Will it start with the aid of starting fluid?

It is flooding when it starts after it warms up it flooded until I clear it out I have a snap-on scanner hooked up no codes I am watching pids the ect reads close to ambieant temp the manofold temp sens reads correct also I am wondering if the injector or pressure regulator is the problem it is 5 degrees here today it is acting up but still no codes all my pids look good I worry about the barrow reading it is 4.89 the map reading is 1.65 barrow seems high however I had a good map sensor but it didnt help. Any ideas

You can disconnect the sensors and see if it works that way the vehicle will not read those sensors and run from the computer pre set deffinition.
