I think we need to see that we are getting power to them first and then go from there.

Attached circuit diagram is my circuit implementation that I have built for my '75 conversion. The pink-black wire is used to power up auxiliary gauges (WBO, Tach, etc). You can omit it if not needed for your build.
Since you can get engine to run by dumping fuel into TB it indicates that you have ignition, but ECM is not firing injectors. Two possibilities - ECM is not getting power during cranking or injectors do not get 12 volts during cranking.
Got to run - will continue.
