Anything is possible, but probably a long shot. Injectors are pretty simple devices and they are not hard to clean and test. I would hope that if an injector was damaged during testing that the tech would have said so.

Anything is possible, but the injector wires aren't really long enough to erroneously connect an injector wire/connector to an adjacent injector. When I did my injectors over Christmas, I just let the wires/connectors hang loose and it was incredibly obvious which injector wire went with each injector. I mean, its not like an old V-8 ignition distributor where you have 8 wires and 8 holes and have no idea which goes where or where its easy to get them mixed up. Someone would have to seriously pull on the wiring to get this to happen.

Yes, if a pair of injector wires were indeed swapped between two adjacent injectors, then they would be spraying fuel at the wrong time. The engine would probably run like it was badly mis-timed.

All the same. After cleaning and calibration, any injector can go into any cylinder.

Did the non-working injector work when he swapped the two injectors? If not, then that injector failed to work in two cylinders and is probably failed. If so, then there is something else going on.
A competent mechanic should be able to figure this out pretty quickly.
