Van keeps cranking but won't start! replaced coil,pcm and ignition module but still got no spark!
First thing to check is the ASD relay and voltage at the coil.
Testimonial: "Relay was the big winner here guys thanks alot!"
Chrysler products use a relay called an automatic shut down relay to power several things including the coil and PCM. You would check for battery voltage on the positive side of the coil which comes from that relay. If the coil has voltage, the next step would be to check the hall effect switch or stator in the distributor to see if it is sending a ground signal to the coil.
Relay! wow! did not know about ASD. van cranked right over, thanks again guys

SOURCE: 98 dode ram wont crank no spark
May have no spark due to a bad crank sensor, which is responsible for spark when it gets a pulse through the cars' computer.
SOURCE: 1992 dodge 318 engine turns over, but no start. No
if truck has a ceramic ballist resistor near and connected to coil this could be problem or the crk posistion sensor could be too, i would change ballast first if you have on your truck appx cost $10
SOURCE: i have a 97 dodge caravan 3.3 i have fuel
You have just about replaced everything that would cause a no start situation. Without being able to do any further testing, the only other thing that could cause that is the timing belt, check that, it could be worn, stretched out, and slipping. Good luck.
SOURCE: I have a 2000 5.2 that won't start. Changed PU
Could be one of two things. If you changed all of this and still no spark it is either a ground problem or computer is bad.
