Ford 6.7L Power Stroke Diesel :: No Crank / Lost Communication To PCM
Sep 12, 2016
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...
transmission:
u0294 lost communication with pcm
Body control module:
u0100-87 lost communication with pcm
B10f1-14 key in switch short to ground or open

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.

I own a 2011 f350 diesel. So 2 weekends ago when it iced over in DFW I ended up doing a bunch of driving in 4wd. I pulled out a couple people, even pull out a semi.
After this the truck went on the fritz and gave me a CEL regarding the tcm losing communication with the rest of the electrical system. The truck was stuck in 6th gear and all things related to the tcm gear indicator didn't work. (remote start, backup camera, traction control, stability control and trans temp gauge). I did have drivability issues with the trans when it would sometimes bang gears when i would get on it suddenly and it could get generally confused at times, so generally I drove it pretty gently. The truck had to be towed to the dealer because after a while it would only get neutral of 1st gear and obviously it shouldnt be driven like that. They replaced the tcm under warranty.
The kicker is that all of that trans bs is now gone, there's no more confusion and gear banging.. drivability improved 10 fold. Obviously they updated the software but i was wondering if that was all that was needed to get this trans in gear? (pun intended) maybe they did something else?

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.

My 2004 6.0 has lost some power and the head gasket is leaking into the coolant. How long can i continue to drive the truck before too much damage is done to the engine?

I added LED lights to illuminate the running boards on my Lariat. Did this about 15 months ago and all was fine until this week and I noticed they weren't coming on any longer. Both sides are out of commission. The running board lights on each side are wired to the respective plug for the running board lights on each side. The interior lights that are on the same circuit work fine (fuse #12 in the passenger side fuse box).
So I'm scratching my head trying to figure out why both sides have gone out at the same time but the fuse is ok. It's winter here and my truck doesn't completely in the garage so I'm hoping to limit my time lying under the truck out in the cold, on a wet floor! I thought there might be another fuse in the engine compartment fuse box but there isn't, at least according to the manual.

Currently truck is in the shop after having multiple episodes where it lost power. It has 47,000 miles on it. When pushing down gas pedal, just does not want to go. Very slow to shift through the gears and get to highway speed. Turbo was not there, and there was also a hard shift/jerking from 2nd - 3rd. Did notice the traction control sensor kick on a couple of times....which was just replaced since a hole rubbed through the wiring. (took it to Ford twice before they found the problem)
They told me today that the code generator said to look at wiring but they did not find anything (heard that before) and that the fuel is possibly contaminated with DEF. If that is the case, someone is messing with my truck! What I don't understand that if the DEF does turn out to be in the fuel tank, wouldn't we have the problem continuously and not intermittently over a month after driving thousands of miles and going through numerous tanks of fuel? We drive and average of 60 miles per day just for work, half interstate/city.

This is a new truck to me 03 Excursion, the owner has done a lot, gave me receipts for a lot of work and cosmetically it just seems taken care of. About a year ago hpop, ficm, oem egr and 3 injectors. He wasn't happy with that mechanic and still having problems so went to a different (supposedly better) shop. This time turbo cleaned, all 8 injectors and passenger head was redone and put back on with oem bolts. Apparently it was found that a nut was dropped down valve cover by the first shop! Somewhere along the way the ICP and GP module has been replaced.
I've only driven it a couple times and seems great until last night. It was loosing power and in about 10 seconds died and wouldn't start back up. Pops but doesn't stay running. WIF dash light on and no CEL codes. Not sure where to start/what to do. I've paid for most of it and was planning to pay the rest and transfer title but I'm not comfortable doing that till I'm confident it's good to go.
I drained the separator and seemed to gush out like it should and don't think I saw water. I'm planning to take the sensor off the filter there, inspect and clean it but I don't imagine that's the problem. I do see oil coming on the back of the engine and front of tranny on the drivers side... maybe ICP is all oily and failed? I don't know much about these, just been trying to read. What should I do as some first steps? Do I need some sort of scanner? It seems like it's starving for fuel. It was about 1/4 of fuel when I bought it and filled it up the night I took it home and have put about 80 miles on it since. Is it possible it's got bad fuel or water?

I have a 2005 6.0. I just got done doing the HPOP seals, injector o-rings, stand pipes and dummy plugs. I have drove the truck 600 miles since the work with no problems other than a wiring issue I got fixed...
I was driving at highway speeds, and all of a sudden I lost power and got a shake when trying to accelerate. I pulled over and turned it off, and when I went to restart it I got nothing at first, then it went to what seemed like a partial crank followed by a thud. So I'm thinking I just hydro locked it. I waited a few mins and tried again, and it started but had a few knocks for 15 seconds or so, then it ran rough with smoke pouring out of the exhaust (grey then turned kinda white).
I the only codes I have are for the egr which I've had unplugged for a long time, and a glow plug code, but when I started it back up, I had no codes. I'm baffled. I did notice I have oil on my oil filter housing at the cap, a little oil had slung on to my wire harness and my intake. I don't even know where to begin!

I drive an 06 f350 with a 6.0 diesel. My truck has quit on me twice in two months. It lost power then stalled and would not restart. I had just changed fuel filters but checked them anyway to see if they were plugged. They looked clean so i put them back in and the truck fired up. It ran good then two months later it did the same thing.
I noticed I could not hear the fuel pump so i pulled the cap off if the top fuel filter to see if there was fuel in it, and heard air being sucked in (or pushed out?) as i loosened the cap. I put the cap back on then turned the key and i could hear the fuel pump working. I waited for glow plugs and it fired up. Is my engine getting vapor locked, or sucking air? If so then why would it only happen every now and then instead of continuously?

My uncle bought an '05 that stopped running one day. He was driving down the road and engine lost power. He was able to coast into his driveway. Unfortunately, it's been 10 years since I've work on a 6.0 and no longer have any of my computers.
He did state there is no check engine light. He's going to change the filters today / tomorrow. I'm hoping to make it down there this weekend to look at it, but what to look for. Even more unfortunately, we really don't have any specialty tools or gauges.

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.

Ok yesterday while driving my truck the glow plug light came on couple times and lost power but the light would turn off and power came back. It has done this before and it was the injector harness grounding out on the engine. I replaced that last time. I checked over the knew one and did not see any chaffing on the harness.
Now this morning I go outside to start it and I can hear my fuel pump and vacuum pump but injectors wouldn't cycle. It has also done this before but I could never figure out why. Last time I tore into it checking through my wiring harness and couldn't find anything. When I put it back together it started fine.

So I was driving down highway when I lost power. Engine was still running just had no power and would blow black smoke when I got on the accelerator. I pulled the EGR valve and noticed it had rocks stuck keeping the valve open. Cleaned it all up and put it back in. Went for test drive and seemed good again until few miles in same problem. Took it apart again and same thing.. rocks. I did this 3 times with same results...rocks getting stuck in my valve.

It's a 2004 6.0 excursion with about 190,000 miles. At 185,000 I pulled the motor and did new oem head gaskets, Arp head studs, bulletproof egr cooler and oil cooler system, bulletproof 48v ficm, strictly diesel regulated return, and I've been running gear heads srl tune before and after the truck was rebuilt.
Recently the truck has been acting up at random times. While running the gear head srl tune, the truck will lose power, the boost gauge on my edge insight will get stuck along with Icp psi, the water in fuel light and glow plug light will come on, and then after a few seconds it will clear itself and run fine. Last night I was on a two lane road and putting my foot into it and the truck did the same thing where it loses power, but this time the truck actually died on me while I was cruising at 60.
Same lights were on but this time the cruise control light fluttered while the truck was in the midst of dying. I tried restarting it and it took two sets of cranking before it fired and stayed running. On the way home I babied it and the truck lost power and the Rpms dropped and only the glow plug light came on. Got home and ran codes and I got camshaft and crankshaft position sensor codes and I tuned it back to stock, drove it around, and the truck ran fine, but while on a stock tune I am getting a egr valve code.

So today on my way home from work. I got off at my exit and when I went to step on the gas I lost power and the truck wouldn't exceed 15 mph. It would just rev up and down. It was pouring white smoke from the tailpipe. At one point it went back to normal and started running fine for about 10 seconds. Then it went back to doing the same thing losing power and spitting smoke. I limped the truck into a parking lot and called a ride. I'm having a tow truck pick it up on Monday and take it to the dealership. Is this a head gasket issue? And I feel like it's going to be expensive. 2006 F250 6.0L .....

We got "bad" gas in Feb, 2016, had to replace entire fuel system. Haven't driven the truck but 4000 miles. Last week, she started spitting and sputtering and lost power. We could see fuel pouring out. NO CEL. Towed (AAA has paid for itself several times over with this truck) to dealer that replaced the fuel system, still waiting to hear from them. Does this sound like it should be under the warranty for the work they did? We have averaged a huge repair bill about every 3-4 months on this truck, 2011 F250 Lariat, 8cyl, 6.7L, since we bought it 2 years ago.
