    97.5 H1 Hummer 6.5TD need help

    That's what I thought when I did it, I felt it hit the sides and thought to myself well that is a half way decent design to stop you from jumping a tooth. Now to be fair my chain could be stretched and have jumped a tooth on the cam to crank relations but it wouldn't explain it running fine and...

    97.5 H1 Hummer 6.5TD need help

    The wiring as far as I have seen thus far is in great shape so I doubt that is the issue but I will check from the PCM connector to the component per the manual.

    97.5 H1 Hummer 6.5TD need help

    I did it again letting it crank plenty, with ckp unplugged it runs about the same. With the OS unplugged it will not start, every 4 seconds of cranking it trys to bump but that is it.

    97.5 H1 Hummer 6.5TD need help

    The diesel in the clear return line is clear and smooth not a single bubble plenty of flow/pressure that is not my issue. Aeroation is not my problem. I don't want to just throw parts at it but I have no reason to believe the PCM is bad it ran fine before, the original CKP was probably fine...

    97.5 H1 Hummer 6.5TD need help

    I did some research and I def got the pump from diesel care may of 2017, so it is past their 1 year warranty at this point. If I went to buy another one just to throw money in a dumpster fire what is the best place to get a trouble free unit?

    97.5 H1 Hummer 6.5TD need help

    What is the proper time set / TDCO procedure? I honestly don't remember exactly where I got it from but I think the place was located in TN I can do some more digging on that front see if I can find any receipts. Is it possible I have the wrong IP? The thing is though it ran ok but I...

    No there is no filter there, I moved the pump all the way back to the driver's side and it started running again but really poorly tons of white smoke. The laptop died half way through the TDCO learn before it wait running battery just died on it that might be part of the issue. I noticed the...

    This is like 10 sec of having the lift pump on, seems healthy to me. I disconnected the PCM measured the resistance across both stepper motor coils at 48ohm which is in range. Opened the PCM up looks perfect no leaking capacitors or anything burnt.

    97.5 H1 Hummer 6.5TD need help

    Yeah if I just straight unplug the PCM for 30 mins or the batteries will it reset? I did KOKO and forced it multiple times trying to get it to do something anything positive. So I could have very well confused the shit out of it. I would have thought using the tech2 is the proper procedure...

    97.5 H1 Hummer 6.5TD need help

    And yes it was throwing a P0216 because desired timing was 8 warmed up and it was running 13 actual. My actual is not following the desired one damn bit, I verified the stepper can function and that it is installed correctly. I also moved the timing adjustment lever on the IP with my finger...

    97.5 H1 Hummer 6.5TD need help

    Has a high tq gear reduction starter from Jegs forget the brand but the starter is not the issue, 2x optima yellow top fully charged. I don't see how it could not be getting a good supply of fuel but I can add a gauge in line I suppose. I'll check that, it is has the Leroy FTB kit with manual...

    97.5 H1 Hummer 6.5TD need help

    Like unplug the CPS and OS individually and see how it runs? I can't even get it to start now and no diesel is flowing in the return line with the lift pump on (do you have to crank the engine to get it to flow?).
