Lately it seems that my 6.0 cranks over longer before it starts. it used to turn over quick and start not it turns over at least 5-8 seconds maybe more. .
View 7 RepliesWhere to monitor or what to check. The past few weeks this truck all the sudden went from a quick starter(barely hit the key and it would pop off) cold and hot to one that consistently cranks for around 5 seconds before it starts. Doesn't matter if I wait for the glow plug dash light to go out when it's sat for two days or if the engine has a ECT of 198 F and was just running 5 minutes prior...it still cranks over for 5 seconds before starting. Seems like it's an electronic issue vs mechanical, but that's just a guess.
The truck runs, drives and tows excellent outside of this starting quirk...so I know I shouldn't complain but this isn't right from what it used to start like and seems like it's a warning that something is likely to fail down the road. I'd Rather find it now than when 100's of miles from home if possible.
I updated it with better dummy plugs, standpipes, STC fitting, rebuilt FICM, 2 fresh batteries, new fuel pump, ICP sensor all within the last 10K miles. I scanned it with a code reader and found no codes in the history and the check engine light is not on.
Monitoring with a Scan Gauge all inputs seem normal for what I've read on this website with the exception of SYC it says 0? Which should mean it would never start I think but yet it does? I checked my code numbers from the list and I had it entered correct. Is this my issue a bad crank or cam position sensor?
I have a late model 2004 F-350 6.0 powerstroke. 182K miles. Auto Transmission
What happened. Condensed version
Left house, drove out to highway, got on highway. Everything feels normal.
About 1 mile of going 70mph, I notice I can no longer accelerate. after 1/2 mile, I begin loosing speed, and engine will not rev past 1000 rpm. I eventually pull over (another mile), put in neutral and will not rev past 1000. put in drive and start to idle to highway exit. it gets about another .5 mile and begin going up a hill when it completely dies. Will not restart.
No prior issues with the truck. Full tank of fuel.
What I have tested so far. Ficm 48.5 volts cranking. Icp .225V KOEO, .875V Cranking. LPOP is registering pressure on the dash. No Fault codes.
I have gotten it to start twice now, one time it allowed me to rev to 750 rpm, where i used 4 low to make it onto a trailer. second time would not rev at all. idling at 250-300 rpm.
That same night as it died, I drained the transmission pan/ TP filter and filled with 8.5 Quarts of Mercon LV. This is the first time I have done this since purchasing @ 161K miles. Everything seemed normal, no leaks present.
Also my buddy showed me how to enter the dash test mode and we cycled through these. Not sure if this is relevant.
So, What do I test next? I don't think its HPOP issue since the ICP is reading .875 volts at crank. I did unplug the ICP and it still would not start. I don't think its the injector side of the ficm because they buzz as normal with koeo, but this is a possibility as I don't have equipment to test. Egr valve is clean for age of truck.
Would it be possible that the Mercon LV knocked crud loose in the transmission causing it to fail/seize? would siezed tranny cause the engine to behave in this manner?
Fuel bowl on top of the engine was full of fuel. I have not pressure tested it yet as I can hear the pump running during key on.
could i have a bad crank or cam sensor?
Multi-injector failure?
Bad Icp with HPO failure?
My truck ran great when I got to my house that I turned it off and tried turning it on again it wouldn't turn on I check the fuel pump it works I checked the injector if it was getting fuel it was .I'm a stand still, where else to check? What to do?
View 14 RepliesI just bought an 05 F350 and it starts fine when cold but after I drive it a while will not start even after sitting for up to an hour (overnight cold start fires right up). I replaced 1 battery and alternator and it started up right after install but after driving for a while still have the problem - cranks fine but will not start.
Buddy of mine has the same truck (just a 250) and had this same problem recently and had to replace the High Pressure Oil Pump, which was super expensive! This is my first diesel truck and it runs like a champ (once it starts!)
2007 6.0 my dash lights will flicker when the key is turned on and the truck wil crank but won't start, but when the lights stop flickering truck starts .. How to fix the flickering dash light?
View 2 RepliesI 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.
View 10 RepliesA 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.
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?
2007 6.0l cranks but no start. Read all the forums and I think I performed all the checks. Getting a ficm/ cam sensor/crank sensor no sync. I'm also getting 84.70% at the ipr while cranking. Do I have multiple problems? Watched videos on either the ficm or ipr percentage but not one that had both problems. Getting injector clatter and fuel pump runs. Didn't see anything obvious with the harness.
View 14 RepliesWent out to start my truck this morning and it wouldn't start. Cranks fine and almost started once but died. Checked all fuses all my voltages are good. Oil and coolant are good. When I turn the key on I can hear the fuel pump and sounds like it's priming correctly. Might be an issue with a clogged fuel filter? Maybe? Haven't had any problems or issues otherwise.
View 6 RepliesI have a 2007 F350 6.0 Diesel. Truck starts and runs great for about 10 miles and then loses power and slows down til it dies, it does this without any kind of warning and does not rattle or anything. If i let it sit for about 15 min it will start right up and drive fine for another 10 miles or so and do the same thing.
It did the same thing in December but would not restart at all and the ficm was the cause at that time so i went ahead and replaced the ficm just to eliminate it. I also replaced the fuel pump and the ipr and icp valves are good. The only engine code has to do with the fuel level sensor and that has been on for a year. The egr was recently replaced, the hpop is putting out the psi that it is supposed to and there are not any internal air leaks.
My 2007 F350 CC DRW KR has developed a serious oil leak recently. The oil runs down both sides of the bell housing but seems to be worse on the passengers side. It only leaks after five or so minutes of running and not while off. I have searched literally hundreds of threads and found only one that seemed similar and the resolution was never posted.
The truck is stock with only a turbo back 4" exhaust. I initially thought of the STC fitting failing and cracking the rear engine cover, but I still have very good ICP (650 almost immediately when cranking and at idle, 3000+ when on the throttle).
I plan to pull the turbo next weekend to check the drain tube and HPOP cover as well as checking/replacing the STC fitting (since I'm in there).
I just bought a 2007 F350 CCSB 6.0 auto 4x4 with 113k miles on it, it does have the 5th wheel goose neck trailer hitch in the bed...anyway of course when I looked at the rig everything checked out and now I am getting a U1900 for ABS CAN communication...I should add that the ABS Light itself is not on, just the CEL...I have a feeling it has something to do with the wiring that the PO maybe had done to wire for his 5th wheel hitch?...I checked all the ABS related fuses in both fuse boxes and they're all fine...
While reading another post on the possibility of the brake pedal position switch up on the pedal itself being bad, someone mentioned that the wiring may be jacked up due someone adding wiring in for the 5th wheel hitch...I also checked the brake pressure switch on the nose of the master cylinder and that looked clean although I didn't test it...should I just replace these since they're pretty cheap or is there something I should look for in the wiring underneath the dash? Oh and of course my cruise control isn't working either...likely because of this ABS wiring issue..
Truck is an '07 F350 Supercrew, 8ft bed, SRW, 2wd. I bought the truck last month and noticed a low frequency driveline vibration starting at about 45 mph and is noticeable to about 65 mph. Feels like a bad u-joint. So I pulled the drive shaft (two piece) and checked the joints. They seemed find so I sent it to a commercial truck shop that does driveshaft work. Had the joints replaced and the shaft rebalanced.
Re-installed drive shaft and went for a test drive. No real change in the vibration. The hangar bearing seemed fine so it wasn't changed. Doesn't feel like a wheel out of balance. My experience tells me its a drive shaft.
i have a 2007 f350 6.0 and it was running fine. I parked it in my driveway for a couple of months and then went down one day to start it. The first day it started but the second day i went down it wouldn't start. it would crank but wouldn't fire up. I changed the oil, repaired the FICM and still got nothing. Then i took a generic scanner and got the code p2285. I replace the ICP but still no start. I have also changed both batteries. I'm not getting any codes right now either. What is going on?It has around 229,000 miles

View 7 RepliesMy 2007 F350 6.0l DRW LARIAT battery voltage was too low to restart her while out and about today. I did notice that she seemed kind of when I started her up leaving my town to got over two towns away. So i set my Scan Gauge to check voltage and it was low considering she was running, in the low 12V range with radio and a/c running. So I figured the regulator is on it's way out but I this be able to restart her up. Anyway after a jump she started right up and I was able to get home no issues. After I jump started her the check engine icon was illuminated with DTC P0606. I'm not 100% on why this trouble code was recorded other than the fact that I tried to start her up which caused battery to fall below the 9.6V threshold to power the PCM. The voltage was still low after jumping her, so I figured i better swap in a new alternator but what kind. I hear that the alternator is an issue with this truck, so what should I get?? What alternator is proven to last on these trucks?
View 14 RepliesRecently 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.
View 3 RepliesI just bought a 2007 F350 6.0 two days ago, so I was giving the truck a good wash today using a electric pressure washer. The engine bay was pretty dirty so I decided to take some soap and a brush to it. After cleaning it I let it sit for a while in the sun to dry. (engine was stone cold). After it had completely dried out I go in and it cranked right up. I let it idle for a good minute-minute and a half put it in drive and pulled away slowly, right when I touched the accelerator it started running rough, so I popped it into neutral and let it idle for a sec but it was still running really rough so I cut it off not wanting to damage anything worse.
I let it sit and tried to start it again, it just turned over and over. I checked the oil level it was good. So I pushed it back into my driveway to figure it out. I took ICP connector out and tried to start it, just turned over and over. took fuel filter out it was just replaced 2K miles ago it looked a little dirty but not super bad. I put that back in. took icp out again and tried to start it and it started but ran super rough and was dumping black smoke out.
I checked back all ficm connectors and they were all connected. I haven't checked the voltage on that yet, but plan to do that tomorrow. the previous owner had the ficm go bag about a year ago and he sent it off to ficmrepair.com and they fixed it for him. also he had the stand pipes and dumby plugs done as well as the stc on hpop. im kinda at a loss on where to go now other than to check voltage on ficm.

Yesterday, while driving home from a weekend out of town trip, all of sudden lost throttle control. Just went to idle while at cruise speeds, could pump pedal and no response. Then got pedal control back and seemed to run normally.
This happened several times. Hubby suggested moving the adjustable pedal which I did slightly. Although I was not using the cruise control, we had a sense that maybe it was engaging??? So I hit the off button a couple of times. After these two interventions, drove the last 80 miles home with no further incidents.
Today, we checked codes and had a PO231, Fuel Pump Secondary Circuit Low. I don't think that is our problem with above based on research, but we will look into fixing that too. We are thinking TPS or a position sensor on the accelerator pedal. We could replace those easily ourselves.
