SOURCE: fuel pump relay
I have found the relay at my local auto parts recycling center, after many hours of troubleshooting, I also found the PCM to be faulty. A replacement computer is on order. This model has been modified by prior owner removing the inertia safety switch. A replacement is also being sought. A similar problem occurs when the ECT (engine coolant temperature) sensor is destroyed.
Whatever you do, DO NOT REMOVE THE INERTIA SAFETY SWITCH. This does protect the fuel pump and related circuit. Also linked to the fuel pump circuit is the main relay, and the injectors.
If you find the thermo fan starting within seconds od rotating the engine, the problem is the main relay earth, PCM (needs replacement) and/or the fufel pump relay. This is known as LIMPO HOME MODE.

SOURCE: 2008 Ford F450 fuel pump relay fuse keeps blowing.
the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.

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 :

SOURCE: where is the fuel pump relay on the 95 ford taurus
Hello , fuel pump relay location is in the relay box by the radiator. The fuel psi regulator is on the fuel rail itself. The regulator looks like a small disk about 1.5inchs in dia. It will have a vacuum line running to it.
