New to me TC29D cranks & won’t start

[CalienteJohn]

So I’m finally back life happens and I had to learn to rebuild our Polaris ranger front diff and axles. It services our small ranch and took priority.

To the tractor my thought was to test my gauge to known good diesel (only one we have is a kubota bx1800) got it disassembled to learn my deluxe tester kit doesn’t have the correct adapter for it… lovely

So tried to rent one. Only gas ones available anywhere I checked oriley autozone etc etc

So I went ahead and purchased a second one with the intent of keeping if necessary and returning for other tools if not.

Tested compression side by side gauges measured within 5 lbs pressure of one another…

No surprise. Shops would go out of business if they had to double purchase every test instrument.

To screening & checking engine oil

bought paint screens and cut apart old filter with pipe cutter
Oil and filter were very dirty but nothing out of ordinary in catch pan oil filter or paint screen… found a few chunks of orange paint type material in screen was the most significant…

Agreed but it was mentioned multiple times so I thought worth a try

The low compression, blow by and the sound of the way it cranks would be enough for me. After all the years working on engines I can tell low compression by the sound of the way it cranks.

INJECTION PUMP. PLUNGERS ARE STICKING INSIDE THE INJECTION PUMP.

Remedy?
Have pump Rebuild at a shop or diy?

IMO we might could have sorted this out by now while OP is doing everything right so far. I also suggest that further tests of fuel delivery may bear out before shotgunning a new pump/parts and bucks if not needed.

btw, I'll be here 'til we get our guy up and running. Ask me later why I'm so fired up to do so.
