So I had some time at work this weekend to think over my wiring. Compared it to the Holley EFI techs wiring recommendation, drew it out the way he stated. Then drew it out the way I had it.
Compared the two....same.
The ECU signal can't be switched to ground. All the other I/Os can, but this one in particular is designed to be a 12v signal programmed to prime the pump and then power it once it sees RPM.
So now it's time to get the meter back out and see where the wheels came off.
Going to check that the 12v from the ECU is actually 12 (pump primed weak, maybe it can't pull the contacts in), going to check the built in fuel circuit relay, and then re-test the new relays and make sure they weren't wired wrong from Magnafuel

How dare you! Lol
That's like saying if my grandmother had wheels, she'd be a shopping cart.
