Multiple problems? No spark, no injector pulse AND no fuel pressure?

No spark, no injector pulse could be pickup coil, module, wire harness to ECM, or a faulty ECM.

No fuel pressure even with the pump running could be a failed pump, a broken rubber hose between pump and hanger, or a severely plugged fuel filter. Less-likely to be a failed-open pressure regulator, but possible.

Thanks for all the input. New parts in and running fine. I found the problem and I knew it would wind up being a simple mistake on my part. The wiring plugs on the coil were broken and the one from the ignition was the worst. I bought replacement pigtails but I had only fixed the one to the distributor because I could take it completely off and solder it in my workshop and do the other later. I managed to plug the other in backwards when I changed the coil. I found it because I suspected the new coil being bad as it was running with the old one. I got the old coil and hooked it up, that"s when I saw my mistake. Live and learn, sometimes the hard way.:(
