Ford 6.0L Power Stroke Diesel :: 2005 Won't Start - Code P0401 And P0672 Shows Up?
Aug 25, 2015
2005 PSD Ex. 4x4.
Drove it a few nights ago and it felt really gutless. Next morning, no start. Well, it tried, but it sounded like it was run out of fuel (had half a tank)and I turned it off. Changed both fuel filters, key on / key off to purge system about 2 dozen times. Still no start.
I have all eight injectors with "injector Circuit Low" code, a P0401 - Exhaust Gas ReCir Flow Insufficient Detected, and P0672 - Glow Plug #2 (which it has had for a few months).
I thought with all of the injectors, it might be the FICM, checked the FICM voltage with Torque during a start and it showed 47V the whole time.
Harness? I did not think running with the glow plug error would be a big deal especially during the summer in So Cal.

I have a 2005 f350 6.0 power stroke. I had a crank no start when hot issue. I bought an obd scanner with the torque app. IPR was at 85%. ICP pressure was low. I got the IPR out and bought a new screen because it was clogged. Upon putting in I broke the injector female side plastic connection.I bought the injector connector piece and installed it. After putting everything back together it starts but runs very rough,low power. The IPR was fixed. ICP,ipr and ficm are at good levels now.
IPR=14.7%-30%
Fcim sync=1.0
Fcim voltage=48.5
ICP pressure (idle)650-850psi
My fault codes are:
P0672 (glowplug)
P0674 (glowplug)
P0678 (glowplug).
Why it would be running/idle rough?

After installing the Sinister Diesel EGR Cooler, a new stock turbo, new EGR valve, and new #7 and #8 injectors, I am still getting the P0401 code. Each of those items needed to be replaced, by the way.
The motor runs fine; it just continues to throw the code. It has been to the dealer, and they can't figure it out. Is there a diagnostic procedure I can follow to hunt this elusive problem down?

So I'm about to do the oil and EGR coolers on my 6.0. At one point, or currently, my EGR cooler was leaking, so I've got that gooey residue in the intake, at least around the EGR valve. No dry carbon residue. I wondering what is the best way to clean the intake out, if at all. I have to assume there's some clogging in there, especially since I've had the P0401 code for a while. I just wanted to get this done right once, so I'm not coming back to it again any time soon....

My 2011 has 62k miles and has been throwing P0401 codes, which results in losing power. I assume the EGR cooler is clogged. So I went to the dealership to see if it's covered, and was told there's no warranty coverage.
I would rather blockoff the EGR cooler than repair it. I would also like the extra performance from a tuner like the MiniMaxx. I do prefer the stock exhaust and not real excited about the drone/smell that comes with deleted DPF.
Will I have issues if it's tuned with the EGR blocked off, and stock exhaust? Or am I better off doing a full delete at this point?

Near the end of a 5 hour drive on Christmas day my check engine light came on. I read the code: P0401. I got it into the dealer this week and was told it was a blocked EGR cooler. The truck has 66k miles. Lucky for me, I have the extended warranty! They replaced a "tube assembly". I sure hope this is not something that is going to repeat. I would hate to pay for this repair in the future. They had the truck 2 days. Is this a common problem or am I just "lucky"?

The truck in question is a 2004 6.0L Excursion, stock original turbo, no tunes, and EGR cooler delete done 1 year ago. Scanned for codes and none were found except for EGR insufficient flow P0401 code which is due to the EGR cooler delete.
Upon startup (no issues there) the VGT reads 67-70, now once the truck goes to high idle to warm up (1150 or so RPM) the VGT slowing climbs to 85 and stays there. If I blimp the throttle or step on the brake it goes back to 67-70 at normal idle. This has been happening for a few months now on a regular basis. I have checked the MAP, BARO, and EBP readings at KOEO and they are all within 0.6 of each other (14.4-15.0). The EBP tube was checked and cleaned (no buildup present)..

I just picked up a 2011 Ford F350 about 8 months ago. I have had troubles with the check engine light coming and going. Now it's been on for good with loss of power. I have had the codes read and they came up as the p0401 and a code about the def heater. I can not remember that code off the top of my head. After some searching I have found a video about the def heater but nothing about the Egr cooler/valve. Is there anything out there about how to clean and remove the the cooler as I will be needing to do repairs myself as the truck has no warranty.

I have a 2005 F550 with a 6.0. Recently I have had issues with a long crank before starting at times but once it started there were no issues driving. Yesterday it started up in the morning, made a few stops then it wouldn't start at all. Cranked strong but no start. Had it towed back, sat for an hour or two now it starts again. Put a gauge on it and all readings are good. Did have a P2285 code which the ICP sensor. I do suspect there could be an issue with the egr cooler as it needs coolant occasionally. Could that have anything to do with the no start? Truck has started fine today. Why start sometimes then not?

My 2012 got it's first "500 miles to empty...." DEF alarm yesterday. I added 2.5 gallons and the same alarm keeps showing up each time I start the engine. Is there some kind of other reset required? Do I need to fill the tank up completely to reset it? I'm concerned the engine will shut down after 500 miles even though the DEF tank is about 1/2 full.

Getting DTC P0401 on my 2011 with 92K miles. First time I got the CEL, we were on vacation, so I read the code, took a screen shot, then cleared it. Called my normal dealer, setup an appt, verified that they thought the truck was safe to drive. Coming home from vacation, I was pulling the TT in my sig, and noticed significant loss of power on hills that I have pulled many times before that I couldnt even hold 55 on now. Transmission dropped into 4th a couple times, on hills that it would sometimes stay in 6th, or at most drop to 5th.
CEL stayed off for a week , and came back on again. The funny thing is that after a day or 2, the CEL went back out on its own. I read the codes the P0401 is still there as a stored code(I did not clear this time). Around town the truck drives fine, the only thing I noticed was the decrease in power when towing. Truck is at the dealer now. TECH "isn't convinced" yet that there is a problem. He is not finished diagnosing yet, and I am sure that he has specific tests to run, but I am starting to fear that I will be getting the call to come get my truck.

2012 F350 with 52,XXX miles and the P0401 keeps coming back with no degree of consistency, could be an hour later could be a week before it pops back up. just in th epast 4 days i have replaced the air filter (FOMOCO) and still same thing. there is no change in performance, just dont have that warm and fuzzy feeling since im about to head out to Colorado for 10 days with 5000 lbs of toys in tow.
btw, P0401 SAYS INSUFFICIENT PRESSURE FOR EGR
PURE STOCK, NO TUNING

Been working on a 2005 6.0 with 218kish miles on it. When I got the truck it had a contribution 2 code stored, no check engine light, just could see the code on the code reader.
Truck idled like crap, lacked power, so I replaced the injector. Truck improved but still had a miss, this time it had a stored code of injector 6.
Ordered another injector, got it installed today. Fired the truck up, ran perfectly, drove it around, absolutely 0 issues ran like a dream. Parked it for a few minutes before starting it again to wash it. Rough idle, not horrible, not noticeable. Cylinder 6 contribution code stored again, no check engine light.
So I drove it, I drove the hell out of it for about 15 minutes with the AC at full blast, WOT, etc etc. By the time I was done, truck was back to running smoothly.
Just walked outside after dinner to see if it would still perform well, or if it would idle poorly again, sure enough, 6 contribution, rough idle.
I just changed fuel filters with OEM, air filter is new. I just cleaned the EGR valve- although maybe it's not clean enough?? Oil change is tomorrow (had to wait for the filter to get shipped in).
I'm at a little bit of a loss on how to cure this miss, unless it's possibly an oil pressure issue from bad/old oil causing it?

I'm having a little trouble with my 05 Excursion 6.0L .... We took off camping the other day pulling our 30' camper and the engine light came on pretty much as soon as we hit the highways. I checked my Dash boss and it came up as P0299 under boost condition. The truck never skipped a beat. The boost gauge never dropped and it seemed to have lots of power. Actually I've noticed too much boost while pulling. It's climbed up to 36psi before and was still climbing when I backed off the throttle. I'm thinking the turbo is fine but not sure what to check next.

2005 f350 6.0, parked in my shop and the batteries were dead after 2 weeks on vacation, (I left a few items plugged into 12vdc ports charging) charged it up and started right up. Next day cruising down the road about 75 the wrench icon showed up, strange. I reviewed my scan gauge and only thing not correct was my boost, it was 20lbs plus, idles at 14lbs. dash gauge appears normal.
Next morning I turned on the key, turned on my scan gauge engine is not running and the reading show 14.4lbs on my scan gauge. so..... adding the 14.4 to the scan gauge reading thru the drive cycle. so my computer thinks it is seeing 20-30 boost during acceleration. A bad sensor......... but don't know which one.

I have a P0401 code that just fired today. I tried to clear the code, but it came right back on the drive home. There are no drivability symptoms so far; just the CEL.
It looks like the DPFE sensor is part of the EGR valve on this model. Do the 401 code usually means that the EGR needs to be changed, or if there are other common causes of this code that I need to check? The DPFE sensor fixed the same issue on my Escape, but that was an easy $34 and 30 seconds repair. Looking for some 2004+ year owners' experience (I guess 2002 and 2003 models had the DPFE?).

My 05 F350 will not start hot, occasionally stalls when hot as well. Starts immediately when cold and runs smooth as silk. Truck has 138k miles on it, I bought it studded and deleted, running 5w40 Rotella T6 with Archoil. Some history on the issue: Started out with a rough idle, found low FICM voltage along with a bad battery. Replaced both batteries and FICM, problem fixed. Soon after developed a misfire with a cyl 5 imbalance and injector code, replaced all 8 injectors which fixed that issue.
About 2 months ago I had a no start problem, turned out to be a bad ICP, replaced that and the harness and was all good for about 3 weeks. That's when it started becoming hard to start when the motor was warm, and then no start at all when hot and would stall occasionally at idle, wait an hour and it'll fire right up!
Ran the air leak test, found a leak on the right bank standpipe, replaced the dummy plugs and standpipes, no start still remained. Went on to replace the IPR and STC fitting which didn't work either. Now it throws a P2285 code, low ICP. Ran the air test again and I don't hear any leaks. HPOP seemed to have good compression turning by hand.

Long story behind it but finally got my scanner working right and checked the suggested systems for p2290.
IPR was 77+ on start up dropped to around 31 at idle
FMP is in the 46.5 to 47.5 range
SYC was at 1 and occasionally at 1.5
ICP was at 550-650 during startup and quickly ramped up to 1150 then settled into around 850 at idle.
The only thing that I'm not sure of is the IPR being 31 at idle, is that what it should be. The others I think are within normal operating parameters.
The truck starts but has no power. Can barely go up a slight hill on my street. Seems like it's going to be fine but as soon as I apply a little gas it just falls off.

Don't know where to start so I'll ramble!
2005 f350 with the 6.0. Crew Cab, 8' box, 4x4 with DRW. I use it only take the boat to the launch 5 minutes away once in a while and to pull car trailers every other week. Majority of driving is on the highway and average trip is about 300 miles. Low power and now no start.
No codes. I do have a scan Gauge and can provide data.
Was running this week, but has had a lack of power for some time. I had put 2 new injectors in last summer. Also updated dummy and stand pipes. Blue spring. Also new IPR at the time.
Ficm board was replaced in March.
New injector harness last year. New Glow plug harness last year.
Coolant level is fine and none being lost.
CAC hoses appear fine, no cracks.
No boost. But newer MAP sensor, hose not cracked or plugged and nipple on intake is clear. Put the MAP sensor last year and it didn't make a difference.
Turbo was rebuilt 2 years ago.
IPR has to hit close to 80 before boost hits 12-15. But it takes a while to get there.
Now won't start.
Yesterday am it was about 30 farenheit and no start. Last year would start no problem.
Batteries are fine. tested.
Engine fires within 3 seconds, but doesn't want to run.
ICP is above 500. climbs as I turn over.
Fires only in first few seconds and then nothing while I keep cranking it. it is cranking fast enough though.
Now...I see IPR will hit 84.7% and then 14.8%. Not good!
When running it sits in between.
FICm voltage is 48.5 key one and 47.5 when cranking.
Wondering if possibly IPR screen is plugged? Or would CKS or CPS cause issues? I recall reading about pulling one of them and cleaning rust off of it? Also...should mention, no EGR reading on scan gauge..never was either. I had checked and cleaned egr valve before. it was clean when I pulled it and not sticking.
Intake had been cleaned 2years ago. Also, on occasion, while pulling up hill, I would get power! Black smoke and it would race up a hill like it's supposed. Then it would go back to no power.
Also...if I pull the MAP hose from the intake nipple, should I feel suction from the intake? There doesn't appear to be any air coming or going from the nipple.

I have 2005 f350 with 365000 km on it I have it for one year and don't have a problem till last week. I was pulling van on dolly uphill and sadden lost pover, so I stopped and check oil leaks ,transmission .... But everything looks ok in couple minutes start engine and go home (10 km). Change fuel filters trans filter, looked good for 50km and star losing power again and doesn't want start. So I skan and its show me next numbers.
Key on engine off
Ipr-15%
Icp-0psi
Icp-.26v
Ficm main power-47.8
Ficm logistics power-14.5
Ficm sync is good
Engine crank
Ipr-85%
Ficm main power-48.0
Ficm logistics-12.5
Icp- 625psi
Icp-.77v-1v
So what I have to do?

I was working out here on a site north of OKC and the truck has been running great all day. I shut it off to do the job and 20 mins later it will not start. I pulled the codes P2291 low ICP. One thing I noticed is that I cant hear the lift pump running when I turn the key on. I even drained the bowl on it and still can't hear anything. So I'm thinking bad lift pump or something.
