Bnr s4 installed now my car won’t start without jumping the starter

[Clay46]

So I got my bnr s4 in along with these mods ported intake manifold, xspower turbo manifold, HTP 3.5” intake, corksport injector seals, Damond motorsports rear motor mount, turbo smart dual port blowoff valve, autotech high pressure fuel pump internals, cpe catted downpipe, grimmspeed 3 Port electronic boost controller, cx racing front mount intercooler, guardian angel v3, and I think a 3bar map sensor ( came with the manifold and I forgot to ask, it is a Bosch sensor). I got it all together and when I tried to start it nothing happens, all my interior lights turn on and everything but I’m not getting anything to the starter. So I jumped the starter and once I get it started it dies in about 2-3 seconds. I even have a mechanic helping me with this and he doesn’t know. All the fuses tested ok. He has almost run out of ideas. Just looking for some helpful ideas as to why it is doing this. I also have no throttle response, I can’t just press the gas to keep it running.
