6.0L revving to extreme high RPMs and kill? Blow turbo was replace, fired right up but upon pulling it out while giving it lower RPMS (2000) engine over revved and killed - Now crank but no start. Checked everything. Removed valve covers, checked injectors, great fuel pressure.
View 14 RepliesIn the beginning of January I bought a 2004 F-450 6.0 with 186k miles (not sure if its been clocked back).
Since I bought the truck I have had only 2 issues that are odd. One is a hot no start that is very sporadic (its happened 5 or 6 times). I know it needs 500 psi min to crank and when that happens it gets to around 350psi. Because Im afraid of issues I did a oil change the day after I bought it did a road trip of 2500 miles (with no issues) and did a oil change again. All with motorcraft filters, lucas oil stabilizer and I use a little of diesel kleen or lucas injector cleaner every time I fuel up. I was told never go below half a tank so I follow that rule.
The second is a small oil leak from the passenger side. BUT it only happens when the truck sits for 3 or 4 days unused. During my road trip, not one drop. I used it on the weekend not one drop, but since its my 3rd vehicle I park it Sat or Sunday and by Wednesday Ill see the size of silver dollar, I cant seem to find it.
Also it has a egr delete but the heads have not been done, and I want to put a tuner. Would that be ok? I dont drive hard. As a example on my road trip I NEVER went past 70mph(with my wife saying I drive slow) and I averaged around 15mpg. I would like to get more mpg.
2004 f450 with 6.0. Was driving down the road when it started losing power like it was starving for fuel. It carried on for about a mile then died and will not start. No codes at all and we put a new fuel pump on but still wont start. Put a rag with gas in the air box and will run but rough.
View 6 RepliesTwo days ago, I was driving on a North GA steep, windy, mountain road in my 2002 v6 4.0 Ranger. All of a sudden, i started revving real high (about 4000rpms) and getting no power (20mph). I pulled over immediately and transmission fluid was pouring, by the quart, out of my truck. I didnt get to look exactly where it was coming from, since i backed away once i saw a small flame coming from the leak. i then called a tow truck (assuming it was a seal or a hose break) and had it towed to my house.
I started investigating the possible problems and didn't really see anything noticeable under the truck (not that I was expecting to). So what I did was put three quarts of transmission fluid in the dipstick hole and put in gear to see if I could spot a leak. nothing. then I drove it around the block to get it warmed up and put a little pressure on the transmission by driving up a semi-steep hill to see if that would spark the leak again. still no sign of the a leak.
And finally, when I went to go check the dipstick after my test drive, it read to be above the cross hatched area, hence being overfull. What my next step should be?
I literally just got this truck 1 week ago. '05 6.0 F250. I have read numerous other threads and have not found an answer. I will start from the beginning.
I was driving on the hwy and once the engine is hot and I am over 55mph the truck feels like it wants to stall. The rpms drop and come right back up. Its like a 'hiccup'. If it starts to act up and I pull over it remains at idle and not stall. Once i get back on the hwy IF I go over 55mph the truck will stall and I will not be able to start until cool.
After doing some reading through the forums I replaced the IPR on the HPOP.
I tested the high pressure oil system. I took off the valve covers and tested both the right and left side individually, with the IPR valve open and close; cannot find a leak.
I took the fitting off of the top of the HPOP and tested with air there as well. I only hear air out of the weep hole in the back behind the gear on the pump.
I took the oil pump off and charged the branch tube with air, no leaks.
I checked all the dummy plugs. They have been already replaced with the upgraded ones and the orings all looked good.
I took the upper half of the standpipes out - look good, orings looked good. I was unable to get the lower half of the standpipe out on the passenger side due to the air box and the driver side only the top half came out when unscrewed from the oil rail.
I put it all back together with 2 new batteries.
I started it, (started cold), drove it 25 miles and it stalled, let it cool down and it started. Drove it 20 more miles and I pulled into a parking lot and I shut it off, and it started right back up 3 times. When it shut it off on the highway I unplugged the ICP sensor and it did NOT start.
It runs fine until I go over 55mph then I am getting the same stall issue. I can drive it around under 50mph and have no issues. I drove it under 50mph and shut it off a total of 3 times and it started back up no problem. If I drive it over 55mph rpm gauge drops and then comes right back up and IF it stalls I cannot start until it cools. Once it stalls out, If I try to crank on it, my IPR is 84.8% IPC - 99-120.
I am using a Scanguage II at idle:
ICP - 18.5
IPR - 585
FMP - 47.5
My FICM Voltage stays between 12.5 - 13.0 while running.
I have 2003 f250 6.0, had the turbo rebuilt and I put it back in, my turbo is whistling but I'm also getting a humming noise kinda sounds like a when u down shift at high rpm's idk what's going on, I try and power break as well to build up boost and the tires do not even spin...
View 4 RepliesSo I just purchased my first diesel a couple weeks ago (2003 f250 Lariat). I love it! However, I'm having concerns about my turbo whistle on it. At idle and while in higher RPMs is sounds ridiculously loud (even at 0 PSI in the boost). I've been doing my research on it and I know the 03's have the loudest sounding turbos because they have less vanes than the later models. I know without a video it's going to be hard to diagnose, but I am wondering if a loose boot would cause a turbo whining sound through the exhaust? I have yet to hear ANY other diesel in person that has a turbo whine as loud as mine.
View 14 RepliesI am noticing a extreme lag in acceleration. When taking off from a stop it lags really bad then acts like I floored it. My FMP is 48 sometimes dropping to 47.5. FLP is 13 sometimes dropping to 11.5 during starting. Occasionally it doesn't want to start, like its not getting fuel. New batteries 3 months ago. Also has blue spring. Its a 2005 thats never had anything done to the FICM, so its kind of old to begin with. I read in another thread that the FICM relay should be replaced occasionally, so may that could be contributing to some of my probs.
View 14 RepliesMy friend has an F450 with the 6.0, and discovered fuel in his coolant. I have the 7.3 in my truck, and know next to nothing about the 6.0. Can bad Injector sleeves cause this ? Is that the same as "seats" ? I am not up on my terminology. He thinks he needs new heads for his truck, but I don't agree.
View 6 RepliesI have an F450 with a 6.0 turbo diesel with 267000 miles std trans. 4wd and just bought it a few weeks ago. When the engine is cold, the truck runs fine but after driving for 15 minutes, I loose power in 3rd, 4th, and 5th gear. The gauge for the turbo drops from 20 down to 5 and the truck starts blowing black smoke. This starts at 1500 rpms and stops when I am past 2200 rpms.
Before 1600 rpms and after 2200 rpms, the truck has lots of power but withing those ranges, the truck has almost no power at all. When I first got the truck, the problem didn't start until I was up to 1800 rpms. No codes showing up either. I had the truck serviced by a diesel mechanic and the filters replaced using Ford parts. Problem persists and only exists when the engine is warm.
I am on the market for a 2015 Ford F350 with an 11' Royal utility body on the back for my electrical contracting business.
Ford have come back to me and said I need a F450 as I am going with the supercab, the F350 can not handle the 11' utility body.
I have head that the F450 can cost more in Insurance and use more diesel. I contacted my insurance company and they said it wouldn't change to much, this is in CA.
Is there any differences between the F350 and F450 apart from the rear axle and larger brakes. Also if there a major difference in MPG.
I currently have a Ford F150 Limited and love it!
I have a 2015 Ford F-450 6.7L Diesel with a 12 foot flatbed on it that I use for my power washing business. The air conditioner sometimes won't work when I first drive it in the morning. After I make a few stops and turn the engine on/off a few times it will all of the sudden start working again.
This happens about 2 or 3 times a month and I don't have time to have it sit at Ford so they can duplicate the problem. It's going in for it's 60,000 mile service in the morning anyways so I'll still have the dealer look at it. What might be causing this?

I have a 2012 ford f 450 which has the standard Rancho shocks,the problem is the ride is very rough and the truck bounces when the road gets a little bit undulating. How did you fix it.
View 8 RepliesI have a 2011 f-450 6.7 - truck has 70K miles. The other day I was driving and the message said "Cleaning exhaust filter ". I usually keep it running a little to finish. Then shorty after a warning message came on which said "800 Miles to Exhaust fluid empty". So I went to fill tank and it was FULL. Now the warning keeps showing up each time I start the engine. It now says 300 miles to empty. I'm afraid it's going to go into limp mode even though the exhaust fluid tank is full.
View 14 Replies2006 F450 6.0 that I've owned since new. It has had 2 injectors replaced previously, EGR cooler with BPD, and a few other problem parts. As it is getting older, I have recently noticed it runs like absolute dog crap when it is cold. It can't even reasonably accelerate onto the hwy when cold. Once it is up to operating temp, it runs better. It still does not pull like it did when it was new and under 50k miles...but it is at least driveable once warm. I need to do some heavy trailer towing soon and need to get this thing back to accelerating good. What should I be looking at first for the horrible running condition when cold?
View 14 RepliesI have a 2012 Ford F 450 turbo diesel dual wheel truck,my problem is an engine light came up on the instrument panel so i hooked up my scangauge and found the code P20BA I went further into the diagnostics of the scangauge and found nothing,i cleared the code and drove down the road and the light came back on could the sensor be faulty and if so does any body know where the sensor is located.

View 7 RepliesI have a 2011 f450 that I just bought and it has the plastic oil pan. I see that the newer 6.7 have the metal lower oil pan. Is there a good reason to change over to the metal pan? Is the 1/4 turn drain plug the problem?
View 13 RepliesI've been getting a surge or revs when getting up to cruising speed before it drops into overdrive or or a constant speed. Happens around 1800-2200 rpm before up shifting to the next gear. More noticeable if under a load or going up a grade when it will hold gear longer before shifting. Only thing I can think of that would be related is the truck does lack some power on a cold start for the first couple miles before getting up to temp. I've cleaned the ebp sensor and it appears to be working correctly, reading within .1-.2 of BAR/MAP key one engine off. VGT solenoid is clean but have no real way to tell if it's working correctly. Other values icp/ipr temps fluid levels appear to be correct. Just changed the oil and it continues, changed the transmission oil and filter about 3000 miles ago. I've had this going on for about 1000. Started about the same time I changed tunes to PHP. They haven't been able to find anything in the tuning yet that could be causing this or if it is just making it show up now.
View 14 RepliesSo I'm having a problem with my truck revving up out of no where. Happens more when I'm driving. It only shoots up a little bit but sometimes goes up 1000 more rmps. Happens for a quick second then stops and does it again. I've had the ckp replaced and it has an egr delete. Other than that it's stock. I got home and let it idle for a minute. The rpms fluttered up and down in small increments and almost stalled out. What is causing this?
View 4 RepliesI own a 2003 Ford F-450 Superduty Chassis w/Utility Body. Owned it for the last 2-1/2 years . So far, the only things needing replacement were an Alternator, FICM, and routine oil and transmission fluid as well as filters.
This past week the truck started lurching while in traffic. I brought it back to the shop and put the scanner on it, and found codes for #1,#3,#5 injectors imbalance and no circuit to the fan motor. Did some research and found low oil and/or dirty oil could affect the injectors, I changed the oil and all filters also removed the EGR and cleaned it too.
I started the truck ran it, stopped, and restarted and let it run for a few. I cleared the codes and did another test. The only code that came up was the Cooling fan P0528 again. I let the truck run. All of a sudden the truck revved up and I could hear the turbo kick in and the engine seemed to take a life of it's own. I did another round with the scanned and found codes for Cruise Control popping up P0565 through p0569 and the p0528 again along with a p1000.
My truck is not equipped with cruise control, but apparently that is what might be making the engine surge. What do I do? What this might be???
