FiTech EFI system

I tried turning the key on and off multiple times, and tried cranking multiple times. Each time before I turned it to start, I would let the fuel pump cycle on/off and wait for the injectors to click. When cranking it almost fires, sometimes multiple times one after the other, but does not start. If it were carburetors and not efi, I would squirt some fuel into it, that kind of almost start. There is fuel initially at start, pulled air cleaners to check, and I squirted a small amount of fuel into it just to make sure, made no difference.
Unable to locate any compromised wire, I only jacked the motor up a few inches to change the mounts, did not stretch any wires out or crush- checked them after it wouldn't start. Checked the coil wires as well and connections, no issues found there.
No bulkhead power connector or old fuse box, power directly from new modern fuse box, new charge wire from alternator. Power hub next to battery so everything isn't connected to the battery terminal.
Rpms on handheld, coil new, I know new electrical parts can fail, but it sparks.
For what it's worth, whenever I disconnected/connected the battery there were no sparks, I would attribute that to no more crappy wiring and poor grounds, all fuses good.

I started it last night w/o issue, disconnected battery, changed the rubber motor mounts out for polys, took me no time, motor still warm even though it wasn't running very long. Completely stumped.
