Okay it has been a little bit since I have posted... My D9G Still won't start and now I suspect it is the Injection Pump... Here is a video showing you the injection pump squirting... Does not have hardly any pressure... Please tell me what you think...

The fuel pumps are working A1, now reconnect your fuel lines and undo them at the injector end a couple of turns and bleed through by cranking the engine with the throttle set towards the seat or with the throttle set all the way forward into the stop position and use the hand priming pump, when fuel flows out of the loose joint tighten up as you go, then ready for the Start Up. tctractors

You're good!
I am wondering if this model has a rack limiter that waits for oil pressure to build up before allowing the engine to speed up/rack to move past idle.

I wonder if you would get better results using WD40 sprayed into the intake. You have to get a can that sprays like a paint can, not one with a straw. Might have to get inventive to swap spray nozzles etc. Other similar products may work just as well as long as they are mostly petroleum distillate.

I have used WD40 to start a couple engines that didn't want to start with starting fluid, just knock and lock up.
It seems some engines don't tolerate starting fluid much at all when there's no fuel being injected, some will tolerate it when it's just cold but fuel is being injected normally and some start/run on the stuff just fine Got a D318 that's that way and the old MACK I mentioned. Had an old 7.3 Ford/Navistar diesel that was nearly impossible to use starting fluid in. I used WD40 a time or two when it lost its prime and I couldn't get it to pick up fuel before the batteries ran down.

I would spray into the hole behind the removed filters as fast and as much as a big can of WD40 will spray while cranking the engine after using the glow plugs. If you can't find a can that sprays a fine mist don't bother, find something else, the WD40 isn't volatile enough to get the job done unless it's fogged into the intake while cranking.
D2-5J's, D6-9U's, D318 and D333 power units, 12E-99E grader, 922B & 944A wheel loaders, D330C generator set, DW20 water tanker and a bunch of Jersey cows to take care of in my spare time😄

Thats what I mentioned under the other heading about the rack limiter. Thats probably whats wrong.

The D9G doesn't have a rack limiter. If it did those pumps wouldn't be putting out like they are.

Okay the rack limiter how do you fix that. I see in the governor where limiter is but I don’t understand how that can be my problem...

I think your confusing a rack limiter with the rack stop and torque spring. Not the same thing. The usual rack limiter is an oil pressure sensing device that places a mechanical stop (plunger) into the governor control mechanism to limit throttle opening until engine oil pressure is achieved.

Okay, I still pulled the pump last night as it seems like there is zero pressure. I will send it out to the shop. The engine just doesn’t seem like it’s getting enough fuel it cranks and cranks and cranks... if it’s not IP then something is wrong with the governor. I have a long video that shows me trying to crank it and she gets close but doesn’t make it happen and that is with some ether...

Yes, on the H's, a completely different governor.

How often do the governors break on the G model? Getting a little ridiculous at this point she is being a bit of a PIA...
