You don't have to do it that way but you'll have lots of fuel spraying all over the place if you don't. The 2.4 turbo engine has higher fuel pressure ratings than most cars so the fuel will spray further and longer. It is quite easy to pull the fuel pump relay and turn it over... runs for like 2 seconds.

If you decided to just bypass the depressurization step, make sure you have a cool engine, no electrical components around to spark and have a fire extinguisher handy.
