What kind of damage would an electromagnetic pulse do to the electrical system of a car?

First off, all solid state circuitry will be fried. This includes the engine control electronics and the stereo. Kiss your electronic ignition, electronic fuel injection, and emission controls goodbye... though the latter won't matter if no fuel ever gets to the engine. Second, depending on the strength of the pulse, anything with a coil of wire in it will generate a pulse of it's own; conductor, magnetic field, and relative motion between the two. That includes the ignition coil(s) and the electric motors; electric fuel pump, wiper motors, bulb filaments, speakers... Basically, you will wind up with an inert lump on metal and unless you have an older car with a carburetor and mechanical fuel pump and want to make a new ignition coil (any that you find on a parts shelf will likely also be fried) your car is done for.

All electronics would be fried. But it would take an unrealistically big, powerful pulse to melt coils. Older cars would still work. Since Russian military electronics use tube type technology because it's naturally hardened, I suspect that even your lights would still work.
