Electromagnetic Pulse will only destroy microcircuits, and only if they're running at the time. So the engine computer in your car will be fried if you're driving, but not if the engine is off.

Simple generators should be safe even if they're running, but if they have circuits to control power, rpm, frequency or the like that's going to be more sensitive. In other words, the more expensive the generator the less Godzilla-Proof it is. Cheap generators don't have any controls of anything, or just mechanical controls, maybe just a set of big rectifier diodes for a DC jack.

{edit to add**

The basic idea is that the EMP will overload conductors. The smaller the conductor or the closer to it's limits it runs the more sensitive it is. Transistors are tiny, so they're easy to fry. Copper wire, not so much. An interesting historical factoid, during the Cold War the US had B-52 bombers in the air 24/7 "just in case." Those planes were one of the last uses of tube ("valve" in UK?) circuits for radios and avionics, as a nuke-hard redundant system.
