Changed a fuel injector, now cranks a lot before starting. on 2004 Nissan Xterra

Vehicle used to start immediately. When warm but off for 20 mins or so, would start right up but idle rough as if on 5 cylinders, this would go away after a few minutes. Then finally CEL w/code P0303. I replaced #3 F.I., now initial problem is gone, however now has new symptoms: 1) Excessive cranking before it finally starts 2) Runs rough upon start-up for about 30 seconds (hot or cold), but runs fine after that. 3) Recent CEL w/codes P0303 & P0328 (new entries - I had reset the computed after the FI change). Question: When changing a fuel injector, should the fuel lines be bled somehow? If not, any ideas for me? Thanks!
