2003 GTX 4-TEC Supercharged, 60 hours. Put in water this past weekend. Had a miss. Found two spark plugs gas soaked. Dried plugs, made no difference. Re-checked plugs, gas fouled again. Dried and re-installed. Tried to re-start, but came up with code 1656. Checked all connections and checked for open and grounded circuits both with and without lanyard attached, as directed on another site. All checked ok. In once again re-installing lanyard to try again, now have no power. Dash no longer lights up to even read a code, but the starter relay is clicking. Have looked at all fuses, and have unhooked battery for one hour with no luck. Any ideas???
