i have no spark on 1994 Ford Escort

i had the timing nelt slip or wore out , so i changed it , made sure number one was tdc , and the cam was were it had to be with the marks , and started and no spark , so i changed the cam sensor , and still no spark , but i just hooked it did not ground it were the 2 bolts go to just wanted to see if it would start , does that make a difference if it was not grounded?

Grounding everything is very important, Did you remove the top of cam sensor with the 2 screws, or the whole shaft then replaced it.
