Default Hard Start on Fresh Rebuild

Like in the title. It takes several cranks to get it started. Also, my MAP sensor and air charge temperature pigtails are broken and I dont think they're plugged in all the way. I have new ones on the way but I'm curious if this would cause my hard start? Thanks for the advise in advance.

Shouldn't cause a hard start. Fuel pressure okay? Plug wires crossed?

That was my first thought too, fuel pressure.

Aftermarket throttle bodie? If everything above has been checked, hold the throttle open and try starting the car. Goodluck!
