Wow, 6 codes, the last 4 could be because of you messing w/ the injectors. The first 2 which are the TP sensor and IAT sensor shouldn't keep the bike from running.

This part of your original post is interesting

can you get the bike running now by doing this? If so then the issue is w/ one of the lines or one of the parts they are connected to.

if you took apart connectors then you will get those codes. i think ,12,13,14,15 are injector codes or #'s near them, check book. if i am not mistaken you have a fuel return line that returns fuel to tank. like if you jump fuel relay pump will just constantly run, delivering fuel in a loop back to the tank. have you checked the fuel filter in the tank, the metal one not the brillo pad one? also when you turn the key on and the stop switch on (red) fuel pump should prime for 1-2 seconds and then stop. does that happen? or does it just keep running?

ok sorry to sound rude but if im getting too much fuel through the injectors i would think the fuel filter would have to be good and yes i know al about the fuel return and the fuel makes it back to the tank lol.

how much fuel pressure is there? did you actually check it? maybe too much fuel pressure is not the problem at all.

ok i can see the injectors spraying. i pulled a cop and tested the spart and its good.so i pulled the valve cover and checked the timing and its right on. its not throwing anymore codes. i know its got good compression. i tripple checked all the sensor connections and tested all the sensors and everything is all good. when it does try to start i let off the start and it stops with the starter. all i know is i am running out of ideas. is what i feel like right now. ever since i fixed the in tank fuel leak it started going down hill and fast.
