Ya chances are its an injector. I have never taken one out but I know you need a special tool. You might need a trip to the Dealer. How many miles are on it exactly? The Injectors might be under warranty. Actually depending on the year of your truck it might have over the 100,000 mile warranty 
Well i did not really go in depth with this yet, the truck has had an odor of diesel under the hood since i purchased it at 99,000 miles it now has 107,000 on it, Lately the diesel smell is geting worst the area under the ecm hook ups has diesel on it like around the rail. The strange part is the is no issues on how the truck runs.
