F4i Won't Start
got cbr F4i for free from some yahoo who I did some work on his RR900 for him. The cbr doesn't run and I downloaded a manual for. It won't start tho if I give it either and try to start it for a minute it will actually catch and fire off. I turn on the key and the f1 light gives me 15flashes which means there is a problem with injector number 4. I have followed the manual and done all the testing and everythign seems to check out. I'm not real sure what I am doing wrong on this and am hoping someone can give me some tips.

But even on 3 cylinders with #4 not working, should still kick over easy. Also is the Fuel pump kicking on for about 5 seconds when you turn the bike on? could be poor fuel pressure which would explain why it isnt kicking over well.

So it turns out the ground wire for the injector was broken from the molle connector at the lil brain box. I rewired it and put in a new connector and it starts right up now. It sounds good too, these thins wind up like lil watches.
Now I have a new problem, the guy before me apparently decided to pull out the fuel pump and when he put it back on he broke one of the bolts that holds it down. Obviously torque specs were not their concern. My problem is can this be fixed or does this require a new tank?

Post a pic, May have a cheap and easy fix for you, I Have an extra set of throttle bocies and they have the injector subharness still pluged in. If thats whats bad i maybe able to sell you the subharness if the mods dont mind, and you live in the us (you pay shipping for small flat rate box)

I do have a broken bolt on the fuel pump tho and it's spewing gas. I don't know if that bolt can be fixed or if I need to replace the tank. Do you have any idea on that one?
