JUST RELEASE THE PRESSURE AT THE FUEL PRESSURE TEST PORT ON THE FUEL SUPPLY RAIL THAT SUPPLIES THE INJECTORS, IT IS A METAL VALVE LIKE A TIRE VALVE, THAT IS THE FACTORY RECOMMENDED METHOD..

are there any fault codes present? i was looking at the fuel injection diagram on autozone.com and the only thing i can see that controls injector pulse width is the pcm. are all the injectors open for 15ms? you should also check fuel pressure. if you want to look at the diagram, go to autozone.com. register and enter you car. select repair guides, chassis electrical and the wiring diagrams

SOURCE: need to know location of fuel pump relay

The pump is in the tank. Before you consider dropping the tank. Lift the carpet in the back seat above the tank. The older MPVs had a trap door which would access the pump with out dropping the tank. It is definitely worth a look. I changed mine in half an hour.
