So after my last slew of issues this appears to be at the root.

Gsl-se na 13b. Ms2 v 3. Zeal. Stock cas. S5 injectors rails and intake.

With the key in the run position my injectors are always open. I checked all my wiring for shorts. Checked the injector driver IC and its good. Checked the mosfets. All good. Any clue what could be going on? Only the primary bank is open I'm reading 270 k ohms at the injector signal wire with the key on.

The only thing that can be is a short or bad mosfets... Have you tried the MS on the stim to make sure the LEDs aren't on all the time?

The led blink while cranking and running with fuel pump off. If it were always on would my ignition signal I'm pulling from d14 not work either? All 4 of my ignition signals are good. Running coil on plug rx8 mode.

New development. Car will start and run on both rotors for a sec using starting fluid and no gasoline. If I turn the fuel pump on I only run on rotor 1 but rotor 2 is not running. I verified I have good spark @ all 4 coils. I am going to take the manifold off AMD check my injector resistance and solder joints on the harness.

check that the injectors themselves are working correctly.

They seem to be. I checked em with a meter. All good. Car starts and runs but pig rich. I dropped my req fuel from0 to 4. Still rich. Wideband still reads 10.5-11:1. Could too high fuel pressure be my issue? Car is same config from when it was running fine a few mo ago when I took it apartt for a trans swap.

Yes. upping the fuel pressure will inject more fuel as well as having a more powerful pump will also allow more fuel to be injected as flow rates differ.
