Can't get my 92 Honda Civic hatchback to run right

My 92 Civic hatchback has a 98 CRV B20 motor in it, just recently put in. But for some reason it will not run right, if you give it gas it sputters like it's misfiring or getting to much fuel or not enough and you hardly have any power. I have put everything new on it new distributor rotor button new plugs and wires new TPS sensor new throttle body, new idle air control valve, new temp sensor, new stock injectors, new fuel pump, new fuel pump regulator it don't have a gauge on it but it's new. I know there's probably more I putting you on it but I can't remember right now. But we've come to the end and want to just sell it because we cannot figure out why you can't just push the gas and take off like a real B20 is supposed to do. Is there anybody out there that can give me some more ideas or help me out anyway at all cuz I really don't want to get rid of the the car I just put too much money into it. Any ideas guys I just can't think of anything anymore. This is the car and the motor that we just put in that's not me in the picture that's my boyfriend
