Doesn't an EMP only fry the electrical systems of things that are actually running at the time?

In other words if a car was on when hit by an EMP it'd be trashed but if it wasn't running no damage.

No, I understand that it induces currents in any conductor, which are at high enough levels that they tend to fry sensitive components.

Then again, if you keep your car in a metal box that shields against the pulse, you may be OK.

EMP destroys chips whether they are working or not. The EM pulse is of a wavelength that the wires in the chip will pick up like an antenna. These wires often lead to transistor gates, which can be blown out by sudden large voltages. (Transistor gates are very delicate things - comprised of only a few atoms thick layer of SiO2.)

I know a bit more about this on both the risks and defenses, but I'll just shut up due to the nature of the issue...
