The antidote is called a Faraday cage. All good preppers keep sensitive electronics in it. And keeping a spare computer and ignition box for your F150 in there is a great idea as well.

Or keep an old fashioned vehicle around with points/condenser ignition...

I believe even the plastic airliners (Boeing’s Dreamliner) have a Faraday cage designed into the structure — not specifically for protection from EMP used as a weapon, but for protection from lightning.

So do you shunt or open the spare module for your engine, so the spare doesn’t get fried at the same time?

Some have suggested a defunct microwave oven as a good option for safe parts storage. I'd pull the old electrical components out and ground the case, but that's just me. (You might just find that there's a bad cap on the board and get it back up for a buck or two.)

As for vehicles, pre mid-'80s without computer controlled fuel injection. Spare loaded distributor, plugs, wires, coil, starter, alternator, and battery. Toss in a spool of wire and a box of connectors. Takes a lot of old microwaves to store all that stuff. :)

It's all in here.
