't want too. Sometime I disconnected the stock air box and just leave the air duct open almost like a short ram and it will crank up most of the time but sometimes like today it just didn't want to crank up and about 5 mins later mashing on the throttle while turning the key over it turned on

Air filter is new not even a month old.

Fuel pump? It used to be when I'd park at an incline as my driveway is back in Miami it wouldn't crank and i suspected a weak fuel pump not delivering the fuel, but this is assuming. And I'm on flat parking space where I live now.

Any advice or suggestions or potential causes?

As always Rep for good answers!

And battery is at 550 CCA ALT is at around 14.13 volts and starter is great too.
