my 2008 ford taurus x wont start up, it turns over and the battery is fine. What can it be?

Could be fuel pump,or could be a firing problem,first thing would be check for fire at a plug,if you have fire,then check the fuel rail for gas pressure,you will have to help by checking this,for we are blind mechanics,and can only go on what you say to us,but we can figure it out,we just need to know a few thing,s to get you your answer.
