First thing I would be checking is the security and connectivity of all the earth connections, the ones from engine to body, particularly at the starter motor. Also, is the starter motor actually secured firmly. 
Just initial thoughts, but the four second cranking suggests a high current draw which could easily mean a bad earth.
Of course, the starter motor itself could be bad.
