I think BOTH of the quiz questions are wrong an EMP can cripple a car but not permanently, stuff like relays could fuse shut as a DC current is generated, fuses, bulbs, relays could pack up. But the hard part is vehicles with electronic security systems that could be shorted or damaged or the system thinks its being tampered with and dumps its memory. unfortunately many vehicles not only have security coded chips in the IGNITION system but also often in the FUEL system. My old Ford Van was a diesel with coded keys, when someone tried to steal it the codes that allowed it to work were dumped by the Ignition controls and the fuel lift pump.
Some research by the UK military suggested batteries could be killed and stuff like starter motors become demagnetised or something if enough energy is passed through them.
Some AMERICAN preppers have deliberately bought or BACK dated their vehicles with stuff like MECHANICAL fuel lift pumps, AIR starters and remounted or retrofitted cranking handle lugs on the crank shafts. Some I know keep spare ignition modules, fuses, relays etc in tin boxes as spares incase of EMP.
