It takes just a tiny amount of leaked fuel to bleed the pressure off in the system, then any leaking will stop. Rather than running the engine to look for a leak, it's more convenient to bypass the fuel pump relay. I can't remember if your van has a separate relay. If not, bypass the automatic shutdown (ASD) relay, terminals 30 and 87.
