93 Ford Taurus fuel pump location and how to test it color of wires to test?

Answer 1

The fuel pump / fuel gauge sending unit is located in the fuel tank. You have to drain the tank and lower it, to get to the round access hatch on top of the tank. You remove this access hatch by screwing it counterclockwise. The fuel pump and fuel gauge sending unit are located just below the round hatch.

You can tell if the fuel pump is turning on, by turning the key to the electrical system "on" position (not the engine start position). You should be able to hear a low hum as the pump runs for a few seconds before it builds enough pressure and shuts off.

There is also a relay module that sits on top of the radiator. You have to pull a flat plastic cover off the top of the radiator to expose it. It's about 3 1/2 x 5 inches and has about a dozen wires or so connected to it. This relay also controls other things like the electric cooling fan etc. I heard the pink wire with the black stripe controls the fuel pump, but cannot swear to that. I needlessly replaced the fuel pump when trying to diagnose a fuel pump problem, when the problem was with the relay. The Ford dealer wanted a fortune for the relay module. I wanted an original Ford part because I heard stories that after-market parts were really trouble. So, I went to a junk yard and got one for under five bucks. Take the old one to the junk yard so you can match the numbers. Ford made a lot of different relays that look the same on the outside, so make sure you match the numbers on the parts.

AnswerThe fuel pump is in the fuel tank on the top side. Most of the time if you take out the rear seat, you can accesss the fuel tank top side to get to it. I hope this helps you. Good luck. AnswerThe pump is in the gas tank. See if you have a plate over the pump area. AnswerIt is in the fuel tank. You will have to jack up the rear as high as you can, and secure on jack stands. You will need some help, and hopefully the tank is nearly empty, otherwise you are in for a battle. The tank is held in with two long straps. Also there is a filler neck and vent hose at the rear of the tank that will have to be disconnected. The tank will have to be lowered and removed. I recommend some help and a good floorjack, with a piece of plywood between the jack and the tank. Lower the tank slowly while disconnecting fuel lines and wires as they become visible. Onced the tank is removed, you can remove the fuel pump lock ring on top of the tank. It screws off counterclockwise, but it is stubborn. I use a hammer and a big flat screwdriver to get it loose. From there it is self-explanatory. Replace the pump, and reassemble. AnswerI actually just helped a friend with this problem. First, siphon as much gas out of the fuel tank as you can, to make it lighter. Next, disconnect your negative battery cable. Jack up the rear of your car and put jack stands under it so you can take out your jack...you are going to need to do that before you can proceed. Then disconnect the lines right at the fuel filter. Look at the gas tank, and you should see two steel straps wrapping underneath it. They should be bolted in toward the back of the car, and I believe the bolt head size is 13mm or 1/2" socket. Move your jack under the fuel tank to support the tank's weight (but DON'T jack up the car by using the fuel tank as a jacking point, or it will crush the fuel tank). Use an impact gun or a rachet and loosen the bolts holding the straps, but don't take them all the way out just yet. Grab a screwdriver and take the clap off the filler neck so you can wiggle it off the tank. Then, with your tank fully supported by the jack, take out the strap bolts. Next steps you will need to do a little thinking for yourself because the tank will need to be wiggled out of a tight spot between the exhaust and the firewall. It can be tricky, but it can be done. Have someone help you by letting the jack down slowly, and from time to time help you wiggle the tank from tightly wedged spots. When the tank is down you should be able to unhook the pigtail hook up from the fuel pump. Slide the gas tank out from under the car, and you can use a specialty tool from an autoparts store or use a flathead screwdriver to slide the ring loose. Then the fuel pump should slide right out. AnswerYour fuel pump is in your Fuel tank AnswerThe fuel pump is located in the fuel tank. It will be necessary to remove the fuel tank to gain access and replace the pump. Once the tank is removed, the fuel pump will be under the large lockring on the top of the tank. AnswerTo test whether the fuel pump is basically working at all, turn the ignition key to the electrical "on" position (not ignition start), and listen for the sound of the pump activating. You can easily connect a pressure gauge to the line near the injector rails and check if pressure is within specs. Good Luck. AnswerIt is in the fuel tank.
