I recently sold my 770 and with that went my repair manual, it covered the 1070 as well.
Unless we start from the begining and check the major components it's just hit or miss, and without my repair manual I'm hesitant to suggest the next step. If you've checked the fuses and relays, and made sure everything is getting power, perhaps the thing to do is
buy a repair manual, although maybe someone here may be able to guide you through the steps.
Diagnosis is an underappreciated part of mechanical repair, it takes an understanding of how the machine works and where to check for power, ground, signal, pressure, timing etc, and why..
1: engine cranks..battery is most likely good enough to start engine
2: fuel is getting to injectors, is fuel getting into cylinders?
3: are injectors getting signal, or enough pressure to open? most likely not, but you need to check.
If I remember right the 1070 has a direct injection engine, with no computer (I could be wrong). That would mean injectors are pressure operated by the injector pump timing. (if this is wrong, please correct me)
Luckily I never had to do more than minor service to my 770, I did replace the alternator bearings, but that's it.
I've worked on gas auto engines for the last 30 years, but I'm not a diesel tech, however
there is some talent here, hopefully one will join in with the next logical step.....
MICHAELL, hope something simple has happened, but not familar with the 1070 enough to guess what.
