Ford 6.7L Power Stroke Diesel :: No Crank / Lost Communication To PCM
So my 6.7 left me hanging the other day, went to start nothing. Towed it into town started. Went to start it couple days later nothing. Jump the plug by right battery starter turns. When key is turned to run no glow plug light, no fuel pump prime. Tested ignition switch good. Tried 2 new Batteries nothing. got power on fuse 52, continuity from fuse 52 to pcm connector. Fuse 49 and 50 also have power. Took all 3 connectors at pcm out and blowed air through and sprayed W.D nothing. Even tried with connector on transmission. Scan tool will not communicate with pcm.
Codes after cleared:
instrument cluster:
uo100 lost communication to pcm
u300a-64 ignition switch...

Ford 6.7L Power Stroke Diesel :: Communication Failure With All Modules
Having issues with the instrument cluster and lost communication trouble codes. My truck has been having issues and it loses comm with all the modules. All the warming lights the truck has come up on the LED screen in the dash and if I turn it off it will not start. Most recently my traction control light stays on and my tranny is locked into 5th gear. I have park, reverse & 5th gear. Most recent DTC's are lost come with TCM & ABS control module. It seems to be getting more consistent but was very intermittent. Spent a week at ford with no progress. Truck wont start for a full day and then will start the next morning? When its bugging out it wont even prime the fuel system of turn over. Cab was off last fall to install SPE diesel STG 2 short block, Industrial compound turbo kit & water/meth kit. truck has been amazing and insane power until recent electrical/computer issues. When truck is bugging out tuner will not communicate with the truck and cannot read codes or remove programmer.

Couple of weeks ago, the display in the instrument panel displayed a large orange wrench. No accompanying text or chimes, just the damn wrench. Checked for codes, nothing out of the ordinary (I occasionally get communication codes, but they usually show up when I do not wait to start). Long story short, the damn thing showed up one more time the same day, then never again.

So my dog was riding in the back seat of my 2011 SD with covers when he suddenly went nuts over seeing a bunch of Prong Horn running along the road and jumping a fence. It was pretty cool to see, but he scratched the heck out of the arm rests.
How the scratched dark grey color can be repaired? Everything about the truck has remained pretty pristine inside and out, but this is really bothering me and I can find no information.
I'd even consider recovering all 4 with some sort of kit, if available like they have for some dashes and interiors.

I have a 04 F30 4x4 with a sick 6.0 power stroke. It has 230k on the mileage and ran good. I was driving at speed when she started missing like it had lost an injector and loosing power. The RPM's dropped under 1000 so I had to pull over off the highway. When i pulled over and put it in park it shutoff. Tried several times to get to start but after 10 minutes it started up. I drove about 2 miles and it started the same process. This went on 2 more times before I was able to finally limp home the 40 miles.
It never shut off again but ran very poorly. I put a new valve in and when I tried to start it just mad a pound clunking/clacking noise. The repair shop put a starter in it because it had stopped engaging and was going to ruin the fly wheel. I looked at it and it was eaten up pretty bad from trying to get the engine to turn over. So now all it will do is a single clunk and will not turn over. He says it could be a bad injector that flooded a cylinder or blown up in the bottom end. He did take serpentine off and still no go.
Ford 6.0L Power Stroke Diesel :: 2004 F250 Losing Power Then Stalled Out And Wouldn't Start
this morning I started my 2004 f250 drove a mile and filled up my truck. Then drove another mile and my truck acted like it was running out of fuel. It was loosing power then stalled out and wouldn't start. About five hours later I tried to start it again and nothing. about five hours after that I tried it again and it started up and drove fine.
My thought was fuel filter or the water trap. I haven't had a chance to open the filters up and check them yet. Today while I was at work I got on here to see if I could figure out what was wrong with it. all I could think of was maybe the HPOP went out or the ICP sensor. Could one of these be the problem or was I right with my original thinking and it's just a fuel filter? First thing in the morning I'm going to pull the filters and replace them.
Could there be something else wrong with my truck that I don't know about? Like I said I filled up the fuel tank then it lost power within a mile and stalled out and wouldn't start back up. Then about 10 hours later it fires up and acts like nothing happened.
Ford 6.0L Power Stroke Diesel :: 2004 F450 Won't Start / Losing Power Like Starving For Fuel
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.

I have a 2006 f250 6.0. the truck has 101k miles and to this point I have had zero issues. I am having trouble loosing power after running at highway speeds. Once I stop and begin to accelerate the truck looses power for a few seconds ,Belches smoke and begins to operate normally. I had an egr code, so I replaced egr and the problem persist. It is intermittent and does not happen if I stay under 50 mph.
View 12 RepliesFord 6.7L Power Stroke Diesel :: 2011 F350 - Losing Power - Rough Noise - Vibrating?
2011 F350 diesel with 10,000 miles. I have been experiencing problems with the truck loosing power, making rough running noise (pinging like an older diesel), and vibrating. As though the motor is bogging down. It usually occurs on small inclines or hills with the truck in higher gears and low rpms. It will also occur running on flat ground 65-70 mph. Had it occur once while turning the truck around in 1st gear and low rpms. Depressing the accelerator will bring the truck out of it.
This problem occurs randomly sometimes a couple of times a week to not at all. Took to dealer and they found no codes and of couse it didn't do it on the hour long test drive I took the mechanic on. However they did say they had two other owners come in with the same complaints, but could not get trucks to repeat the issue. Problem usually occurs in the hotter part of the day, maybe just coincidence. I had seen similar posts with this problem but no conclusions.
Ford 6.7L Power Stroke Diesel :: Truck Will Rev High In 3rd Gear Then Fall Into 4th / Losing Power For A Split Second
2011 6.7 with 3.55 gearing. Just got the truck. And it seems when its cold the truck will rev high in 3rd gear and then sort of fall into 4th gear sort of losing power for a split second. If I gas it hard, its not as bad. Usually only happens like I said when its cold. Check the trans fluid its full and looks clean. My guess is some sort of sensor or the computer???
View 7 RepliesFord 6.7L Power Stroke Diesel :: 2016 F350 Started Losing Speed Down To About 58 MPH
I have a 2016 350 dually with 6.7, with 2,200 miles. I was pulling my 11,000 LB travel trailer on fairly level ground, major interstate going 65mph. Noticed I started losing speed down to about 58mph, then started decending a long 5-6% grade, at this point I was running at 3/4 throttle to maintain speed. It felt like something was binding like the rear or engine was seizing up. No codes, all temps were fine. Transmission stayed in 6th gear, even at 3/4 throttle.
Checked trailer brakes, didn't seem to be dragging. Engine sounded like it was really laboring like it was tightening up. This lasted about 10 minutes, very slowly power seemed to return to normal but it was not noticeably changing. Fuel was 3/4, DEF was filled about 300 miles earlier. This truck since new feels like it has 150HP less than my 2011 F250 with the 6.7 I traded it on. Not sure what to do, if I take it back, if they find nothing then I'll get a diagnostic charge.
Ford 6.7L Power Stroke Diesel :: 2012 - DEF System Fault - Reductant System Performance
Sunday I received the dreaded DEF system fault message on my 2012 CC SRW SB FX4 with 7800 miles on it. Warned me that speed will be reduced to 50 MPH in 50 miles. I have a CTS Insight, so I checked for DTC's. First one was P2200 - NOx sensor circuit (Bank 1, Sensor 1), the second one was P204F - Reductant system performance (Bank 1).
After 50 miles it warned me that speed would be reduced to 50 MPH on next restart. Sure enough, Monday morning speed was limited to 50. I took it to the dealer, but I should have left it running. When the service guy started it, the fault had cleared and it no longer showed the P2200 NOx sensor code, although the P204f code was still there.
My question is, why in the world would Ford make it so that the code is cleared if the fault goes away, especially after putting you through the 50 MPH limit scenario?
Dealer did a reflash and said its OK now, but I'm not so sure. My trucks build date is 10/6/11. I read TSB 11-11-13 which states the NOx sensor module should be replaced for P2200 on trucks built before 10/11/11. Is that only for a persistent P2200?
Ford 6.0L Power Stroke Diesel :: Long Crank When Cold / HPOP Is Losing Prime
6.0 has had dummy plugs and stand pipes replaced and still has a long crank when cold. The kicker is that it doesn't happen when the truck is parked nose up in the driveway. It only happens if the truck is level or back into the driveway. I suspect it's that the HPOP is losing prime from somewhere.
View 6 RepliesFord 6.0L Power Stroke Diesel :: White Smoke / Steam Blowing And Losing Coolant
My 2006 6.0 is blowing white smoke/steam and Im losing coolant (not out the top). Pulled the EGR valve and its wet down there. All signs lead to EGR cooler? I've been reading a lot on this forum and Ill do the oil cooler at the same time. I seems VERY important to flush the coolant system before I tear into this. I am afraid of hydro locking the motor or ruining the head gasket or stretching the head studs if I run the truck. How can I do this without further damaging the engine? I am doing this myself. I'll have 3 solid days to finish this job because I have to tow my trailer in 5 days.
View 5 RepliesFord 6.0L Power Stroke Diesel :: Losing Coolant / Radiator Making A Sloshing / Gurgling Noise
I have a 2003 6.0l... When I first bought truck, seemed to run fine. Since then truck has broke down on me once. I took it on a six hour drive, and couldn't turn vehicle off, because if so, truck wouldn't start back up until cool. After getting to my destination, fans seemed very loud every time I pressed pedal, and seemed very sluggish. Drove it a couple days and boost was low and fans continued to sound like they werre engaging even when I first started truck for the day. Had truck towed to shop, because it cut off on me when driving.
At shop : Truck had air filter, water in fuel sensor, o-ring for draining plug, new ICP sensor and harness, and HFCM cleaned up as it was filled with gunk.
After shop : Fans quit being so loud, but have not had near the boost I had before issues started. Truck struggles to go from stop, and around 15 psi boost gauge starts shaking erratically. Also, I have been losing coolant in a short period of time, and can't see any leak coming from anywhere, and also my radiator has been making a sloshing/gurgling noise and it will stop, then come back all within bout ten seconds. And I guess while I'm writing, I should mention the bucking after it downshifts in about third or fourth gear giving it gas makes the truck buck until the RPMs are above 2000 or it upshifts or downshifts, and at an idle seems to miss until warm.
Ford 6.0L Power Stroke Diesel :: Losing Coolant Pressure - Pin Hole Leak Somewhere Once Shut The Truck Off
I noticed when I shut off the truck about 30-40 minutes later I'll open the degas bottle cap and notice there is no pressure.
I used a coolant pressure tester kit and pumped in 16PSI but couldn't hear or find the leak.
I'm going to buy a smoke machine in a month or two but until then, can I still drive the truck ?
I'm guessing it is a pin hole leak somewhere as once I shut the truck off... there is a lot of coolant pressure.
Ford 7.3L Power Stroke (1999-2003) :: After Wiper Motor Replacement Some Electrical System Won't Work?
I just replaced my Wiper motor last week and noticed something strange. For the last year or so when I turn on the key to start the truck, once in a while my radio, gauges, and other electricals such as windows wouldn't work for a bit, anywhere from a couple seconds to maybe as much as a couple minutes. Since my wiper motor was on the fritz, I pulled the fuse and the radio,gauges,ect. wouldn't work until the WTS light went out, then everything worked just fine, even after I started the truck and the glow plugs come back on.Since I replaced the motor everything works as soon as i turn the key. Coincidence? Or could one of the internal relays on the motor being stuck cause that?

So the 04 is rolling down the road when the cluster gauges ping, the truck loses power/acceleration but the radio never goes out. Have a new alternator and batteries passed a check. It has done it three times. We are 1100 miles from home. OBD and cigarette lighter fuse was blown as well.
