With ground to the pgm-fi unit disabled, the guino injector signal might be sort-of floating, so there is a chance a different kill switch will fix it.

It might need a pulldown resistor too for more accuracy if it isn't pulled low by default, or otherwise a couple bias resistors so it reads correctly when the fi is hooked up or not.
Sounds complicated, lol. I'm not exactly the engineering type, so I eagerly anticipate the results of your testing to see how I should modify my setup.
