2001 infinity I30 V6, 3.0 motor.

I just put another motor in my 2001 infinity i30. Initially the car wont start then i had to replace the fuel pump and the computer. I had the car programmed then it started but kept on cutting off by itself. At this point it wont start but it is pumping the fuel to the injectors. When i used OBD check engine light reader, it states that i need to replace the throttle body which i did and still it wont start. What could be the problem. Someone suggested i replace the body control module whatever that is. Any ideas please? Thanks
