Chrysler Repair: 97 dodge van wont start, crankshaft position sensor, distributer cap

Question
It quit one night and won't start. Full size Ram Van 2500 5.9 engine.I replaced fuel pump..replaced distributer cap..rotor...camshaft position sensor and crankshaft position sensor..spark plugs. still nothing..it only cranks..it turns over but will not start. Checked for spark and there is none from wire going into distributor cap. Plugged in computer but no codes come up. Also checked line going into carburator and it is getting fuel..Can you help?
Thanks,  

Answer
So no codes come up and you're able to talk to the controller right?Sounds like a coil to to me.I don't know what kind diagnostic tool you are using.But if you can see cam and crank with it.Then the electronic part is right.I would try a coil,may as well put a set of wires on too.Then you will be worry free for the winter.
