1970 Chevelle 396 HEI Ignition No Spark

Thank you for the info RRR and LO. RRR, I didn't mean to word my question the way I did. I meant is there a fuse in the fuse box that could cause a no spark situation. If there is, which fuse could it be after looking at that picture which shows what each fuse controls. I'll find a test light and check to make sure none have blown. Shouldn't take long to test each one since there aren't too many. Thanks guys
