Is there something so much different about a 2009 Fit's wiring compared to a 1996-2000 Civic that means you can't just cut the ground to the fuel injector relay? I did that five years ago on my 1998 Civic. The worst thing that has ever happened has been a switch failure after tens of thousands of uses. All the switch failure required for repair was reconnecting the ground wire with a buttsplice in the car and driving home using key off for engine off coasting. Took less than 5 mins to repair, and failure only happened because of my novice design flaws. Wire failed once. Switch failed once. I moved the wires so they would get less stress from the shifter knob's movements, and later I got a more robust switch. No new issues.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
