Ford 6.0L Power Stroke Diesel :: Got Code P0683 When GPCM Off?

Had the GPCM off for the recent injector reseal job. Kid called me after school let out that it started like dog doo, has this code.

I am guessing something got chaffed or broke between the PCM and the controller.....I don't want to just throw a new controller at it.

How to test this? I am guessing there is a wire from the PCM to the controller that is not making the connection.

I noticed the code the other day, thought it was related to all the cranking perhaps. Reseated the two plugs, no joy.

Ford 6.7L Power Stroke Diesel :: F350 - Truck Shut Down While Going At About 25 MPH

I am getting ready to go on vacation this weekend with my f350 and I was driving today when suddenly the truck shut down while going at about 25 mph. I tried to start it and it just kept cranking. I got it started 5 mins later and it threw a P0069 code. I drove for about 2 more miles and it shut down again, and started right back up. I'm guessing map sensor? This was the last thing I needed to happen!

Ford 6.0L Power Stroke Diesel :: 2004 F350 Truck Will Not Start

A little background, this is an 04, f-350. It sis not start a week ago so I charged the batteries and it started, started fine this morning, (had not driven it for the week) Drove it to work, 35 miles, parked it, and it will not start.

I downloaded Torque and got a few numbers,

HPOP 1900 FMP 48V (repaired last summer) and FVP 11.5V.

Ran out of battery to surf more and look, so I am trying to figure out the app, and the issue with the truck. It seems to turn over good, until I ran the battery down, and the GP cycles normally, and the injector buzz seems good. Temp is in the 50's...

Ford 6.0L Power Stroke Diesel :: 2003 F350 Truck Revving Up Out Of No Where

So 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?

Ford 6.0L Power Stroke Diesel :: 2003 F350 - Truck Not Starting When At Operating Temp

The other day, I started having problems with the truck not starting when at operating temp. Went for a drive and stopped a a scenic overlook, and spent about 30 minutes taking pictures. Went back to the truck, and it wouldn't start. Outside temp was about 95 degrees.

I tried for about half an hour to start it, but all it would do is turn over. There was a work crew there with their heavy machinery, and I was able to borrow their starting fluid. One quick squirt into the intake, and it fired right up.

Although I do have an oil leak from the right valve cover, when I checked the oil, it was just off the full mark. The truck was parked on a slight angle with the driver side being about a foot higher than the passenger side.

Ford 6.0L Power Stroke Diesel :: 2004 F350 - Rear Of The Truck Sways When Going Down The Highway

04 f350 drw 2x4 ... I know this is a weird question, but i put 4 new tires on the rear of my truck and developed what i can describe as "loose body" symptoms. Most noticeable in going down the highway it feels like the rear of the truck sways and its hard to control and keep straight at times. Check tire pressures n front and rear suspension for broken springs or loose joints. Nothing looks broken or out of place. Prior to replacement truck drove straight n all was good. Also noticed steering wheel is now off center.

Ford 6.0L Power Stroke Diesel :: F350 - Speedo Won't Work When The Truck Goes Into Limp Mode

What the problem is with my F-350 6.0. I have an intermittent problem with my Speedo reading zero while I'm doing 70mph on the fwy. since the speedo won't work the truck goes into limp mode, the turbo will not function at optimum level. I have replaced the diff. sensor, the trani sensor, the a.b.s.sensors, the instrument cluster to a reman cluster. Then when I had a local mechanic plug a laptop dianostic program on it as he was running through the system inadvertently the radio cut out, so I found that who ever installed the after market stereo they cut a few wires to the harness, I went to the junk yard found the harness end and replaced the end. so with all that said and done no one knows what is causing this speedo not to work and limp mode. about 4 years ago the oil pump stopped working and ruined the turbo so the whole front end of that glorious 6.0 was rebuilt the problem started about a year after that.

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.

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.
