5.7l hemi problem help please

I got my 5.7 put in my 68 dart but I have a few problems. 1st prob is the injectors wnt fire while its cranking. I give it a shot of either and it will start and the injectors fire fine once its running. Not sure what sensors would enable it not to fire while cranking. 2nd is I have no throttle responce from the pedal to the throttle body. I think that mite be a wireing prob but I'm wondering if the 2 problems might be related. Let me knw if any of you knw anything bout the 5.7 thanks

If you are wired into the factory ignition switch/wiring there is a "run" circuit and a "start" circuit. You may find the problem there. As far as the throttle response, wiring issue.

This is an option:
