I sure hope you guys can help me. This morning my wife's '02 Expedition w/5.4 & 60k miles would start and idle but would die after about 10 seconds or if you pressed the accelerator. Did a few searches on some Ford truck forums and it sounded like the Idle Air Control Valve so I replaced it which, as is usually my luck, it was not the problem. Did some more searching have and checked the following.

Can't hear a fuel pump but I'm used to the unit on my F250 diesel which is loud
Both Fuel Pump fuses OK
Fuel pump relay OK
Fuel filter probably has never been changed and I'm thinking about doing that. Before the filter goes back on though I'd turn the key on to see if any fuel comes out the line
Fuel pump inertia switch not tripped but I have not checked for power at the pump either.
No pressurized fuel out of the fuel rail schrader valve.

Now it will not even idle. Have I overlooked something? How do you test the pump? I may be forced to have it towed to a dealer since it looks like its the fuel pump which is located in the tank. I could do it but really don't feel like it but it would save me $800. That's a set of tires and one entry fee.
