Could a Model T work in this world? They have a crank start and can run off 100% ethanol.
no it still needs electricity to generate a spark.
THOUGH A diesel engine does not.
A diesel engine should be able to work. Though they are hard to start. So if you had one and push started it every time then it would work. A diesel needs a lot of battery power to start (some are 24v systems) but almost none to run.
An early diesel would work fine even in an EMP.
