YJ Cold start problem

Jeep Information

My YJ wont start for about 20 min. When it does start it sputters a few times like the idle is off. I just had the fuel sending unit replaced and also changed spark plugs, wires, fuel filter, fuel regulator, air pressure sensor and also took off the throttle body and cleaned it up. Would the IAC or MAP sensor make it idle funny and not start when cold? Im running out of options...any help is greatly appreciated
