ICM = Ignition Control Module (for anyone just starting out)
I'd also make sure you have some heat sink compound to go with the ICM. Computer CPU heat sink compound will work.
Fuse kit was already mentioned too.
Ignition coil, Cap and rotor is also a good idea.
Penetrating oil. PB Blaster or Liquid Wrench are good penetrating oils.
Tire repair kit. (much better than having to use your temp spare that may have dry rotted over the years and you're 200 miles from home). Still have the temp spare just in case, but I'd try to plug the tire if possible.
Basic tool kit.
Cell phone charger
Credit card for emergency repairs (meaning don't plan on maxing out your card on vacation and not have credit available should you break down)
AAA membership isn't a bad idea either.
The fuel pump relay is nice, but not required. There are two on the car.
Either the oil pressure relay or fuel pump relay can turn on the pump. If the fuel pump relay dies, you have to crank the engine long enough for oil pressure to build, then the pump will turn on. However that assumes both are good and you haven't been driving with 1 dead relay for a while. Check them both and if they're both good, that's your spare relay.
