1999 GMC Savana

Computer problem
1999 GMC Savana V8 Two Wheel Drive Automatic 220000 miles

Going through a deep padle of water the engine stalled within 2 seconds. Tried to start for one hour and suceeded once for 15 seconds. Towed the van home put a fan to dry the vehicle, recharged the battery, but when tried to start the engine turns but wont start. I sprayed silicon on the computer wiring entering the box checked spark plugs they look dry. Wandering if computer wiring is removed from computer will the computer need re-programming? Also can something short out & stop working if it gets wet? Full pump works, gas is in the tank, wiring & rotor were replaced recently. Thank you
