Ford Taurus :: 2001 - Multiple Fuel Pump Failures
Aug 14, 2011
I have been through 7 fuel pumps in the last 9 months. I purchased the car 1 1/2 years ago with 95000mi from an elderly lady, pulled the car fax and it had no issues and had been back to the dealer every 3000 for every scheduled maintenance and minor routine maintenance. It is a 2001 SES DOHC 24valve.
9 months ago, the fuel pump died right next to the Ford dealer. It had been randomly quitting on me after I would shut it off for a month or so. Then I would hear it priming and knew it would start. Finally, it just wouldn't start after an hour of trying. Of course, the next morning it did.
Took it to Ford, and it wouldn't do it for them, but they thought it sounded like a fuel pump problem. The next 3 pumps they put in wouldn't register a full tank and would indicate that I was low on gas about 50-60 miles before it should, and when filling it, would only take 12 gallons of gas in the 18 gal tank.
The dealer checked the amount left in the tank and verified that it was an 18 gal tank ( which I already knew) when changing to #4 and finally agreed with me that something was amiss. They thought that maybe # 4 would be better because it came from a different place in a different box. These were all supposed to be genuine motorcraft parts.
The next 4 pumps registered a full tank and I was getting about 300 miles before the check fuel light would come on and would take 15.5-16 gal of gas to fill, which was normal. The problem was that they all died after about 600-700 miles. The dealer said they talked to Ford and they kept telling them the same things to check which they did and were all okay. Things like resistance connections. The last pump #7 failed early in the day and still wouldn't start the next day, but did start after getting it towed to Ford. The dealer attempted to order #8, but Ford had put a hold on all the pumps they had in stock. So either they weren't shipping anymore for me or there was a much widespread problem. They installed a Carquest pump this time. This one doesn't register the right fuel in it either. Not as bad as 1-3, but I am getting about 35-40 miles less than I should before the check fuel light comes on and it is taking about 14 gal to fill.
What Ford may be missing when they change these out that I might pass on? They probably wouldn't listen anyway as it took the first 3 before they actually measured the fuel still in the tank even though I had been telling them it wasn't right.
If # 8 works, should I just live with it not showing a full tank, at least it is working. Either way I am afraid to drive the car to anywhere but work and even that is kind of nerve wracking.
At least the pump has been under warranty every time to I get a loaner and they fix for free, but I want it fixed right!

Having a problem with the fuel pump engaging. Warm or cold same problem. When I turn the ignition on I can hear the fuel pump engage and the car runs fine on start. Other times I turn the ignition on and don't hear the pump engage, thus no start. But repeatedly turning the ignition on an off I get the fuel pump to engage and I have start, will run until I shut it down. been doing this for a couple of weeks now. Is this an ignition thing or fuel pump? No wiring diagram. Replaced all relays, battery good. Never did anything with the fuel system.

1991 F250 Diesel. I'm on my 5th heater core in the past 18 months. This last one lasted less than 500 miles. I'm using the Spectre brand from Autozone. I find it hard to believe i could have gotten 5 bad ones in a row. I have pressure checked the system and it's normal. There is no fluctuations in the readings, so I doubt there is a head gasket issue.
I checked for stray voltage in the coolant and the results never got above .17 volts, but it was usually lower than that. I thought I had an electrolysis issue when I noticed the heater core tubes touching the firewall, so for this last core, I insulated the tubes, but that didn't work. I've checked everything I can think of. The truck has 117K miles on it. I don't drive it much, less than a few thousand miles a year.

2004 F-150 heritage : 12 degrees F yesterday. clicked (firewall solenoid) but starter was not pulling amps. After putting a jumper pack on it, after about 30-40 clicks it took off, never to work again.....towed it home with a rope.
2000 F-250 Super Duty : 7 degrees F today, did the same except you could tell the starter was pulling amps. Took a lot of clicks and engaged but I let off too quick, another bunch of clicks and it started. Once I moved it, I tried it a bunch more and it seemed to work, however I do not trust it.
2001 Crown Victoria : 7 degrees F today, the first turn of the key was nothing but a click, and the 2nd turn it worked fine. After moving it worked a bunch more times.
Whats up with the cold temps and the starters?

So my windshield washer fluid sensor popped on a couple of months ago, checked fluid (was full), I concluded that it was a failed sensor. I ordered a new one from ECS, put in last wknd, and finally: the low-level warning light disappeared. A few days later, I was adding some fluid into the reservoir (it was a new bottle and had no funnel) and I spilled a few drops. The spilled amount seemed to drop near the sensor plug, but didn't think it was a big deal. Went into work, came out later to head home, and you guessed it: the low-level light came back on (with a FULL reservoir).
I removed the plug yesterday, blew it out, but it didn't change a thing. Anyway, is it possible the sensor shorted because somehow some of the fluid go into the connection? If I hookup the vagcom, will I be able to tell if there is an issue (I know it didn't before when the first sensor failed). Is there even a fuse for the fluid sensor?

Fuel pump does not work in Cold Weather, but works fine in warm weather? Will replacing the pump solve this or is there a bad sensor somewhere else causing the problem?

I have a 2014 Camry SE with 35k miles. About six weeks ago the drivers side front power door lock actuator failed and was replaced by the dealer under warranty. Last week the front passenger side actuator failed and was replaced. Today, both rear door lock actuators stopped working.
I searched the forums and didn't find anything like this happening to other owners. It sounds like I have something burning up the actuators. I am very concerned because the new car warranty is up in less than 1000 miles and I could have an electrical problem on my hands. The actuators that have been replaced seem to be working fine. How I can handle this?

2003 Toyota Matrix with 217,000 miles (most on a rural mail route). Check engine light stays on with readings for multiple misfires, all four coils (which have all been replaced) and just replaced fuel pump. Gas mileage has plummeted.

I have a 1997 Toyota Tacoma 3.4L ... After having some problems a week ago with the truck dieing at every stop sign or any time my foot wasn't on the gas. Eventually the truck would not start at all. I finally got a CEL that gave me P3040 (Camshaft Position Sensor Circuit Malfunction) So I changed out the sensor and the truck fired right up and ran for 3 days.. Now the truck does not start again and I am getting the same CEL code.

Having seen the rather catastrophic outcomes that are possible with inverter coolant pump failure, I've thought a bit about adding a flow sensor in the coolant path. I even went so far as to buy a flow sensor, which would probably do the job. However, it's somewhat heavy, and then there's the plumbing job to take care of. Seemed somewhat challenging to pull off.
Since this aborted endeavor, I began thinking about ways to detect surface turbulence at the top of the coolant tank, and am now thinking that might be easier to pull off, even if it requires programming a PIC to do the monitoring. My current thought is to install an LED and optical sensor in the cap, and measure light intensity received.

The dealer has replaced the DMTL pump 4 times on my 2004 BMW325. The last time the dealer checked the gas cap and smoke tested the fuel system - all OK. I do not overfill the tank. The pump has failed again and I am getting tired of taking it to the dealer for a new pump. Fortunately it is under warranty but I am sure that there is something else causing these pump failures.

I have a 2005 Ford Taurus. We had an $1800 rebuilt transmission put in 8 months ago and it's already giving us problems! The engine light has also been on. We took it to autozone and multiple codes came up. We've already put way too much money into this piece of shit and I don't want to get screwed by another mechanic! Where do we go from here? Is there anything we can fix ourselves? The codes are p0300, p0301, p0305, p0316....

I've got a strange problem on my '01 F-150 4.6L 4X4. When the outside temperature gets below 40-45 degrees the fuel pump won't always run when trying to start the truck. You can cycle the key switch on/off 8-10 times and the fuel pump will run. The engine will then start and run fine. You probably have to use this procedure 80% of the time. It started this last winter. I replaced the fuel pump relay in the power distribution box under the hood but that did not work. When the outside temp warms up the problem goes away.

My brothers 2001 is having an issue with the fuel pump. It has a random no fuel pump basically the fuel pump does not come in, he turns the ignition off then back on and you can then hear the fuel pump turn on and the truck starts and runs normally. I'm not looking forward to dropping the tank to replace the sending unit so I was thinking maybe the relay is the issue? I'd eater do that than a sending unit job...

I have a 2001 Ford F250 truck -- it was stalling out (which was diagnosed as a faulty fuel pump), so I had the dang thing replaced. But nearly 6 months later, it's randomly stalling out again when I put it in reverse or stop at a light.

I have the gas 5.4l in my 01 F250 Super Duty. I had to change out the leaking Heater hose before I could attack this other issue. The truck starts when it feels like it. I changed the fuel filter and it started fine. Then the next day it wouldn't. Later it would. However each time it does start it dies when throttled up. I am down to thinking it is the fuel pump. My question is, because changing the pump sucks about as bad as changing the heater hose. Can I install an inline fuel pump and deal with the sump pump in the tank later? Are there any Cons to doing this?

I have a 2001 ford escape V6 3.0l. Dropped a new motor in it, got everything running fine. Surprisingly the most frustrating part was when we mixed up the order of the front 3 coils but we got it!
It drove "ok" for a week and a half. Then it started to shudder at 45-55 mph. Got it home that afternoon and started to diagnose why it would shudder. Suspect its not shifting right.We started to diagnose what was wrong, made some adjustments to IAC, MAF and checked a few other things. We then went to test drive, started up fine, drove up the driveway 50' and it died. It didnt sputter and die, it just lost all power and died.
Got it back in the garage and tried to get it started again. Turned Key... nothing. Dash lit up but starter and fuel pump didnt fire. Odometer reads ------. I can jump the starter by pulling the starter relay. Same for the fuel pump. I use a jumper wire between two pins and I can get the starter to crank and the fuel pump runs when I jumper wire the relay too. So I know its not a bad starter nor a bad fuel pump.
Odd part of everything is that It drove just fine that day (other than shuddering). Then started just fine, then died. When it died we were making a sharp left turn in the driveway. We've messed with the steering wheel because it was "accidentally" put upside down when we dropped in the new engine. Could something have grounded out in the steering wheel? Air Bag? Maybe a problem in the clock spring? What would stop it from The fuel, starter and spark all at the same time? Bad PCM? Grounding issues?

My 2001 4.6L F-150 has been sitting on the driveway, used once every 2 weeks or so for the last 3 yrs. I came to start it a few days ago and it kept turning over but not starting. The key security chip is working, battery is charged, all plugs are firing, fuel pump fuse and relay check good. When I turn the key to ON, sometimes I hear the fuel pump priming, other times it doesn't. The times it does prime, the truck fires right up.
The times it doesn't prime, engine won't start. When the pump does prime, and while the engine is running, the pump makes a noticeable buzzing sound, much louder than normal. When the pump primes. fuel pressure measures at 42psi in the ON position, 36psi with engine running, and 46psi with engine running and vacuum hose removed. I believe all these are within specs.
My question is this: Is it safe to assume that the pump is going bad and will eventually fail completely? My second question is (and I know this can be debated til the end of time) should I get the Motorcraft or aftermarket? I have Airtex, Spectra, Carter, and Delphi available locally.

I have a 2001 f350 v10 that has been giving me fits. has 88000 miles. cranks and starts when cold or fuel pressure is below 40 psi. SES light will flash when it stalls and fuel pressure goes from 30 while running to 40 and the fuel pump runs continuously when this happens and truck will not start. replaced crank sensor and fuel pump was changed about two months ago. if I relieve fuel pressure it will start and run for short time then stall and fuel pump stays on. all fuses are good. I am at a loss.

What sensors etc. besides the mass air flow sensor have to be working in order for the fuel pump to run? I get no fuel from the fuel pump even though the engine is cranking. There must be other relays, fuses, or sensors I can check even though all fuses I can see are ok. How can I check the EFI relay to tell if it is ok?
