Default 4.6 weak start?

Hello- my 1997 4.6 is starting hard or very weak starts. I replaced the starter,also a new battery and now today a new alternator. Now is not starting at all unless I jump it. Could it be a bad starter or did I wire the starter wrong? Donít think that would be the problem cuz the starter is only about 2 months old and no problems till recently.Also when cranking when weak I see it throw a spark near the starter? Possible short ? Any suggestions? Thanks
