    I am tired of looking at the 1993 D350 sitting in the driveway. I am going to talk to a local tractor place that my former step son told me about. Probably take the whole rig there and have them diagnose, and rebuild the injector pump.

    I want to do a different fuel pin, and governor spring. I am not wanting to go whack-o crazy. This motor has 375K on it it IIRC (raining right now)

    There is seals that can handle bio-mix fuels? What do I ask for? I'm not a fan of bio-fuels as the mileage goes into the toilet for the same price as straight #2.

    Allegedly these people know these engines, and have all the tools to test the pump.

    Maybe have them "run the rack" while it's there. (adjust the valves)

    Is there any visible way to tell if the "killer dowl pin" has been corrected?

    No idea about the seals but fuel lines you will want to run Larry Bs trident hose for biofuel. KDP only way to tell if its been done is to pull the timing cover, I strongly suggest pulling the radiator and CAC first.

    240k on mine didn't have the KDP tabbed.. 20200811_230058.jpg This think was dealer serviced until I picked it up (232k) and I swear this engine dropped the dowel pin based on the mark that's in the oil pan, I really hope a mechanic was not in the case and failed to tab it.. oh well its done now

    The local tractor place wasn't interested. Referred me to another place. They guesstimated $500 labor. They were going to farm out the pump rebuild to someone in Columbia TN. Maybe I'll ship it to our member in Texas and install it myself.

    Does the truck not run? Have a proven injection pump problem? Maybe its something simpler like the lift pump, fuel solenoid, or air intrusion..

    A Bosch seal kit, and fuel pin & governor spring kit are not especially costly.

    The governor spring upgrade is IMHO more worthwhile than the fuel pin. The stock fuel pin can be rotated 90-degrees to it's most aggressive profile. Bigger injectors tend to reduce the need for an aggressive fuel pin (and setting).

    The injector pump had a small leak when I first bought it. New lift pump. Dropped the tank, it was clean.

    It would die at the stoplights. Last time it ran it was just sitting there barely idling. It would just die. It required a shot of ether to start.

    No idea where the leak was coming from. It's been a couple of years since it has run. Yes I'm aware of the grid heater ether thing. I've always disconnected it before starting.

    Not much out there on rebuilding the pump that I found. 1st Gen has a thread. All the pics are now kittens. :(

    Small pump leaks usually don't matter. You can re-prime with the manual lever on the lift pump.

    Sounds like it needs an idle screw adjustment. KSB (cold start advance) may be inop (wire fell off?) If the idle is set low, and you don't give it throttle - it will struggle to start.

    6BTs typically start easily above freezing without grids or ether.

    I think there's some troubleshooting to do before writing off the IP.

    The Bosch gasket kit is DGK121.

    Some idea how easy and cheaply you can buy parts...

    We did bleed the lines at the injectors. It was beneficial for a short while.

    First step will be getting a new battery. I put 50k on it after buying it.

    I am going to check the water in the battery today and drop my 3 amp trickle charger on it. We'll see if I can get it up to 12 volts then tomorrow toss the 60amp charger on it and make sure the motor will turn over. If it does, I'll order a battery.

    Any recommendations on battery brands?

    I have collected the funds to get this mule back to working.

    Those are Canadian parts/prices. I did a search for the parts and found this made in Italy kit https://www.amazon.com/Injection-Ga...-4786-215-8-2---1&vehicleName=1993+Dodge+D350 lots of pretty green Viton O-rings in the kit. Viton=Biofuel resistance.

    Knowing my slow moving lazy ass getting a pro to redo the pump is a better route to go.
