My van was running fine one day when I stopped by home to eat lunch, but when I came out to start it it cranking but wouldn't turned over. The first thing I did was add gasoline to the tank, nothing happened. I had my husband listen to see if the fuel pump was coming on and he said it was. He replaced the ignition coil, still not working. He check the distributor and found it was not sparking at all. He took of the cap and cleaned it even though it wasn't that dirty. It was spinning. I am trying to decipher whether it could be the ignition control module or the distributor. The only symptoms it had prior to this was an intermittent shaking coming from the engine area. There was not a check engine light on or any stalling/ idling. Any suggestions?

You need to verify the fuel pressure. The pump may be coming on but producing little or no pressre.

As far as spark, it could be a module, which is common but you need to verify. I would remove the cap and closly inspect the distributor rotor first as it burns through if it has not been replaced at the correct interval.
