Answer
First look over your work and make sure no sensors are unplugged.  The crank sensor is located on the back of the block.  I am assuming the car is cranking.  If it is not then you need to check for power on the purple wire going to the starter when in the crank position.  If it is cranking you need to check if yiou have spark.  If it has spark more than likely you have a fuel pump issue.  I suggest towing it to a dealer and have them perform diagnostics on the vehicle.  That will tell you what is wrong.  Good luck.
