Sunday August 21st, 2023: With the previous data in had I went about to bypass the FPCM. As I didn't want to commit to this 100%, I just did the normal bypass loop on the wiring. After testing this with the Ford wiring intact (minus the Fuel Pump Control Module) I found that key on turned on the pump and it was on all the time the key was on. So that part was a success.
Moving on I went on to temporarily bypass the fuel pump relay in the battery junction box and connected a wire to the Holley pump trigger and inserted it in the triggered side of the relay wiring. Now with the Key on, the Holley primed the pump for 5 seconds per setup as expected. Key on also added 52lbs of pressure to the rails.
Now it was time to test the whole thing, needless to say, it now cranks and runs off the Holley controlling the pump. Now I just need to hard wire all of this in and get to where I can tweak the tune and drive the car. After I started this and was checking the trans fluid when I went from park to reverse to neutral then drive, the second time around it actually Died going into Nuetral. Not sure why that happened but...
