My 2003 Expedition won't start. Replaced fuse panel which has a new fuel pump relay. What should I check next? Fuel filter or pump. It has 265,000 miles.

Do you hear the fuel pump prime when you turn on the key?

I dont think so. But I am hard of hearing. It does run if fed fuel thru air intake.

Did you check the fuses? If you have a multimeter you can check for power at the pump. If you have power to the pump you probably need a new fuel pump.

I dont think so. But I am hard of hearing. It does run if fed fuel thru air intake. This same issue occurred about 3 years a go and the I replaced the panel due to failed fuel pump relay. I checked fuses and none blown. SO I put a new panel in still does not start unless I put fuel in the air intake. I do have a volt meter. Wher is the plug for the pump located ? Near the tank.
