Yes, I just went to Napa auto parts and bout a heavy 4awg cable
instead of the 6awg cable that I had (another one already was 4
awg). It helped in the sense that the diesel did actually run a few
revolutions.
That spark plug-looking thing in the intake manifold is the preheater.
It probably heats a ceramic disc with nichrome strip as a heating
element. It may work a LOT better in getting the engine to start
and keep running than trying to heat the manifold from the outside.
Putting the exhaust of a propane torch in the intake will give it
hot air, which sounds good, but there won't be much oxygen left
in that air. But, if it fires at all, you'd expect black smoke.

If all else fails, you might need to heat the cylinders a bit.
If you heat them to the point that a drop of oil smokes, then
you definitely should be able to get it to run. If it still doesn't
keep running, there may be crud in the injection pump or injectors.
(Somebody else said this model was self bleeding.) So, you may have
to just run it through, or loosen the fittings at the injectors
and let the pump purge the old fuel and debris.
