Washed the entire engine and wet the computer box and shut off before i even finished!

Yeesh. All you can do now is pop the cover off the ecu and dry it out, give it several hours to thoroughly dry. Then check all fuses/relays/fusible links and battery for proper voltage and try to start it. In the future, don't hose down a running engine. Just leave 'em nice and greasy.

Never wash an engine. Unless you are going to wipe away until it is done. Power washing or spraying an engine is asking for issues. With today's electrical sensors and computers.....
