New parts more often than not equal junk. Firing the parts cannon is a good way to create a bunch of problems. Does your fuel pump come on for a few seconds at key on? Is there fuel on the plugs? Are you checking for spark at the coil wire or at a spark plug? It's always best to have a scanner of some kind to see if the PCM is powering up and seeing the crank sensor signal. I'm not certain on a 97 black box if no cam sensor will stop it from starting. I know later models start in batch using just the crank sensor, then switch to sequential once the cam sensor is steady, but there isn't much info out there on the 96/97 black box. I know distributor gears are very failure probe on these and can cause all kinds of issues. Crank sensors are normally pretty good. I can count on one hand how many ignition modules I've seen fail on these(most of those were aftermarket ones installed chasing problems). Another thing to do is the wiggle test. I've seen many of these trucks where the wires break inside the insulation right near the crimp. When ypu wiggle it, it will move very easily or have a small spot where the insulation has shrunk down around the broken wire.
