Well I got the Cat yesterday afternoon and pulled all the access panels off to have work space around the motor. I tried to start it and only got a hiccup so I decided the easiest thing was to start at the spark plugs. The front cylinders plug appeared normal but wet with maybe a little bit of rust discoloration on it. The rear cylinders plug was wet but was "beaded wet" and had rust deposits in the plug. Not alot but can definately tell that water was on the plug since it was "beaded up" and has been in contact with it at some point. I will also say that the mechanic had replaced the spark plugs when he had it.
The fuel pump is cycling when key is turned on. I cranked it over with spark plugs removed and it is throwing fuel from the cylinders (out the spark plug holes) on every stroke.
Based from my initial observation.....the rust corrosion on the spark plug is a big concern of mine but maybe it shouldn't be. In my opinion there should not be anyway for rust to take place unless water is present inside the cylinder. Since the problem not starting came on fast and has full tank of fuel.....it wont start, fuel pump appears to be delivering and rust on the plug makes me think that there is alot of water in the fuel. It makes since based on what I've seen so far. My father in law said he filled up the tank and after that it started not running as well. Then it sat and next time he wanted to use it...it started and then died. Makes me think the water settled in the tank and the fuel pump picked up the water.
Later this afternoon I hope to buy a new set of plugs from the parts store and verify fire on both cylinders. I also hope to get the fuel tank out or siphon out all the fuel (and possibly water) thats been in the tank for roughly a year. I may not need to do this but I'm starting simple with new fuel and spark.
