Swapping in an engine that has sat since 2008, all is good other than no fuel, injectors are all stuck shut. Any good ideas on how to free them up? I am going to the junkyard tomorrow to get an extra injector connector and I was going to try and cycle the injectors on the bench with carb cleaner sprayed in them. Any better ideas?


EDIT fixed them all, engine fired right up.

the dealership uses compressed nitrogen. It works pretty well. pressurize the rail with nitrogen and pulse the injector. you will hear it break free.

Thanks, I just lightly tapped them on the side while manually cycling them with a momentary switch. Had them all working in only a few minutes, didnt take much at all to get them going again.
