"So, I pulled the correct fuse, let the car run.... and run... and run. I finally turned it off after it ran for roughly 15 minutes without that fuse. I tried again by pulling the fuses for the main AND pre-pump. Still kept on running."
I'm guessing your 240 is between '83 and '88, with LH 2.2 FI. (Always include the year along with the model. There are differences.)
The only active FI fuse in the panel is #4, for the tank pump, and the car will run without it. Fuse #6 is not wired to anything in U.S. LH 2.2 cars. I believe it is used for K-jet in other markets, such as Malaysia.
The main LH FI fuse is the 25A blade fuse by the coil. It feeds everything in the FI system, and pulling it while running results in an immediate stall-out.
This "fuse depressurizing" myth bites us all eventually, and comes up here fairly often. It doesn't work because there is no specific Pump or Relay fuse. And pulling any fuel-related fuse results in an immediate stall — with no appreciable depressurizing.
