Ok first your van doesn't have a carburetor. It's fuel injected. If you're priming it by pumping the gas pedal you're flooding it with gas. It could be a coil pack, fuel pressure regulator bad plugs and wires the list goes on and on.

Have you checked to see if you have spark on all your coil packs?If so are they all the same color spark? Find a spot in the induction hose, and spray a couple shots of starting fluid inside, put the connector back into induction hose. See if it starts. If it does, you have a fuel problem. If it does not, then look else where's in the engine. Could be a crank sensor just starting to go bad.
