    so as the title states i have a 1994 6.5l with 5068 injection pump.. im finding they are hard to find for a good price so what im looking for is what it would take and part numbers if possible to swap the ecm so i can run a different pump

    If not set on switching to another configuration, give Arundel Diesel a call as the owner is 6.5 conversant; also a short drive and one day shipping distance from Thermont.

    If the goal is to ditch the electronic pump, am sure others will chime in shortly with manual pump options.

    By the way, Welcome! :)

    Is the IP for sure bad? You might not have an IP problem.

    Yes the 5068 is a one yr only pump and not common but IP's typically arent prone to failure as much as have minor electrical issues or PMD failures.

    Not trying to say you don't know what you are doing just trying to save you money. We also can't guess what diagnostic skill level people have from just a couple posts.

    Might want to check you grounds and fuel shut off too.

    Otherwise be on the lookout for any model ds4 pump than what you have and get a gm reflash or custom tune.

    Have you taken injector lines off to see if fuel is making it through to the injectors?

    no i havent taken the lines off as of yet.. it doesnt puff smoke or anything out of the exhaust.. i can pull a sensor out of the intake and put transmission fluid in and get it to fire off of that but thats all i can get out of it.. the pump has been failing for a while. kept studering and stalling.. replaced lift pump/ pmd, have pulled the fuel shut off and it apears to work as intended, tryed to pull optical sensor wire off and get it to run in back up mode off the crank sensor and no go.. at this point im fairly positive the pump is done. the original owner who was a diesel mechanic sold the truck to me telling me the pump was failing and saying he just didnt want to put the 1600 up for a new pump (it was 1600 when he looked it up at napa)
