I have this explorer, stopped running, took it to the repair garage, they said it was a fuel pump. I replaced the pump, filter. Truck started, ran for 10-15 mins then shut down. I checked for fuel pressure, none. Yes there is gas in the tank:} anyway.I am getting voltage to the fuel pump relays, and to the inertia switch. I will check voltage at the pump harness. If ok, I will jump in 12 v to the pump and see if the pump is working. Assuming it is. What will be my next step?

Sounds like a good idea-when you jump the pump and it doesn't produce the pressure as required inspect it-lines okay on it-get rid of it

Hello: First of all this is not my truck, It is my sons girlfriend. And your reply is not what I need right now. Getting rid of the truck is not an acceptable answer, sorry. Please respond with a next point of attack to get the problem resolved.

When I say get rid of it I meant the fuel pump-not the truck.

When you apply battery voltage to the fuel pump and it doesn't come on-check the ground if okay replace the pump. If it comes on and still no pressure-inspect the fuel lines to the fuel pump and pick-up tube inside might not be pulling fuel

So, what you are saying is, if the pump comes on then I still might have a problem with the pump system in the tank. Ruling out a kinked line going to the filter. Now that I think about it a kink in the line (the braided end next to the tank) from the tank to the filter sounds like it could be the whole problem that would explain no fuel and no pressure. But what I am after is, say the pump fires up and the truck starts, proving nothing wrong with the pump or the lines. And I dont have the voltage at the connector for the pump?Does the voltage for the pump come directly from the inertia switch?

The power comes from the fuel pump relay when the computer energizes it -then to the inertia switch then to the pump

Being that I have a constant 12 v terminal at the relay in the fuse block can`t I just jump from the hot terminal to the leg going to the inertia switch therfore bypassing the relay to test for power at the pump

You can do that and also it verifys that the wire is good all the way to the pump instead of using direct battery to the pump

Do you know what the terminal number is that goes to the Inertia switch?

Disconnect the Inertia switch one of the pins the dark green and yellow wire should have power jumper it -the pump should come on. No power go back and retest the fuel pump relay, Power present -do something with the fuel pump-I have given you everything I got on ford fuel system
