There is a very simple way to address both concerns on a 2.1. Your
question overlooks one thing though. The fuel system retains pressure
for a very long time after the fuel pump is off. The injectors will
still spray a lot of fuel with just the pump disabled. This is how I do
it. On the front edge of the block box above the coil is a 2 pin
connector with 1 red wire on one of the pins. Unplug this from the side
of the black box. This disables the fuel pump, fuel injectors, and
ignition system. (as well as ECU, ICU)
