Hello and welcome to JustAnswer!
I see that you've replaced the engine but there wasn't mention of what actual problem you're having posted with the question. I'm assuming it doesn't start.
There was a change in engine control systems after the 2003 model year and a 2007 engine isn't going to run in your 2002 van as is. The cam and crank sensor tone wheels are different between the two, the powertrain control module isn't going to recognize the incorrect pattern. To make this engine run in your van you would need to use the original flexplate and cam sprocket.
