Default f4i problems please help

k so i crashed my bike last summer and have just gotten around to fixing it
(procrastinator i know:/)
so i tear into it and fix everything was messed up mostly the front end
no heres the problem
i cant get the bike to start it will turn over just fine and dandy but wont fire up
then i got it to fire up but it immediatly dies when i let go of the start button and in order to keep it running i have to keep the start button held down which then it runs fine
but now i cant get it to start anymore
sometimes the injectors squirt fuel and sometimes they dont
and sometimes i have fuel and sometimes i dont
i have the tip over senor bypassed with a paperclip in the 2 outer pins which should bypass the tip over sensor right?
everytime i turn the bike to run the back brake side relay keeps clicking unless i plug in the headlight which then it doesnt click anymore
i still cant get the fuel pump to prime but then sometimes it does prime after doing nothing
when the bike does start and run while holding the starter switch the headlights dont stay on ?
so everytime this relay in the back of the bike keeps clicking i notice my gauge cluster backlight dims and goes back to normal on every click

i can get the fuel pump to prime like normal if i jump the connector and pull it off really quick and then it will stop the clicking until i try to start the bike and it starts clicking again
i can also leave the jumper in that relay and have the fuel pump just keep priming while im trying to start the bike but the injectors wont squirt

someone please help im stumped on ideas
anyone know whats going on here? i really really need this bike to work and all help will be greatly appreciated

by starter box you mean you're jumping the battery to run it?

the bike needs a certain voltage at the ignition coils so this might explain your problem if you are not using a properly charged battery..

Have you rechecked the Bank angle sensor ? It is Behind the Clocks little black box about 1" by 2" square with black resin.

It should have 3 wires connected, cant rember which ones you short out if its not working, think there is a thread explaing how to by pass it

some one jump in please.
