Okay, synced the throttle bodies today as per Jinksters write up. Put it all back together. An hour later go to go for a ride, using the choke (fast idle) it ran for 30 seconds, then died. Threw the code c41. Fuel pump/relay failure. Checked relay, it is fine....checked for continuity and that it triggers. Checked pump, fires fine....if giving the pump power and cranking the bike runs. Went to check all the vacuum. Turns out I must have disconnected the vacuum line going onto the pressure regulator on the pump. As seen in the second pic. It goes into a T fitting that shoots back to the middle vacuum line in the first pic. The other side of the T goes to the IAP sensor, which also tests as within expected voltage.
So I am stumped, I believe that since the vacuum does not exist, the pump will not prime, but I do not know how to get it to try to recreate the vacuum. I tried running it for 5 seconds with constant power to the pump.
I also tried a few other variations of the above tests. I am convinced the pump works, the relay works, and hoping that the disconnected pressure regulator caused the initial code. Any and all input is welcome, I am currently stumped.
