Busa problems


Been having issues with fuel pump coming in and then not coming on. Sometimes I can take off for a ride and F1 light comes on and bike dies but will start back up right after. Other times it cuts off and fuel pump won't even cut on for a few hours. Did jumper to see if I could get codes but no luck even tried to you tester light to see if fuel pump was ok didn't get any light at all but it would start right up. Tried it when fuel pump didn't come on still nuthing! Tested side stand, fuses, kill switch, tip over. Don't know what else. I missed..... Ready to get this bike back to the track and help would greatly be appreciated
Found the problem by the fuse box had a wire harness clamp was broken. It Would shake apart if moved
