Replaced starter, now car won't start. Low spark, no start.Whats the cause ? on 2001 Kia Sephia

Bought the car a month ago.Replaced starter,valve cover gasket, plugs,coils,wires, pcv,oil & filter,t-stat & gasket. Car rolled over but wouldn't start. Checked for fuel at fuel rail, had pressure and fuel @ schrader valve. I then checked for spark. My first check revealed high spark in one coil low in the other, that's when I changed both coils and the end result was low spark at both coils and still no start. What Gives ????
