Engine still sounds like it has a fuel knock after injectors and still no power...
I had new injectors installed a couple months ago but truck still is performing poorly and is noisy as hell. Had the new injectors pulled and tested at Bosch certified shop and everything tested good. Had them reinstalled and had another valve adjustment done. It quieted it down some but still has some knocking going on. I have changed everything on the the fuel system except the CP3. We exchanged parts from another truck to verify the rail sensor, FCA and PRV are good. The guy checking the truck out cracked the fuel supply nut on #1 tube slightly at idle (I know, I know.. He said he knows its high pressure and he barely moved it).. The truck smoothed out and sounded great, tightened it and knock back! Same with #3. Ideas??
So my question is.. Why when he shut the injectors down on by one, did the sound not change yet when a injector line is cracked it sounds normal? He used his scan tool and then capped them to verify. Makes no sense to me..
with the miles and 2 probably failures already replace all 6 with new.
they're wear replacement items like water pumps and tires. look at them as spark plugs on HD work gas engines and what conditions they are exposed to.
Workman's comp does not pay for HPCR diesel spray into human tissue due to mechanic's screw up in any state. Self inflicted intentional act wound from dangerous unapproved unauthorized trouble shooting tech. that is specifically pointed out in training as NO

So I have less than 1000 miles on new injectors that have been tested like everyone always suggests and I need to replace them again? So what is the real determination of a bad injector? I cant get them warrantied because they passed bench testing and cylinder contribution test.
You can test all you want but they can still have probs. been there test good and still hammerd . Buy new only is your best bet the 1 s you got at cummins are remans to. You could buy 1 injector and swap 1 at a time to find culpert but time is money to just not what i would recommend.

I appreciate the feedback, I really do. Just trying to fix my truck that has driven correctly 2 days of my 7+ months of ownership. The reason I went to Cummins for injectors was that I couldn't find any "NEW" injectors with the proper spray pattern. I almost bought Exergy, but I researched on here and seems its 50/50, maybe too many opinions out there. You would think that the manufacturer of this engine would sell decent parts for it regardless, since it is their reputation. Trust me, I see people say all the time "If you want to play, you gotta pay". I subscribe but I need some play. Thanks again for the input.
