Hey all, i am replacing injectors on an lbz.. #7 is stuck and will mot move.. I have tried just about everything.. I also used the snap on injector tool and it pretty much laughed at the tool... I tried the pry bar and 2 pry bars.. I tried an air chisel to see if the vibration would help.. At this point the hold down is pretty much trashed... I would try a slide hammer, but the a\c is in the way.. I tried soaking it with blaster and that didnt do much... I used some carb cleaner and it moved a little after that.. I have been working on it at least 10 hours.. I have replaced a lot of injectors in trucks and this is the first i have ever seen that is this much if a pain.. Any ideas would be greatly appreciated...
