It consists of your injectors and wires going to them.

yes, it could be a bad injector.
if the car will run, I would suggest a load balance test to find the bad cylinder.

unplug the electrical connector and use a multimeter to check the ohms for a open or a short.

probably a rubber bushing has rotten away, letting metal hit metal making your noise. A visual inspection would be the place to start.
