Bottom line with this is going to find a shop that is good at troubleshooting. A shop that specializes in this typically has a reputation at stake and works hard to solve it right the first time. It doesn't always go that way, but a good technican will seek to solve this as best as possible.
There are cluster problems with these and I think this is where this may be headed. There have a lot of problems with the circuit board connection to pins where the connector plugs in on the cluster. Many techs carefully resolder the connections to restore reliablity. This can also cause a "no Crank".
You can unplug the cluster and see if the van drives better. IF so, look at the cluster or replace it.
It may be a connection problem.
Connectors should be examined at the PCM (powertrain control module), BCM (Body Control Module) and Cluster.
Loopback Failure can be checked by clearing the codes with a scanner. Don't recommend pulling the battery cables off, as the voltage spike can cause damage. Turn the ignition on. Cl;ear the codes, turn off the ignition for 15 seconds, turn back on and check for codes. Loopback failure returns, look at the cluster.
