No fuel presssure
All Fuel Pumps are inside the fuel tank
Have to drop the tank down & remove pump
from the top
Been that way for 25 years
First you have to diagnose the real problem
Can't assume the pump is bad
Yes , no pressure at schrader valve, replaced the simplist,,the fuel filter can't hear the the pump pressurize when I turn on ignition
Why would you replace a fuel filter? That is something you do every 3 or 4 years,so you know about that. You should have a wiring diagram,then you could try jumping the relay for the pump. You may have a grounding issue by the tank from dirt & rust. Most likely have to drop the tank to check out the pump

On your 2000 Mercury Grand Marquis 4.6L SFI , the Fuel Filter is located: Under vehicle, passenger side, below seating area, passenger side of fuel tank, mounted on frame in fuel line
it is attached to the frame near the rear passenger side door by a hose clamp, so you need a screwdriver to loosen the clamp, and pliers to remove the lines.
Mercury Marquis Fuel Pump IS A 94, BUT IT IS THE SAME FOR BOTH YEARS.
