I have a 1985 Chevy S10 Blazer, 2.8L V8, and have been having issues getting it to start for a few weeks now.

I've changed all the spark plugs, the ignition coil, the distributor cap, rotor, and ignition module, but it seems I'm still not getting a spark and can't get it to crank up. It turns over as if it is trying to, but just won't start. I've tried adjusting the timing, and I've tried multiple firing orders that I've found online. Wiring around the control module is a little beat up, but still connected. It is getting fuel as far as I can tell. I'm running out of ideas, please help I've gotta get this sucker running.
