Poll: Easiest way to disable spark and fuel?
Main question: What's the easiest way to disable spark and fuel? Let's say you're doing a compression test.
Secondary questions: When would you want to disable either one or the other system? Let's say you want either the fuel injectors clicking or test the ignition system. What would you do to disable either (one or the other, not both) system easily?

unplug the CAS and the ecu won't do spark OR fuel, because it won't see any RPM.
unplugging the circuit opening relay (under the dash) just disables the fuel pump, but the ECU is on, sees RPM and fires the coils, which is nice if its flooded.
pulling the main fuse i think just cuts power to the ECU altogether (not sure, its more work than unplugging the circuit opening relay)
