I pulled all the fuses out shined up the terminals and the check engine light went out and the fuel pump works now( what a cheap fix.)

try cleaning up your 30 amp fuse for pump and check all your grounds
#158 of 177 2000 ford Taurus duratec v6 24v fuel problems
Dec 31, 2012 (1:51 pm)
check engine light is on= code P0191...Symptom's are "No start but cranking has spark"...first key turn no fuel pump prime noise heard.... symptom comes and goes in any type of weather or temperatures On second crank if you turn the key to off and than turn it back to crank ( if i hear the fuel pump prime) than the car starts..but if i don't it will just crank but sometimes after i hear the pump prime and starts it stumbles like it wants to die and it does..(and sometimes it doesn't stumble) So i do this a few times making sure i hear the pump prime and if i get lucky it starts and runs fine and off i go...Once the car is running i have no problems with staling at stops,highway speeds or idle.. Symptoms appear at first start no matter how long its been sitting (5minute to 24hrs)..youtube has a real good video on this "Ford Electronic Returnless Fuel System Diagnosis (Part 1)"..did all the Diagnosis on the black box module connecters and the inertia switch and everything passed...So what the HELL is up with this car? anyone thinks it's the Fuel pump? or something else? Any feedback is appreciated

Wow! thanks, gsc01972. that one must have cost like a new fuel pump! If anyone has similar problem, I'd measure voltage with multimeter on the connector to the inertia switch to diagnose that thing: on 2000, the fuel pressure regulator (or "fuel pressure sensor") is an unusual electric switch feeding between PCM and a fuel pump voltage regulator which will turn up or lower the voltage to the fuel pump to control the pressure that way (instead of just letting excess gas flow through a return line back, as in older Taurus). If the voltage was present in both cases (when there's humming noise from the pump, and when not), that would be most likely be pump itself..

This problem was driving me nuts.....yeah..it is costly...on E-bay around $113 NEW...don't know what it is at the dealer but im not buying it!! ill go to the junkyard and buy one for under $10..Hopefully its a good one! Yes im cheap...specially on a 13yr old car that has no selling value. On KBB it has value but on Craigslist a really nice one you can get for under $2200 in the NEW England states ....In the end i hope this helps anyone that has this kind of problem....Do it yourself and SAVE MONEY....In the age of information..

yeah, junkyard can be a treasury house for some parts! Taurus is a great car, 13 years isn't really an age for it..

Purchased this car used in 2010. Currently has 57k original miles. Last summer (2012) after a 20-30 minute drive, and then parking for 5-10 minutes the car started fine, but stalled about 3-4 minutes later and would not restart. Turned over fine, but (apparently) no fuel. Tried it for nearly an hour with no success and finally called AAA. Forty five minutes later, the tow-truck driver decided to give it a try and it started fine. Drove straight to the local shop and left the car with them. Nothing on computer diagnostics and after 24 hours they couldn't reproduce the problem. Flushed the injectors to be safe. Three weeks later, the exact same thing happened. Thirty minute drive, 10 minutes in the store, and then stalled while leaving the parking lot. Tried to restart every 15-20 minutes, and after 75 minutes it started fine. Suspected a fuel problem or vapor lock (been told that a 2002 should not have vapor lock issue). Switched stations and added Heet with each full tank.
Problem didn't reoccur till January 2013 (nearly 6 months). Now it has happened 5 times in 2 months. Three of the 5 times, it has been during the day (living in hot Florida) after a short drive, stopping for 5-10 minutes and then restarting. Always lets me drive a couple/few hundred feet before stalling. Two other times it happened after being parked at work for 6-8 hours. Waiting 70 to 90 minutes, trying every 15-20 minutes has gotten me back on the road each time.
Happened again today, after a 1.5 mile drive, and being in store for 10 minutes. That was 15 days since the last occurrence, which has almost identical symptoms. Already replaced the fuel pump relay and thought the problem was solved, but it reoccurred after 10 days. I am prepared to bring the car to a Ford dealer and probably get the fuel pump replaced (I am really strapped for cash, otherwise I would replace this otherwise great running car). But after reading some of these posts, not sure if that will be a long term solution. The grounding issue is interesting. Anything else, like these mentioned diodes (not sure if that's in my 2002) or a fuel pressure regulator, that would cause such an intermittent problem. I "definitely" get no sound when I turn the key to on and the car won't start. As soon as I turn to On and hear the hum, I know it will start fine. Has never happened when I leave for work in the morning for the past two years. Has never stalled on the road while driving. Only as described above. Not really prepared to put the car up on jacks. When I was 25, that was a possibility, but at 57 not ready for anything like that. Still seems like an electrical problem to me.

i would replace the fuel pressure regulator..its on top of the engine next or on the fuel rail so you would not need to jack the car up...Mine did the same thing....(That part new is at least $113) If you don't have the money now and you still want to drive the car and don't want to wait hours till its fitz are over...like i said...turn the key to "ON" not running the engine.. listen for the pump to turn on. If you hear the pump turn on than start the car.. your good. If you don't hear the pump then turn it to "OFF" meaning turn the key towards you all the way than turn it back to "ON" again...Repeat till you do hear the pump...There is no real wait time to "Repeat" just don't do it to fast or slow..."on" ,"off " listen, "on" ,"off " listen,"on" ,"off " listen... smooth...just like opening the front door of your house with a key...Good luck
