Fuel injector replaced and now crank but no start

Replaced injectors did it by the Haynes book correct. Except the whole security pass lock thing before disconnecting the negative battery cable. I could not do so because of an aftermarket stereo previous owner put in. I had to have the car sit over night ripped apart until the injectors came. I have no fuel pressure in my rails now.I checked the fuses and all of my connectors and lines I had recently taken off. I can not here the fuel pump kick in when I turn to on. So I jumped under put my hand on the plastic tank and still no humming nothing. Beginning to think it’s the fuel pump or something to do with that security system any ideas?
