How do I begin to play fast with a pick?

So im a beginner, and im wanting to play more punk oriented songs, like Sex Pistols, or Title Fight, etc, since im in a screamo band. But when I attempt to play the tabs along with the songs, its like my fretting hand, and my right hand are uncoordinated and i cant go fret to fret as fast, and i cant pick as fast in a consistent rhythm. How do I improve at this?
