Well the coil wire is......... on the coil. The coil is on the driver side head and the wire is only like 8 inches long and goes down behind the water pump. BUT, if the driver side plug you pulled sparked, then the coil works. Pull one on the pass side and check it. I have heard of single banks going down before but I can't remember why???? There was a guy on here I remember having this problem but it seems like his was just loose wires............ Oh well, I can't really recall if this is possible but it won't hurt to pull a wire on the other side to see.

probbly just needs to dry out. might try to hook a vaccum up to the vent tube on the opti to help dry it quicker. if you can i would pull a spark plug or two to see if they are fouled out.

are you giving it gas as it is cranking because if you are, it might be flooded. but it still sound like you got moisture in the opti. you have a non-vented opti so it will take time to dry.
