I just done a rebuilt and street port at the same time put the motor and pluming in but the car is not gettting a spark......not the fuse or distributor.....some suggested the ecu but dont know any ideas.......

 

did you check the crank angle sensor or airflow meter? is it connected properly? As far as the ecu, if it was working fine before the rebuilt it shouldn't be your problem especially if it hasn't been removed so for now check the basics make sure all your wires are connected (and grounds, especially the one under the Intake Manifold).

Found these you might want to look at which is covering the same thing:
