Ford 6.0L Power Stroke Diesel :: 2005 F350 - Rough Starts And Erratic Idle

A while back my 05' f350 6.0 was having rough starts and an erratic idle. It died coming up to a stop sign it started back up after 2 cranks and then it did that same on the way home. The next day leaving work it wouldn't start. I knew i had a couple injectors on the way out so i decided it was time to replace all 8 upon tearing it down i noticed my oil cooler was leaking so i figured it was time to rebuild that and finally do the egr delete that i had been wanting to do. well i put it all back together and got a no start.

The dash gauge on my oil pressure is reading normal when i cranked it so i went and bought a scangauge2 to read the icp its hitting 1500psi when i crank it. The ipr% is reading good. But my ficm main power is at 26v with the key on then it drop to 14v while cranking and eventually down to about 9v. Its never at the 48v that its suppose to be at. The scan gauge is also showing that my ficm sync=0. Would the sync be showing 0 since the ficm is bad? My batteries are fully charged and i have both of them on the charger while I am cranking it.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Engine Starts After Clicking Sound When Crank For Few Seconds

I am lost on what I need to do with my 2005 6.0. Last summer it started giving me trouble once in a while starting. I turn the key on and wait for the wait to start light to go out. When it goes out, turn the key and it starts, most of the time. Last summer I went to start it the same way, only it cranked and did not start. I turned the key off, back on and cycled the wait to start light again and turned to the start position, it started right up. Whenever it would act up I just turn the key off then back on and it starts right up. Usually on the second try, but lately it has taken 3 or more tries. I am not finding any real pattern to when it wont start.

When it does not start I can crank on the starter until the battery dies and it wont even think about starting. Turn the key off and back on, it will start.
Another thing I have noticed, when I crank the engine I can hear a clicking from under the hood right before it starts. I think it must have something to do with the injectors. I will crank the engine a few seconds, hear the clicking then it starts. If I don't hear the clicking it will not start, so when it doesn't want to start I also do not hear the clicking sound.

The other day I started it, drove 5 or 6 blocks and shut it off. After 20 minutes or so went to leave. I had to cycle the key 4 or 5 times off and back on before it decided to start. It is getting worse, doing it more frequently, and taking several times of key off and back on to get it going. Where should I start looking to find this problem?

Ford 6.0L Power Stroke Diesel :: 2004 F350 - Starts Very Reliably But Stalls Within 1 - 2 Seconds

I have a PS 6.0 in my '04F350 that starts very reliably but stalls within 1-2 seconds. Restarts after cranking for 5-30 seconds. This only occurs if the truck sits for more than 6 hours. The longer the truck sits, the longer it has to crank to restart. Also if the tank is full and the truck is parked pointing down hill this does not occur, if it is parked pointing up hill it occurs even with a full tank. Shows no codes. I've had several mechanics look at it and no one has been able to explain or propose a solution expect for wholesale replacement of parts. The symptoms indicate to me that air is getting into the fuel system but I'm not sure where to look.

Ford 6.0L Power Stroke Diesel :: 2003 F350 - No Power On Cold Start

I recently bought an 03 F350. I've noticed on cold starts that it has no power. After about 5 minutes it runs very well. I have not noticed any misfires or smoke and there are no codes thrown. Based on what I have read here, I assumed it was a FICM issue. I just got done testing it and it was at a solid 48v with 1 dip to 46 on engine crank. I'm baffled at this point. The truck literally has no other issues except low power for the first 5 minutes.

Ford 6.0L Power Stroke Diesel :: Long Crank Time And Starts After Sitting And Cold

The past couple of cold starts (not real cold mornings though) I have experienced long crank time to start. Once started she starts normally. No time to read but I'm getting a little worried that I'll get stuck somewhere. I'll check back with my phone when I get into an area with cel service.

Ford 6.0L Power Stroke Diesel :: F250 - Cold Starts Fine / Stalls Immediately After / No Throttle Low RPM

I'm having an issue with the truck not staying idle after cold start up. The truck will turn over and start right away (not even 2 second crank) but immediately dies. The throttle will not work at low RPM. When I start the truck, it will instantly rev high, the revs will drop low, it will try to compensate and rev high again, then it will immediately die.

If the RPMs are under under 2.5k, the truck will immediately stall and die. When I attempt to use the throttle under that RPM, it will not work. No matter how much I depress it, the engine will instantly cut and stall out. It will not attempt to deliver fuel. The only way I can get the truck started is if I rev the engine high and hold it. I need to hold the truck at 2.5k+ RPM for atleast 30 seconds. It generally takes me about 5 tries to finally get it running (mainly due to the throttle immediately cutting out and I have to 'catch' and hold it.) After that, there is no sign or issue. The truck will start immediately back up after it's been running for a couple minutes.

CEL: MAP sensor (0069?) -- Sensor is spotless. Harness looks fine. I replaced the injectors, both batteries, and the alternator this summer. It doesn't sound to be any these either as the truck sounds extremely healthy and immediately turns over.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Lag Off Idle For About A Second Every Once In A While

Well, after getting the bed back on my '05 F350, I have been driving it on the road for a few days, but now I have a new problem.

Every once in awhile I get lag off idle for about a second, then the turbo spools and everything is fine. Other times, I step on the accelerator a bit from a stop, and the truck acts like its going to die for a moment, a puff of black smoke, and then the turbo spools and all is back to normal. It a combination of these two problems happens about 3-5 times out of 50 stops a day.

I have a scanguage and everything looks normal and I never get any codes when I check.

2005 F 350 6.0

124000 miles. Drove the truck on a long road trip Saturday ran great. Didn't touch it Sunday. Went out Monday morning and it wouldn't start I noticed the fuel gauge said empty and the low fuel light was on. I knew there was plenty of diesel still in the tank but I still went and bought 5 gal and dumped in it fuel gauge then read over half full but still won't start. A buddy who's a mechanic swung by sprayed starter fluid in it fired right up then died he said I need a new fuel pump. I have been reading the forums. I just want to make sure is he right?

Ford 6.0L Power Stroke Diesel :: 2004 F350 - Intermittent Loss Of Power / Stall Or Stumble When Engine Is Cold

I just bought a 2004 F350 6.0 cclb 6 speed with 260k on it. The previous owner seemed to have taken good care of the truck. It is basically stock with the exception of the blue spring mod, and a sinister diesel coolant filter. Anyways, I brought the truck home and it ran great. Now I have an issue that needs to be addressed.

The issue: I am experiencing a intermittent loss of power, stall, or stumble when engine is cold. After sitting all night the truck will start fine and idle fine. But when I try to accelerate and bring engine RPM up the engine will stumble and lose all throttle response, when this happens the WTS and WIF light flash. Sometimes it just stumbles, sometimes the truck will actually die and then restart. The issue seems to go away after the engine has reached operating temp.

I did some research on the issue and it seems there is actually a TSB out from ford for this issue. It explains that some 2003-2004 6.0's might have wiring harness chaffing issues. This is what the issue I am having seems like to me (shorting harness). I looked up codes on the truck and there is an active code (#8 glow plug circuit fault). I did a short visual inspection of harness and didn't see anything out of the ordinary. But i wonder if it would be worth changing both sides of the glow plug harness?

Ford 6.0L Power Stroke Diesel :: 2007 F350 DRW - Cold Start Hesitation No DTC / CEL

Recently I replaced the unison ring on my turbo, EBP sensor and cleaned carbon out EBP tube/upper part of motor. After doing so she seemed to run fine but not like I remember when I first got her. Plenty of power but ever so slightly off, only an owner would notice. Few weeks later she hesitates a little bit while she's cold in the morning. I let her run 3-5 minutes b4 actually driving but as u know it's a little while to get up to operating temp. Temps seem OK 190-200 EOT/ECT. Fresh oil/filter, air filter, coolant, EGR was cleaned out a little while back and EGR valve replaced 25k ago. I'm not sure where to look at this point...the motor has about 30k on it.

Ford 6.0L Power Stroke Diesel :: 2006 F350 - Lot Of Smoke On Cold Start

I have a 2006 F350 6.0 diesel with 110K miles. it takes me about 10 tries to get the engine to start. When it finally starts there is a lot of smoke and engine runs really bad. This isn't the case if I have the engine warmer plugged in. After warm up the engine runs pretty good.

My engine light comes on sometimes and will go out other times. I have tried sever attempts at adding injector cleaner with no results. Am weary about taking it to Ford for an analysis. Where to start with repairs? I did take it to Orielly auto and had the engine checked on their scanner. Approximately two pages of possible repairs come up.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Hard / No Start - Low Power

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.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - No Power To Move

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didn't have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines, harness, pump, sending unit , tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.

So I took that stuff to the garage had them swap it out and now they said come get the truck they won't work on it anymore that now it needs 3 injectors and they won't touch it with aftermarket fuel system on it. So i go to drive it home and it starts but runs rough and u can hold it to the floor and it won't budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Hesitates / Low Power Driving / Idle

I have a 2005 F-350 Lariat, FX4, CrewCab, with an 8ft Bed if any of that matters. Currently sitting at 191,000 miles and 4,500 Engine Hours I just started running into some issues that I cannot figure out. To start with here is a list of all the mods and prior maintenance that I've done to my truck over that last 6+ years that I've owned it.

I purchased the truck in 2010 and had no issues whatsoever for the first 3 years.....then it all started. While pulling a camper home from vacation "still bone stock" the truck overheated and by the time I realized it it was to late. I ended up blowing a head gasket cracking a head and blowing a hole in my coolant reservoir from the heat & compression of the engine in the coolant system. So to the shop it went.

All of this was done at the same time at just under 4,000 engine hours:

1) Both heads were sent out to be pressure tested "which is where the crack was found", so 1 replacement head and the other trued up and tested by the machine shop
2) All 8 injectors replaced with Airtex/Wells New/Reman
3) ARP Head Studs
4) BPD EGR Cooler
5) New Stock Coolant Reservoir
6) New Stock Oil Cooler
7) Motorcraft Coolant & Oil/Oil Filter Change
8) New Serpentine Belt

After getting the truck back I installed some upgrades that I had wanted but didn't want to do until I had head studs. 4" Turbo back Diamond Eye Performance exhaust, Bully Dog GT Tuner with an EGT Pyro, coolant changed to Caterpillar ELC, Sinister Diesel coolant filtration system, new Optima batteries "I hated them",

Forward a year with no problems I had a crank but no start. I ended up having a bad IPR. A buddy rebuilt the turbo since I had it out and it was leaking. He apparently did something wrong because it took its own life sometime after. So a brand new stock Garrett Turbo with a Wicked Wheel 2 & I changed the IPR "don't remember the brand." Also replaced the factory paper air filter with a cleanable one from AFE that fits in the factory cold air intake.

Little more time and I started to have some overheating issues again, luckily the Bully Dog was monitoring and I had alerts set up so I caught it way before it caused any serious damage. Turned out the fan clutch wasn't working. So I replaced the Water Pump with one from dieselsite.com that has a steel impeller, also replaced the computer controlled fan clutch with a 7.3L mechanical fan clutch and an adapter from BPD.

After that the batteries I hated were replaced. I installed Oddssey Extreme 950CCA ones, a new 185A alternator from FICMRepair.com as well as the complete battery wiring interconnect kit. Did the blue spring upgrade. Replaced my FICM with the BPD 6 phase at 54V setting. Also I changed my starter to an 6.4L Ultima one from O'Reily Auto to bring me up from that slow crank of the 6.0L at about 150RPM to the 225RPM of the 6.4L.

So now on to the current issue. This has happened in the last month and may be related to the issue. I had some small coolant leaks and wanted them fixed. Pressure tested the system & found the radiator and timing cover gasket leaking. I installed a new stock radiator and lower radiator hose. Had the shop do the gasket and a serpentine belt due to cleaners being all over it. During replacement of the timing cover gasket my mechanic found that the LPOP gears had some damage as if something had be in there at one time. Not sever damage just minor. LPOP replaced with brand new one from Ford.

After I got the truck back it was fine for 2 weeks, no leaks or any problems whatsoever. Then I noticed a hesitation as I was leaving work at idle. You could see the RPM's moving up and down by about 50 as it sat there at idle. It got really bad and eventually stalled on me. It fired right back up and ran fine after. I was thinking water in the fuel or just maybe old fuel because it was kinda old and I was at 1/4 of a tank. I went and filled up and it ran great all the way home. Day or so later same thing. At idle you can see the RPM fluctuating and while driving it feels like it has no power at times then it goes away and runs fine. So I changed both fuel filter with Motorcraft ones and put in a new oil filter. It is the Wix brand but I've be running it for years with no issues, one was also in it way before this issues started. The oil has about 2,000 miles on it currently. I verified fuel pressure at idle to be at 70PSI. I tried unplugging the ICP at idle with no change in the hesitation. So I plugged in my SG2 and started to see if I could see anything out of the ordinary.

OAT - 60 Degrees F
KOEO Engine Cold - FMP - 54.5V, ICV - 0.25V, ICP - 0, IPR - 14.9
KOER Engine Warm - FMP - 54.5V, ICV - 0.82V, ICP - 576, IPR - 23.5
Cruise at 40MPH - FMP - 54.5V, ICV - 1.14V, ICP - 965, IPR - 32.9
Cruise at 50MPH - FMP - 54.5V, ICV - 1.42V, ICP - 1,190, IPR - 38.0
Cruise at 60MPH - FMP - 54.5V, ICV - 1.27V, ICP - 1,143, IPR - 37.2

While driving this issue comes and goes very randomly. The only parameter I notice changing alot is the IPR. It jumps around a lot and sometimes it will go to 85. I know that this isn't a good thing so I am going to change the IPR later today or tomorrow. I already had a brand new Motorcraft one to put in, plus at the very least I want to look at the screen. I had read somewhere that there could be air in the oil system and that if you run at a high RPM it can remove this air. I never seen any bubbles or anything on the dipstick. My brother ran the truck for me at 3,000RPM for 5 minutes. No hesitation during the test but he didn't have the SG2 plugged in so I don't know the parameters during the test. I thought that it worked but then it came back after a few miles of driving. The above parameters are from this mornings drive home from work.
