Verify battery is good, I just watched a hard headed friend change a starter when all he needed was a battery.. I tried not to laugh at him because it took him two days to do the starter, then had to turn around and buy a battery.. like I told him to from the start.. Check all your battery cables/connections. Clean everything if you see any corrosion build up. You possibly could have damaged your starter wire. Check or swap out the solenoid next. Also poke through your fuse boxes, you never know with todays cars.
