Van quit running and hasn't run since. The fuel pump runs, fuel pressure, checked relay checked, van will start and shut off with starting fluid into throat.

If a fuel injector shorts out it will cause the injector driver inside the ECM to shut down. I would start by checking the ECM/IGN fuse which is in the fuse panel on the left side of the dash. here is a guide to help check the injector and to see if the ECM is sending a pulse signal.

Let's run the codes as well.
