help me out here guys. I'm sort of confused as to what is going on.

*perhaps an Engine Code 31?...this is the first time I've used this so it was sort of confusing because I thought I almost caught an 11 in there...

I had that on my old motor...it was the wiring coming out of the CPS. The insulation was brittle and cracked, had to re-wire the CPS. Check the harness wiring that goes across the front top of the motor...same thing.

Thanks for the info. If its not a 31, then 13 would make some sense because i've got a couple sets of wires going across my motor that dont look too great...I'm going to go back out and check in a few to make sure its not 13...Thanks.
