Changed the fuel filters. No issues in replacing.
Primed them by the book - key on 30 seconds 6 times
Now I have low pressure warning and reduced power.
All parts were FOMOCO...
So, I just had the fuel pump replaced on my '15 6.7 a month ago and it just died again. (next day edit: it didn't actually die, it showed all the same symptoms)
Same symptoms: whining sound, low fuel pressure warning, reduced power warning.
This time I'm 50 miles from home so I pulled off the road before it shut off. Interesting, I was in a hilly area and my low fuel warning came on too. We are waiting for a tow. I was considering trying to push on but don't want to get stuck in a dangerous spot on the highway. We're in a church parking lot.
So, last time this happened I was on flat road with about a half tank of fuel on a lunch break. I ran a mile after the warnings came on to feel out the issue and to see what would happen. I happened to be only about a mile away from my dealer so I drove that way. I got reduced power warning and then it cut power on me (limp mode). I made it to about 100 yards away before it cut off.
This time, I was in a hilly area at night on a windy two lane road with no shoulders in the woods. I was miles from civilization and was showing below a quarter tank of fuel. ~100 miles to EMPTY. I got the low fuel pressure warning first and then the reduced power mode before the whining noise started. I was climbing a hill on a curve at the time. I drove a quarter mile and then pulled off the road into a parking lot so I wouldn't be stuck on the shoulder. It didn't actually go into limp mode.
I let it sit a few minutes, talked it over with the wife and decided to call for a tow. After talking to the tow truck driver who said he would be an hour because he had to go find a bigger truck, I decided to see what I could do while I wait. I fired it back up and the fuel level dropped to below 1/8 and I was now showing 33 miles to EMPTY. I was parked on a hill with the back end up. I had backed the truck into a space to make it easier for the tow truck driver. I let it run a minute, checked for leaks and it seemed to run fine with no studdering or additional warning lights.
CEL was on but no new warnings. I put in my code reader and pulled the P0087. Just one code. I revved it a bit to see if there were any issues. It seemed fine so I decided to try my luck. I started driving towards home with the intention to stop at the first diesel station to fill up. Truck ran fine. After two minutes of driving gently, heart racing, my fuel level came back up and it now read 88 miles to EMPTY. I drove 11 miles to the nearest station and filled up. No issues. I shut it down. I fired it back up. Still no issues so with a full tank, I drove home the remaining 30 miles without issue.
Planning to take it in to the dealer Monday to get it checked. Could this be from an air pocked due to low fuel level and hilly terrain? Is my new pump dying already? Is there something else going on inside the tank or elsewhere?
I just had my first fuel filter change (about 9,000 miles). After the shop changed both fuel filters with factory Ford ones, a check engine light came on and a "low fuel pressure" warning, along with a "reduced engine power" warning. It also stalls a lot and takes a long time to restart.
Obviously, they didn't do it right. I suppose there is air in the lines or something didn't go back together correctly.
My '06 seemed to purge itself, but this truck obviously won't. It is not even driveable to get it back to the station, to see if they can correct the problem.
The thing is, I watched them do it, so if someone can ask me the right questions as far as what I saw, maybe I can lick the issue in the driveway myself.
I changed both fuel filters on my 2015 F350 6.7 I turn the key online for 30 seconds then turned it off for total of 6 times when to start the truck this morning after driving it yesterday and it took a little bit longer to turn over before it finally did, did I miss something up that I do something wrong. So I let my truck warm up this morning after going to start it at took a little bit longer for it to turn over I turned it off wait a few seconds then turned it back on and she started up how she used to perfectly fine does it just need to go through a drive cycle. This is the second fuel filter replacement nothing was wrong with the other ones I'm at 40000 miles now ... also it seems like the fuel filter on the frame rail is louder if you put the filter in upside down on that will it fit stupid question I'm sure I did it right but thought I'd ask before I tear it apart....
View 14 Replies2011 F250 6.7 Had the fuel filters changed by the dealer today. No noticeable sounds when I left the dealership, & no fuel stops on the way home (120 miles one way). When I got home, before shutting off the truck, I heard a loud groaning/singing from inside the truck. With the truck still running, I get out, & the groaning/singing is very pronounced....never heard this before & appears to be emanating from the fuel filter underneath the truck.
I turned the truck off, then turned the key back to the position that the fuel pump turns on, and wow, the pump is very loud. Definitely something going on because when I turn the key for the pump to turn on but not start the truck, I can feel the vibrations of the pump working from inside the truck and when listening from underneath the truck, it is very loud. Before today, the truck never made this noise and never heard the pump before.
1st diesel was a 1997 F350 dually (White Lightning). Upgraded last year to a 2015 F350 (The Rocket Sled)- the kids named it hahaha. Had to take the 6.7 (9200 miles) into the shop... Last Sunday I took the truck out and about 5 minutes from home I got the low fuel pressure warning. Pulled over and tried to purge air out of fuel system- the low pressure pump was making a terrible racket. Turned around and limped home- reduced power came on soon after. Parked it until I could get to the dealership on Tues. Long story short- dropped it off at the dealer (low pressure pump still making noise/ no low fuel waning, just CEL light).
Called to check status today- dealer can't seem to duplicate problem. Service advisor said if mechanic can't find anything wrong, service manager was going to take it out and try to duplicate. The is the 2nd time I've got the low fuel pressure warming. The first time (around 4000mi. ) was in winter- I changed out fuel filters and it went away. I was towing the 5th wheel. Just had to vent-I have to get this figured out. I wouldn't thing the filter could get clogged within 5k miles. Have a camping trip scheduled next week!!
My truck gave me low fuel pressure and reduced pressure limp mode at 21,000 miles. The fuel and air filters were changed at 16,000. The dealer said all they found was the fuel filters (at 21,000) were what needed to be changed. Also, why does my truck hum??
View 14 RepliesI have seen this pop up on the truck I think 3 times now over the first 4000 miles on the truck.
Usually it's when I'm on the highway around 70mph or so.
It comes on for a few seconds, then goes away. I do have an exhaust / tune on the car.
Low-pressure fuel warning came on two separate times Sunday ... I know what caused it the fuel gel 18 below not enough anti gel in the tank no big deal warm the truck up everything's fine now no more warning lights coming on does the dealer need to reset anything I guess I'm asking did it throw a code that needs to be cleared? Its running fine now I guess I'll just have to put a little extra in when it gets that cold wasn't expecting - 18 checked drain no water just gel up could here the pump under the truck fighting to pump for a few minutes.
View 14 Replies65 miles an hour driving down the interstate (I-5) pulling my 5Th Wheel and I look in the mirror and I see at first what I thought was smoke coming from the trailer and then I glanced at my dash and up pops "warning of Low Fuel Pressure". I pulled over as quickly as I could and when I stopped there was diesel fuel spray coming from under the hood. Turned off the key yelled for wife to get out of the truck now. Popped the hood and there was fuel dripping from the engine the all the way to the rear bumper and the front of the trailer.
Since I just had Ford service the truck and change the fuel filters three weeks ago I knew exactly what happened as I looked at the fuel line and seen the green retainer clip wasn't seated properly to the filter canister. I pushed the line in and seated the green clip. What I don't understand is I have driven the truck 200 miles since it was serviced. I re-attached the line and made sure the clip was seated correctly, poured 5 gal of water on the engine plus after using a roll of paper towels to soak up fuel. I didn't want to panic the dear wife but it could have very easily all went up in smoke!
What a mess it made of the Trucks undercarriage and 5th wheel. Going give a call to Ford tomorrow to hear what they can do to clean up this mess.
Question? This happen on a 6.7 after a filter change?
Ok here is a good one. Had a low fuel pressure warning so took it in for service. The warning was intermittent. They replaced fuel filter first, but apparently the low pressure fuel pump needs to be replaced.
Service dept is indicating that the fuel pump is not covered as part of my CPO (certified pre owned) 100K drive train warranty or the extended warranty that this dealership sold me. (wasn't a ford plan but was the one they recommended that would cover everything). Lodged my complaint with the Service manager and waiting on a call back.
Does this make sense to any of you service writers out there
Getting reduced engine power warning with no other lights on the dash and what is probably causing it. The truck is a 14 f450 cab and chassis model. I had just had it to the dealer for this problem and the check engine light was on and the said there were two sensors going bad on the exhaust so they changed them out and sent me on my way. Well after driving the truck around all day and not one issue it had just decided to set the rep warning again but did not set off any lights...
View 7 RepliesReduced Engine Power warning and fuel leak? While towing our 37 Fiver uphill a couple of days ago, the warning popped up along with the CEL. Indeed, the truck did lose a tremendous amount of power. When I found a safe place to stop, the diesel smell was terrible. Further inspection revealed that fuel was dripping down the side of the engine from somewhere above the oil filter. I limped along another 15 miles to the campground and unloaded the 5<SUP>th</SUP> wheel and brought the truck in to the dealer this morning. They aren't giving many details of their findings thus far. They say that they've talked to Ford engineers and that they'll have to put a dye into the fuel to detect the origin of the leak. They suspect the high pressure fuel pump, but by the time they remove enough "stuff" to get to the pump, they can't run the engine to witness the leak. This is my first Ford in 30 years behind the wheel and my first diesel. After 8k miles on the truck.....
View 14 RepliesA month ago I changed engine oil, oil filter and both fuel filters. All replacement filters are Motorcraft and my mileage is off a solid 2 mpg after the fuel filter replacement.
View 14 RepliesI have been getting a low fuel pressure warning every morning now for a couple of weeks. It normally goes away after the truck warms up, but yesterday it came back on later in the day after a brief cool down.
I am already running ford antigel. I have run cetane boost in the summer and antigel in the winter since new.
Is this considered part of the 100,000 engine warranty or bumper to bumper only?
Truck has 30,000 miles on it, but outside of 36 months.
I'm disappointed in the reliability of this truck to be honest.
Driving back from the funeral and get a Low Fuel Pressure Warning message PPP up in the info display. No CEL's etc thrown (yet?). I have PM23A anti-gel in the tank already but stopped for diesels no poured more in. At the same time, I hear what sounds like an electronic motor making a whirring noise in the dash around the area of the under-hood fuel filter. Also sounds like there is the same noise from the back fuel pump. I assume it's the fuel system starving? Calling the dealer now, but going to continue pressing on cautiously until the truck tells me otherwise.
View 14 RepliesHow many miles should I go before changing fuel filters and air filter?
View 14 Replies2013 6.7 F350 13,500 miles... Changed the fuel filters and got them bled out and truck runs OK but have a whining noise from the engine compartment fuel filter area.
View 14 RepliesIve had my 2011 for 20 months. I have 7,300 miles. I know the manual states changing around 22k but do you think time is a factor as well? I wont hit 22k for two years. Truck will be 3.5 yrs old. Should I just change them at 10k and see how they look? Don't want to waste the money either if its unnecessary. I use it 50/50 towing/unloaded.
View 8 RepliesI had my fuel filters changed at the dealership today on my '15, and then I bought fuel and headed home (70 miles). About half way home I got a "Low Fuel Pressure" message and a little while after that "Reduced Engine Power" along with the check engine light.
I pulled over to see if they did something like leave the drain open, thinking it might be sucking air. Of course it was dark and I could not see anything. However I did hear a buzzing sound and could feel a vibration when I touched the fuel line going into the top of engine filter.
While it is possible I got bad fuel, I suspect they did something wrong installing the filters. Even after cycling the fuel pump multiple times they had a hard time getting it started afterwards; I think they finally disconnected the top fuel line to bleed the air out.
I continued home and made it, but not sure what to do now; its 70 miles back to the dealer.
What is the most likely problem? Improper fuel filter installation or bad fuel?
Should I pull the filters in the morning see if there is something obvious like an out-of-place gasket? If so, top or bottom filter?
Is this a tow truck affair or should I drive 70 miles back to the dealer?
What the heck is the buzzing sound?
2016 F350 6.7; ccsrw, 22K on truck (zero issues previously). Stock other than titan fuel tank that was installed at 100 miles.
700 miles into todays trip, pulling trailer, snowing, in 4x4, tow/haul; pulled out to pass, got into it for a bit and got "reduced engine power" error, truck slowed, would not show boost on gauge, wouldn't rev over ~1900. CEL is on.
Pulled over, stopped, checked under/over and didn't find anything. Shut off truck, started back up, CEL is still on, but truck runs OK. Ran for another 20 miles or so and was OK for how I drove it (including boost showing on gauge). Not hot rodding, crappy road conditions (snow). Got on a big hill from dead start and got into it a bit, about 3K same error came on and she went back into limp mode. Same deal, stopped, shut off, back on, was able to keep going. Was only couple miles from motel at that point, so she is on break right now.
Of course I'm 400 miles from home and nowhere near a dealer. I have a code scanner, but nothing with me to pair it with (daughter has tablet with her, ha ha).
Should I keep going or find a dealer/tow/other? If she will keep running "normally" below 3K, then I can make it home as I don't need to horse it that bad on the roads I'll be on.
Truck has had fuel filters replaced on schedule, dealer has done all service work (oil, etc). Fuel filters were done 7500 miles ago.
This trip, was on third tank of fuel. Had just put in 30 gallons at last (big) truck stop about 15 miles before this issue happened, have 50 miles on this tank. That was 30 gallons into 50 gallon tank.
