P0263 Fuel Problems
Well this is my first post on here, i have done alot of searching on here and tinkering to find a solution to my problem but no luck so far.
I have a 08 Dyna super glide, I deployed for seven months before which i put in fuel stabilizer, i also had a friend of mines wife starting it and letting it run every once in a while but i really dont know how often she did it. Well i came back and the bike seemed to run fine for the first couple weeks, then it began to sputter and loose power while riding. The check engine light flickered on and off, The Diag code reads out p2063 (rear fuel injector efi low) I ran sea foam and star tron through it but no luck so i changed out plugs checked for good connections to the battery they seemed fine. So i changed the rear injector and the bike ran great for a week. I goto jump on the bike last night to head to work and it starts it all over again, constant engine light same code runs like crap, i reseated the connections to the injectors rerouted rear injector connector to give it more slack. I don't have a multimeter to read out plug wires but i can prob get one, Thought i would get you guys thoughts. Oh and i live in hawaii which has terrible gas if that helps at all.
Thanks for replies in advance.

Injector low is a loss of connection, look closely at the back of the plug where it is crimped to the pins, could be partially broken there, Also pull your ecm connector and look across the pins to see if they are all the same height and one has not pulled partially out of it's socket.

Ecm looks good
I pulled ecm looks brand new like its never been messed with before, Im pretty used to looking at wiring im an electrician for helicopters, i don't see any damage on connector on either end, maybe its internal to the wiring, i hate to have to replace ecm it doesn't look like much fun.
