GMC Repair: How do I get my truck to fire?, crankshaft position sensor, wiring schematics

Question
I have a 1995 gmc half ton pickup with a 350 engine. It is not firing. I replaced distributor cap, rotor, module, coil, plugs, plug wires.  That did not fix the problem.What do I need to check now?

Answer
You need to see if you are getting power to your ignition module. Also I would check your crankshaft position sensor, and the PCM to see if you are getting signal from your sensor to the PCM. I do not have access to 1995 wiring schematics at this time or I would give you more detailed instructions.
