My Van Is not cranking We thought it was the battery but found out that the battery is good. the horn and radio and stuff works but it will not evev try to crank

Need two people to try the following: listen closely to the relay and fuse box under the hood when cranking. Listen for a clicking noise everytime you put into the start position also feel if starter relay clicking. If you hear clicking then its probably the starter. If you dont hear a click sound, sounds like the relay, burnt fuse, broken wire, etc... In that case you would have to take it to a dealership to have them diagnose it. Could be many things if the starter relay isn't clicking.

Are you getting a clicking noise at all? If not, I'd try the starter soleniod. (this is usually the problem - you can take the starter to an advanced auto and they can check it for you to be sure).

Otherwise it's the ignition (where you put your keys in). Sometimes these stop sending the 'start' signal.
