Why did you replace all of that stuff anyways? Throwing money at it blindly doesn't seem like the best way to go about it. It needs to be properly diagnosed. We don't have enough information to even get started here. When did it start, how many miles on the van, what is it used for and how often? Any mods?

Did something else happen with it that you replaced all of that stuff?

 

The only thing I didn't see you mention was heads/valve train. It's possible you have a stuck valve. You need to run a compression and/or leak down test. Is it throwing any contribution/balance codes?
