That is true, but you always want to diagnose things that require the least work and are cheapest.
I mean I picked up a set of injectors because I "thought" mine were bad for the sludge monster. $50 later it's still the same, then I went turbo and couldn't even use them.
Plus it takes a minute to switch out the connecting clips, while it will take 30-1hr to remove the rail and injector, then get new O-Rings, etc. etc.
