I am at my wit's end. I drove it down onto a house pad and when the back end dropped off the 1' ledge the engine immediately quit. Hasn't started since. I had to have it craned out so we could continue work on the house.
I've gone through every setting and sensor in ET and pulled a PSR (attached) and everything looks fine except low voltage on the Aux solenoid.
Removed both air filters and sprayed ether ("Engine Starting Fluid") into the throat of the air intake, and it still cranks but simply will not kick off, even with ether. Diesels are so simple that it is incomprehensible that it won't kick over for at least a few seconds on ether.
Cranking draws a heavy load on the battery so I'm pretty sure there's good compression. I've been studying the engine manuals and have almost gotten through fuel injection, but no ideas yet.
I should also mention that it had been throwing a 'fuel rail leaking' code, so I removed the fuel rail and took off the overpressure valve, and found that the seat had eroded a groove for some reason. I'd replaced the fuel rail just a year ago for the same darned thing and it was $1,400. So I had a machine shop make a special plug out of bronze so I could use course then fine valve grinding compound to wear away that groove. The seat is not polished but it doesn't seem too bad so I put it back together. A groove eroded should not happen, especially in a Cat and especially not after about 200 hours and especially not with green fuel.
Even if that valve is leaking or even if the whole fuel system doesn't work, the engine should still kick off with ether.
Any suggestions? Need this machine or else have to rent one this week.
