    Would a weak cylinder that may consume oil plug an injector with carbon?

    All of that damage can still happen stock. Dirty fuel or fowled injectors will discuss it. Let me fire up the old computer and pull the manual off it and I'll email it to you...

    Thank you so much. Another question but I think I know the answer so after I did the bandaid I put a new injector in #1 after about 1500 miles I had to replace #1 again. And my dumb luck it seems it's time for another injector but I haven't looked at it yet I gonna take a shot in the dark and say it's #1 again. Could low compression damage a injector or ( my stupid luck ) does it need a transfer tube except the original transfer tube is in the trash so that couldn't be it or because factory lift pump and filter are still messing things up. Getting ready to buy a FASS just haven't ordered it yet


    And thank you for helping me out with the Manuel I'm sure it will be a huge help

    The manual is a huge help and education into the systems on the cummins.
    I'm not 100% sure on a poor cylinder would burn up an injector. It would give poor combustion and should puke out black smoke. You may have an issue with the injector harness may have a nick in the wire poor connection somewhere causin the solenoid to fail. There is a test with a ohm meter to detect if all are working right and it's a ecm issue.

    I pulled my hair out with injector issues before I figured out the issue. Went through 2 harnesses and 2 sets of injectors and 3 extra. Turned out it was the fowled fuel system causing the injectors to fail. Probably not the same issue your having but sounds similar

    Once I get in from working in the shop, I'll look for the manual and send it over

    I thought maybe fuel system as well buying a Fass 150 titanium today and getting new fuel transfer tubes might as well get the fuel system taken care of and new injectors before I rebuild the motor.
