Which pump, fuel or water?

If you are asking about the fuel pump, there are two fuse panels. One is under the dash and the other one is under the hood. I do not know where the actual fuse for the fuel pump is, but the control relay for the fuel pump is located under the hood. In the engine compartment. Your owners manual will show you which relay controls the fuel pump. You may even get lucky and find a schedule of the fuse panel layout on the panel itself.

You may also want to reset the inertia cutoff switch located in the trunk. This stupid device shuts off your fuel pump if you get hit in the rear. Cops like to hit running away cars (cars who refuse to stop) in the rear in an attempt to trip the fuel shut off switch. Look for it in your trunk and press it to reset. My old Ford Thunderbird had it in a little hole in the trunk just behind where the license plate is mounted. Others have it on one side or the other in the trunk. BUT good luck finding it if you don't have a manual. Some Ford models have it under the dash on the passenger side of the vehicle. So good hunting! IF I owned a Ford today, my first project would be to find that stupid device and jumper it out! I got hit once in the rear by a sleeping/speeding armored truck driver. My fuel pump turned off and I was not able to get out of his way so he hit me again! Was I ever PO'd when I found out that Ford had designed that into their system as a so-called safety feature!

If your fuel pump still does not operate, then check out the first youtube link below.

I tried to find a manual for you online but everywhere I go they want me to sign up to be a member. I'm not going there, but you can.

Don't force the fuel pump to run. A friend of mine thought he was clever and wired his fuel pump to stay on, and not long afterward learned how to rebuild an engine. It turned out his oil pressure was low and the oil sensor tripped the fuel pump cutoff.

So, check your oil before anything else.

The 05 Taurus fuel pump is controlled by a relay and the fuel pump driver module which is controlled by the PCM to adjust power supply voltage to the fuel pump based on fuel pressure sensor values/readings. The power circuit wire from the relay also runs to/through an Inertia Fuel Shutoff switch which cuts power to the pump in case of an accident. The pump relay should have two power sources/fuses and a ground path for the coil side of the relay and a power path circuit to the inertia switch/ module/pump. You can try to replace the relay with another known good one. Like the A/C clutch relay… And test to see if you do get power for the two power sources at the relay. Fuse 16 is one power source… Not sure of the other. And test the relay for a good ground. If the relay does have good power and ground and is working, also test/check the inertia switch to make sure it's not tripped… Reset if needed.

If the circuits are OK and you get power to the pump, then you may have a bad pump or bad ground path at the pump… Check that as well. 3 reasons why the pump won't work… No power… No ground… Or bad pump.

You can bypass the relay by running a jumper wire from terminals in the fuse box that correspond to terminals 87 and 30 of the relay… 87 should have incoming power and 30 is the power path for the pump circuit. Terminals 85 and 86 are for the coil side of the relay… One should have power and one should have ground.

Or you can run a 20 amp fused jumper wire from the car battery positive terminal to the pump power wire (white/red stripe wire) to see if it runs as long as the black ground wire/path for the pump is OK. Use an inline fuse holder (sold at parts stores) and 20 amp fuse in the jumper wire to keep from frying anything.

If the pump relay clicks when key is turned on but pump does not run, it could also be a problem with the fuel pump driver module which controls power to the pump or a PCM or wiring/fuse issue. Check for bad fuses first of all.
