Problem with 3, 5 and 8 injectors

Hello,
just got off the phone with the shop as they ran diagnostics on the my truck. They told me injectors 3, 5 & 8 were bad. They suggested replacing all injectors and quoted me at $2800.

I'm going to do it myself, but was wondering if replacing all was really necessary or could I just replace the ones that are bad?

Any help would be appreciated. I haven't been in to talk to him yet so I will update with more info when I get it.

Did you ask them why they were "bad"?

In short you can just replace the ones that they claim are bad. People do it all the time.

no we just spoke briefly as I don't have good phone reception where I'm at. I will talk with him in person when I go in and update.

Thanks for the reply. I'm still trying to learn this diesel thing so wasn't sure if it was advisable to just replace the bad ones vs all.

Id base it solely on whether or not you've got the cash to replace them all. If you do, personally I'd do it just to get them out of the way - I'd save the old ones that are still good though, just in case.

If not, you'll be fine replacing the problem ones too. I've always just wanted to get everything out of the way if I was that far into something.

If they were all on one bank I would lean more toward a bad uvch but with no. 8 thrown in there who knows. Maybe both harnesses went at the same time???

Re: Problem with 3, 5 and 8 injectors

Sure it's not a CPS making them"fail"

I made my Samsung SGH-I997 send this.

He said 3 & 8 were dead and 5 isnt contributing like it should. Ive been having an injrctor problem for around 8 mnths or so if that makes any difference.

Thanks for all the input.

Ok? So? I offered advice. Change the CPS. #3 and #8 are common CPS caused codes. #5, not necessarily, but I'd try it along with checking the UVCH to each injector.

I appriciate the advive. Im pulling no codes. If the cps is bad wouldnt that cause a code? The reason i took the truck in is because of a major miss/shudder when driving. Its like driiving a paint shaker. I will loook into cps as ive already checked the harness awhile back.
