[2007BruteForce]

I'm new to the forum, and I just bought a 2006 919 with 34,000 miles. I drove it before I bought it, and it ran great. The battery needed to be recharge so I took it out of the bike to charge it and when I went to put it back in (I pulled a stupid) I connected the positive to the negative and the negative to the positive. Needless to say it blew the main 30 Amp fuse, I replaced the fuse and checked the other fuses as well they were fine. I changed the battery connections and started the bike, I let it run for about five seconds then shut it off, then I tried to start it again but it would not. It cranks over fine and the fuel pump runs when I turn the ignition on. When I crank it over for a little bit it acts like it wants to start but won't. I am thinking that it is not getting any fuel since it started and ran for a little bit before. I have checked the fuel cut off relay and the engine stop relay they function okay. I also checked the the bank angle sensor too. The bike does have a Power Cammander III, could that have something to do with it since it gets power from the battery and is not fused? I did remove the PC3 from the bike just to see if that would work, but it still won't start.
If anyone could help me out on what to look for, I would greatly appretiate it.
