Ford 6.0L Power Stroke Diesel :: Extreme Lag In Acceleration / Occasionally Doesn't Want To Start
I am noticing a extreme lag in acceleration. When taking off from a stop it lags really bad then acts like I floored it. My FMP is 48 sometimes dropping to 47.5. FLP is 13 sometimes dropping to 11.5 during starting. Occasionally it doesn't want to start, like its not getting fuel. New batteries 3 months ago. Also has blue spring. Its a 2005 thats never had anything done to the FICM, so its kind of old to begin with. I read in another thread that the FICM relay should be replaced occasionally, so may that could be contributing to some of my probs.

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.

I have a 2007 6.0 crew cab that I'm having some recent issues with. When starting cold in the A.M. the truck will crank, start for a half second then shut down, after about 3 times it will finally catch and keep running. I'll let it warm a bit, then for the first few minutes of driving it will have a pretty noticeable surge on acceleration only, not at idle.
The surge goes away mostly after warm however you can still feel it happening between 22-2700 rpm and can just see the rpm moving back and forth a little. Lastly the fuel mileage has dropped a good amount. If I baby it around town I'll get 10.5 and can see 9ish occasionally.
Truck has brand new ford fuel filters, ford blue spring, fresh oil change, FICM has 3k miles on it, new batteries in last 6 months. Turbo egr oil cooler done in last 20k. Currently has 120k on it.
Ford 6.0L Power Stroke Diesel :: 2004 F350 - Severe Shudder While Under Acceleration
I bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.

I have a 2004 f350 6.0 it has 73000 miles on it. I've had the truck for about a month and its developed a slight stumble, hesitation. It does it during idle and acceleration, if I give it more throttle it smooths out. The cel is not on and there are no stored codes.It did this a few days after i bought it,i noticed the map sensor was broke in half so i replaced that and it smoothed out.But it came back. Exhaust is clean no white or black smoke at all.

Pulled the trigger today and bought a 2004 F350 DRW King Ranch with 200000 miles. Using Forscan Lite on my iPhone, KOEO FICM voltage was right at 48. During start it went up a bit. While out for my highway road test for EOT/ECT differential (never went above 10 degrees).
I noticed that the FICM voltage would drop to the bottom of the Forscan scale (40 volts) when I was accelerating and then go back to 47.5 when I reached my cruising speed. Is this normal?
Batteries are brand new from Ford. I didn't notice the battery voltage. Truck seems to run great to me, but this is my first 6.0. I also got DTC's for all 8 injectors saying Injector Circuit Low.
Ford 6.0L Power Stroke Diesel :: 2004 F350 - Poor Acceleration When Engine Is At Operating Temp
I have a 04 f350 6.0 with about 195xxx miles on it. The other day my truck started acting up. It starts and idles without a problem and drives fine till the engine gets to operating temp once there I cannot accelerate quickly like getting onto the highway to get up to speed it just the motor just goes quiet and won't accelerate. It usually does this a little after 2000 rpm. I can let off the throttle and slowly get to speed as long as I don't go past 2000 rpm. No check engine light was not on scanned it and got p0611 for the ficm. I tested the ficm and it read 48v with key on. While truck was running I got 46.xx v then Started to climb to almost 48v. The truck was warm but not at operating temp where the problems starts(didn't have time to let it warm up all the way) could these symptoms be the ficm still? What else should I test?
View 5 RepliesFord 6.0L Power Stroke Diesel :: 2004 - After Start Up Rough Idle And Power Lag?
Have a 2004 f250 that is having issues. Once the truck is started the idle goes from normal to loud almost sounds like its going to stall. A few weeks back the same happened when i was on a red light. It choked almost to where it was going to die. I accelerated when light turned green and would not move at all. I had to literally use full throttle to get out the road at about 5 mph. I pulled in to a gas station and fueled up as i had a quarter of diesel left and it stopped the rough idle and power starvation once i started the truck up again. It sees like this time its getting more persistent... FML AND THESE 6.0 problems

We have a 2004 6.0 that would not, start when hot. Now has been sitting awhile and still won't start. Have about 400 psi icp. Also this is a new motor that only has about 10,000 miles if that much. I would not, think the o-rings in the hpop system would have already failed, and being a new motor they should have the update with backup washers right? Unplugged the icp sensor and will not start. I have cup and CMC sync as well as ficm sync.

I have a 2004 f350 with a 03 bullet proofed motor. The truck did not have any power and the turbo wouldn't support until I put a new vgt solenoid in and it ran great for about 3 miles... Stalled doing 65 kinda lacked power while accelerating but got up to speed quick. I pulled over and no start. It is running error code kam on pcm from disconnecting batteries but could this cause the stall and no start? Or should I be looking into icp sensor?
View 2 RepliesFord 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.

View 14 RepliesFord 6.0L Power Stroke Diesel :: 2004 - Won't Start Just Turn Over?
2004 Excursion, won't start, just turns over. Pulled the cap off the fuel filter and it's filling fast so seems to be getting fuel. FICM replaced with a unit from Ed a year ago, along with a high output alternator, tests at 49 volts at key on, 48.5 cranking.
Truck started up fine last night, went for a drive with the family through Christmas lights. It has been running very rough at start and then smooths out after a few seconds. Went to start it up today and it just turns over, never fires. Unplugged the ICP on the passenger side valve cover and no improvement.
Pulled codes and had P0269, P0672, and P0676. Looks like a couple flow plug codes an injector contribution code.
What else can I check before pulling the valve covers?
Ford 6.0L Power Stroke Diesel :: 2004 - Crank But Won't Start?
ok, so after all the work done (headgaskets, head bolts, egr valve, ipr valve, egr cooler, oil cooler, blue spring kit, new ficm injector harness connectors), this is what I'm left with on start up. I am now getting no SYNC -0
I had ficm sync before i changed the connectors on the injector harness (last thing i did besides blue spring kit). Has this motor turn this way? And my glow plug light now comes on during and post crank along with a weird fuel light with 3 teardrops I've never seen before. I need to check this out.
48.0 ficm KOEO, 48.3 crank

Ford 6.0L Power Stroke Diesel :: 2004 - Oil Priming Before Start Up
Getting ready to fire this late '04 6 liter up tomorrow. Did HG and Studs,,etc.. My question is Oil Priming before start up, I saw the video on youtube about pulling a relay for the ficm, my owners manual only talks about a fuse for the ficm and its behind a panel on the dash. Did Ford wire these trucks differently?

My 2004 powerstroke recently started making a loud knock during the process of starting. Will make the sound warm or cold, however I mostly hear it when the truck is warm as it cranks a little longer and about two seconds into the crank something starts knocking. After the truck starts it runs perfectly fine.

I have an 04 6.0. My truck was running perfect, no problems. I start my truck, it started idealing rough for a couple seconds then just died. After that it just kept cranking and no start. There are no codes, tried unplugging the ICP sensor and nothing. Checked the fuel filter and its filling up with fuel before cranking. Oil is at a good level. FICM is reading 46.5-47.5 before cranking. Checked the ICP Psi I'm only building 11psi and HPOP was replaced in October.

04 Excursion with 03 motor. I had been getting a no hot restart problem. Now it won't start at all.
FICM 48
rpm around 155-175
ipr goes to 77
icp jumps to 475 and drops back to 400-425
My problem started in Virginia, so I got it started cold and drove all the way home to Indiana without shutting it off. Pretty much been parked since. I've driven it 4-5 times. Now it won't start at all.
I have some LPO problem: I posted it November 2013 [URL] ....
After that I replaced LPO regulator, front cover gasket set, LPO cover (Ford tech said my gearator was fine). I don't think this problem is fixed still
We tried to do a leak down air test. Honestly couldn't hear much of a difference with IPR on vs off. Pulled IPR, found the screen in tact but the plastic pieces that hold it on were all rotted away and broken. I replaced with a brand new IPR to be safe.
I'm not real sure what to look into next. Right now I have both valve covers off and tried to look for a HPO leak in valve covers while cranking. I don't see any oil anywhere coming into the valve train. Shouldn't there be LPO somewhere?
My oil is old now but it was T6 and brand new when this problem first occured. Motorcraft filter but the cap is river city diesel billet cap [URL] ....
Could it be as simple as the oil screen to the HPOP or the check ball in the pump? Can the LPO gauge dropping be related to the no start now? Are there any techs that live in Southern Indiana and want to make some side cash? Last thing I want to do is bring this to the local shop or even worse the dealer. Last time the dealer said they wouldn't touch it because the tuner and EGR delete and the local shop left it sitting for a month and hadn't even touched it.
