Help! installed greddy intake manifold on rb25det and wont run now.

[GTS-T 240]

so i installed my greddy manifold with my q45 throttle body and now the car will only crank over. put a node light on a few injectors and they all flash really low if that. fuel pump doesnt seem to prime as hard or loud as it did before the intake was installed. so im not sure if its the q45 tbody or if its a ground somewhere that i missed but my boss and i have been all over the engine bay and not found any bad grounds. so i dont really know if it the tbody stuck in clear flood mode or something. i have no idea at this point i really want to get my car out of my work thought, so please help me. thanks alot. also its an rb25det series 2, walbro fuel pump.
