2006 town & country van won't start

You have to start with some good old fashioned troubleshooting. Is the engine turning over (cranking)? If Yes, the battery and starter are good. Does it have spark? Pull a plug wire and test. If not, you have an ignition system problem. Does it have fuel? Starting fluid is the easiest way to check (remove air filter and spray a bit in to see if it starts). Does it have timing or compression? Could be a broken timing belt.

Definitely try the starting fluid test first. Also ignition control module in the steering columns are a common Chrysler dodge issue over time they get hot and burn out.
