Fuel injection systems do not need to "bled." However, if Questioner is actually trying to ask, "Should I relieve pressure in a fuel injection system before performing fuel system maintenance?" then the anwer is yes.

You run out of gas and get air bubbles in your fuel system, which may be a problem if it doesn't self bleed, although most modern fuel injection systems do
You can prevent fuel injection flooding by not pumping the gas pedal when trying to start the engine. Fuel injection systems do not need any additional fuel when starting the engine.
Carburetor and injection.

The computer controlled fuel injection/air intake systems. So a computer chip takes the place of a choke.
That is normal for fuel injection systems.
more susceptible to icing.

There are many types of fuel injection technology, but there are four very popular systems made available for newer cars. They are single-port, multi-port, sequential injection, and direct injection.
Is it normal to bleed a lot if you leave the two month injection
The 1991 Nissan 320 Turbo does not have a choke. The engine has electronic fuel injection. There is not a need for a choke with electronic fuel injection systems.
