if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing
sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: 1996 windstar relay
The fuel pump power on the Windstar is controlled by a component called a Constant Control Relay Module (CCRM).
Its located located on the driver's side of the engine compartment.

It's under your hood, in one of those boxes, and should be marked. Your pump won't cut in if it's fried either. Check to see if there is power at the pump. Maybe you just have a loose wire. You can always hope!

Did you check the fuel inertia switch in the passenger side kick panel ?
The fuel pump is powered :
the fuse to the fuel pump relay.
The fuel pump relay to the fuel inertia switch
The fuel inertia switch to the fuel pump itself.
At the fuel inertia switch in the kick panel, power from the relay is the Dark Green w/ Yellow stripe wire and the pink w/ black stripe wire is the power. from the fuel inertia switch to the fuel pump.
If you jumper the fuel pump relay, you should hear it run. If not pull the fuel pump relay, and check the pins in the relay socket, pin 30 should be the power from the fuse.
If you have power at pin #30, jumper the relay socket as shown with the red line above, and check the dark green w/ yellow stripe wire at the fuel inertia switch for power.
Press the button on the top of the fuel inertia switch, and check for power leaving the fuel inertia switch on the pink w/ black stripe wire.
This is tests good, check for power at the fuel pump, same pink w/ black stripe wire.
Fuel inertia switch info is in the owners manual, If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :
