No power to fuel pumps, or to 10 amp fuse (for fuel tanks).

anything from overheating -power spike -short-loose connection -component failing

How do you know it is not kicking in. Have you done a fuel pressure test? get the Chilton or better yet the factory repair manual to your specific car and trouble shoot the fuel system. Two fuel pumps not working there is an issue with the power getting to the pump. Test for power. either a fuse or relay or safety switch is open. The repair guide will tell you. Chilton or Haynes cost $25 the factory $100 likely.

Yes, it has an electrical fuel pump located in the gas tank. First check the fuel pump fuse located in the fuse panel on the left outer side of the dash. You can only access this panel with the driver's door open. It is located near the black button for the dome lights and chime.

It is a 20-amp fuse. Replace it if it is blown, but ONLY with a 20-amp fuse. The wire harness for the fuel pump sometimes goes bad, or the pump motor, or the wire harness inside the tank to the pump motor. If the blown fuse is replaced with a larger-amp fuse, you could cause a fire or explosion.

If it blows the replacement fuse, stop. Fuses blow for a reason, 9 times out of 10. Call a tow truck to remove the truck to a qualified repair shop.

The primary (coils) side of the fuel pump relay is powered by the CRANK fuse (10 Amp) located in the instrument panel fuse block. This fuse is hot ONLY when the ignition switch is in the CRANK position. The secondary (contact) side of the relay is powered by the ECM-B fuse (20 Amp) which is hot at all times. This fuse is located in the engine compartment fuse block. The electric fuel pump in the tank only operates during engine cranking.

To check to see if your fuel pump is working have someone run the ignition key while you listen at the fuel tank of your car, remove your fuel cap put your ear next tank hole and then have your helper turn car on but just so the dash lights up not to start the car.You should hear the fuel pump actuate or hum for a second or two,and if you don"t hear a hum then move to the fuses and if they are good move to your fuel injectors then check your plugs wires and Cole pack. The fuel pump relay is in the fuse box under the hood of the Taurus next to the battery its a black box and is the main power distribution box for your car. The fuel pump fuse is number 10 (A) in the power distribution box. On a 1998,1999 you can swap the fuel pump relay (B) with the EEC power relay (C) to check to check fuel pump operation.the best way to check your car is to use a OBD 2 car reader.hope this helps but you can also buy a Chilton manual if your willing to get your hands dirty and have some mechanical ability you can save your self a lot of money.I believe the going rate for mechanics now is about $105 dollars an hour and thats here in WA.State.

The fuel pump relay is powered by a fusible link connected to the starter solenoid on the positive battery terminal. That fusible link feeds the 10 amp fuse near the relay. You can test the fusible links with a 12 volt test lamp. If the fusible link test okay check for an open circuit in the wire between the link and the 10 amp fuse. Hope this gets you fixed.

u need to buy a repair manual at a parts place or go chiltons online-books are mechanix tools also

replace relay

Have you checked the fuse box under the driverside dash? If memory serves it should be a 15 to 25 amp fuse. I would suggest you check all of the fuses with a fuse tester. And take a close look at all the grounds.

try running power from relay to the inertia switch through a jumper wire and see if pump works. you might have a pinched or broken wire in the factory harness.
