Auto starting for low batteries, is there such a thing?

Maybe a hood safety switch, you probably have one already for the stock alarm? An audible alarm, beeps for 10 seconds before starting? As for kicking on a 3am, when we go hunting there are loud generators, louder than a diesel, running all hours to keep campers warm.

And my truck will simply shut down in a low oil pressure situation.

Well, technically all engines have this feature. :Wow1:

Yeah... But the HEUI injected 7.3 and 6.0 Powerstrokes happen to shut down before they blow up. If the oil pump starts to suck air, it'll lose oil pressure to the injector drive setup (the injectors are fired with oil pressure), so the engine just stalls.

Personally, if I were to rig anything like this, it would need to have both low oil pressure and high coolant temp shutdowns. And if one trips, don't try to start again until the system is reset.
