Hello. The most common problem I have seen on this van that will cause this is an electrical short. The wiring harness that runs along the back side of the engine melts and most of the wiring ends up shorting together which will cause all of these issues. I usually check this wiring first. If the wiring is fine, then the control module may have failed.
