I just replaced my entire motor in my volvo 760 turbo and after i had set it alland put fluids in it i started it and it iddled funny and then just died. it hasnt started since and i am wondering why. one problem for sure is that i have no spark in the coil.

I have power to the positive and negative side of the coil but no spark out of the coil. does anybody know what and why this could be happening?
Thanks
