engine computer is located under the hood, typically on top of the passengers side fender well.
I suspect you toasted the alterator, take it in to an autoparts store and have it tested for free.
While your there, have them test the ICM too. It controls spark timing to engine timing.
After that, its a chase the electrical around the engine. Distributor, wires, plugs, codes, cables, etc.
FYI, you can use a battery to weld two pieces of steel together in an emergency, it'll toast wires and sensative electrical components in half a heartbeat.
