Four times is rediculous there has to be a logical reason why this is happing. Either there is a electrical short in wiring damaging fuel pump motor or in my case after the new motor was installed they pinched the wiring damaging the replacement fuel pump motor. The car was driving for a long time ok till the pump went out again. One other thing i would change is the fuel relay note: the relay is actually several relays intergrated into one module mine was located on top to one side of the radiator. One other thing the fuel pump inside of the fuel tank needs the gas to Cool the electrical pump to prevent overheating the fuel pump motor so keep at least 1/8 to 1/4 full at all times.

Wiring over tank could be pinched OR look for wiring connection around your distributor or running under dist for any signs of green corrosion.
Problems have been found there also.
#125 of 177 2000 Taurus Fuel pump issue
Oct 02, 2011 (4:01 pm)
Hi folks. Im new to this group. Im having a problem with the ladies 2000 Wagon. She ran it out of fuel...After adding fuel...No start. Towed it home, pulled tank and found that when supplying 12V to pump in the garage, the pump ran great. The problem...and what is Baffling me is that when I hooked up wiring and lines under car and turned key...all the pump will do is run for approx 1 or 2 seconds and shut off...HELP!!!!!! Point me in a direction if at all possible..

The pump is doing what it should. When the pump builds up pressure it will shut down with the eng off and the key on.
Find the pressure test port on the fuel rail, remove cap and press down valve with small screwdriver, make sure you DON"T have your face over this valve. It should shoot a stream of gas for a sec. If you have the key on the pump should kick on again.

as with the many other posts had intermittant starting. tried listening for fuel pump heard nothing. cranks fine until battery died, jumped started and car actually started? twice. but didn't work after that think it must of been coincidence or last bit of life in pump with the extra voltage maybe. tried banging on tank while cranking, no help. swapped relays around, no help. no fuel in fuel rail. has ignition. checked shut off switch-not popped. pulled off connector to switch- reading 11 ohms though pump one previous post said should be like 17ohms. getting 12 volts at switch connector for 1 second then drops to like 6.7 volts. jumped 12 volts to switch connector still don't hear pump. so i guess safe to say needs pump or harness smashed issue. what do u think.

The pump works perfectly in the tank..connected to 12v and in the garage..out of the car. When sitting on the ground under the car and hooked to wiring harness, with output of tank going to a tank, when the key is turned on the pump starts and runs approx 2 sec then shuts off. It isnt building pressure as its running into a tank. Before I fully install the tank and lines I'd like to be sure this is doing what its supposed to be doing. Thanks for the prompt response and I hope Im on the right track...Ed

that doesn't sound right. now i am only trouble shooting this system for a couple hours myself my post next to yours. but if i read yours right how can the system be satisfied and turn off pump if you are pumping into another container and not building back pressure. should not shut-off shouldn't it. unless something i still don't understand.

If you are not building up pressure, and you have 12V going to pump, then
the pump should remain running.

Wellllllll, thats what I was Afraid of...Now my problem seems to be...What is shutting off the pump?? And if its a Relay..Which one is it and its location. So far this has been an annoyance but Not a hard job. The hardest part so far being the communication to get the info I need to fix my ladies car.
Could it be a relay?? Could it be because all the fuel lines and other connections werent completed? PLEASE GUYS/GALS, if you can shed some light please try..Im all ears as we are expecting snow soon and hers is the only registered vehicle at the moment..Besides my bike..Thanks for the responses and all the help!!! Sincerely, Ed Williams

i am reading the description and operation. are u just turing key to on to check because it says the pcm also looks for engine rotation. so see if it stays on longer when you have someone go all the way to start with key.
