What would be keeping my 1996 ford bronco 5.8 from getting fire???

What is your question?

I cant find a short or bad ground anywhere. It has a brand new (icm) ignition control module, new plugs and wires, new crank sensor, new relays, and new coil. Once in a blue moon it will fire right up. But most of the time it wont do nothing but turn over. But like i said i changed all of that out and im getting power to my coil and (icm) but still no fire! What could be causing this??
