Good luck getting a modern diesel running in a power blackout.
EFI and electric fuel pumps galore.
Also in the US diesel is mainly restricted to heavy stuff, diesel passenger vehicles / light trucks are a fairly recent thing in the US and all of those would have ECU's so would be useless.
The only thing that has a high probability to run without something electronic are older farm tractors and heavy trucks.
Also have fun hand cranking a 22:1 CR motor
