two things I can think of would be to check the over voltage protection relay and the fuel computer. Both are behind the battery and should be covered by a plastic panel, if the panel isn't there that could explain how they got wet. If the ovpr looks ok try jiggling the fuel computer around, you may notice an instant difference.
