So my 1968 GMC 1500 had the old distributor set up, so I go and do the HEI like I have in countless other cars and trucks I have, I run the HEI from the fuse panel and have power to the coil, but can't seem to get any spark, I rebuilt the distributor with all new parts thinking that was the issue and still nothing, could this be a grounding issue? I'm Stumped and about to just reinstall my old set up with a petronix conversion, and yes I ran a jumper from the battery to also see if that was missed power issue and nothing, any ideas? Thanks!
