P0205 Injector circuit #5 cylinder. Started as a miss - then got worse - finally was continuous- made lots of rod/crank noise, hydrolocking the cylinder black and white smoke - Towed to dealer - They replaced injector - ran good for a week then it started all over again. I read that many injector harnesses were manufactured poorly and also the average cost of the front harness is 2 grand and thats no labor included. I did my own research on the issue. I ended up replacing the injector connector with Cummins # 3164098. Fixed the problem - you can see that the terminal was shorting out by the oxidation in the connector when I sliced it in two.
