Power to coils, no spark?

I'm almost finished swapping an LS1 into my 86 Iroc. My current problem is I have no spark. I'm sure it's something small, but I'd appreciate some help. I have power to the coils, and fuel rails, along with the other necessary parts. A sensor maybe? I'm not sure.

Re: Power to coils, no spark?

Assuming the wiring is OK, the main sensor that controls the INJs and coils is the crank position sensor
