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.
View 6 RepliesI know this is an old subject that comes up from time to time. Most will notice it after an oil change or the first oil change anyway. Yet, some will never notice or experience the sound.
It is when you first start the engine, it has been described as a can of marbles being shaken or popping noise, maybe a metallic knock.
I have 17K on the truck now and this seems to be getting louder and more annoying. Sometimes it is louder than other times, and sometimes I don't hear it at all. I have always changed my oil right at 5,000 mile intervals. Fuel Filter at 13,500.
My new to me (2K miles now) 2013 F350 with 52k miles just developed a knock. Oil changed 600 miles ago, Oil level good. No codes or CELs ...
YouTube...
Today I noticed this burning smell under my hood and a bit of a engine knock on idle... It doesn't knock all the time tho ??
View 7 RepliesI have a 2016 f350 super duty with 6.7L engine, at random times engine sounds like it has a rod knock, give more fuel, it goes away, driving at 40 to 55 mph the whole vehicle shakes all at different times and different days vehicle has under 6500 miles want to now anything before going back to dealer..
View 6 RepliesI noticed a rough idle after driving an hour with a 6000 lb trailer and stopped at an offramp. Had no performance issues to that point in an hour drive. Then I noticed a good amount of white smoke coming out of the exhaust. The idle felt just like when I had a contribution/balance code on #5 a year ago, and a new injector fixed that. Before long (10-20 minutes later) the idle got real loud, like a big knock/loud tick every revolution.
I had a bunch of stored codes, so I reset them and later found a P0281 - Cylinder 7 contribution/Balance and P0404 - EGR control circuit range/performance were the 2 that came back. I drove it 2 more hours to get home. It ran well under load, but coasting or stopped gave the loud knock, and stopped and idling was a rough, inconsistent idle. It even stalled on me 3 times when braking for a red light (auto trans). There was a lot of white smoke all the time, plus a little dark smoke on acceleration.
What would you recommend for troubleshooting steps? I could put a new injector in #7 and clean the EGR valve, but want to have a good idea that will fix it first. Is there a good chance I have a messed up piston in #7 now?
Codes I cleared:
P0148 Fuel delivery error
P0234 turbo overboost (i know i need to pull and clean the turbo anyway, unrelated to today's issue)
P0281 Cylinder 7 contribution/Balance
P0404 EGR control circuit range/performance
P0670 Glow plug (I had the module unplugged a while ago)
P0683 Glow plug (I had the module unplugged a while ago)
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
View 9 RepliesWe 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.
View 14 RepliesI have a 2011 F250 4X4 Supercab 6.7L that has a highly annoying knock/rattle (you can't hear it) under the front passenger side floor. It feels like someone is tapping on the floor beneath your feet any time you hit a bump or when on a rough road.
Its been in at least 5 times in 2 yrs with cab mount adjustments/shims, cab mount replacements and realignment of the exhaust and brackets. The knock has been there since about day one (I assume anyway, I'm rarely on that side of the cab) and have burned up my 36k warranty, although I'm told i'm good because it is pre-existing.
I keep insisting its in the suspension and keep being told they can't find anything. The mechanic indicated that this is a known problem, but Ford has not put out any service bulletins other than to do the cab mounts and suspension. Has anyone had this problem and found the solution?
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 Repliesthis 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.
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 6 RepliesI have a 2004 6liter. I parked one day two weeks ago and a went out last week to move it and I will only crank over. No fire No start!!!! Have new batteries. New fuel filter and have fuel coming in to the fuel bowl. I have gone over the harness, checked my fuses. I do not have a reader or scanner. Any recommendations. I want more than just a code scanner.
View 14 RepliesFirst of all, I have 2004 f-350 92K miles with a stock 6.0 - EGR deletes and new oil cooler is the only updates.
Two weeks ago I had an issue pop up. When I tried to start from a dead stop there was no acceleration, it would idle ok but when i pressed on the peddle NOTHING! I called the local diesel guru, he recommended I change the fuel filters. After I did this there was a tremendous improvement in performance.
After a few days of normal driving, I noticed a subtle reduction in throttle response. Today I noticed a slight lag when accelerating which lasted about 3 miles until there is once again no acceleration. It will start normally and idle is a little rough, but will not accelerate even in park the engine is extremely slow to accelerate.
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?
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
IPC 3 KOEO, 1100 crank
IPR 14.1 KOEO, 46 crank
IPC volt .23 KOEO, 1.23 crank
Passed bubble test
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?
View 9 RepliesI 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.
View 13 Replies04 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.
My husband and I purchased a 2004 f250 king ranch 6.0L... We love the truck, despite the headaches. We took it to a dealership and spent just under $5k in parts, drove it for a month (everything going great) until we shut it off to bs w a friend and it won't turn back on. It's been sitting for 4 days and nothing. Cranks and cranks, but won't actually start. We are pretty handy with gas trucks, but this diesel is out of our element- we are getting better though haha!
We looked on here and saw that the no start could be bc of the FICM - swapped it out- not the issue.
Now the codes being thrown are P2291 & P2285 (or so my husband says)
We are thinking if we replace the ICP and that fixes it, we won't need to do the HPOP. Or do we need to do it as well? Are we on the right track?
When we shut it off, it didn't have any lights on, no gauge fluctuations, or any "red flags". This is why we are stumped!!
(Ford dealership fixes: 2 batteries, new starter, new tank cap, new oil cooler, maybe a few others- receipts not infront of me).
Like I mentioned, we've already dropped more money than we have into this truck and now it's taking more- we love the truck and once it's fixed we will "have a new truck" it just sucks bc my husband works afternoons and I'm a stay at home mom with a 14mo and this is our only vehicle.
I have a 2004 late model 6.0. My son was driving it and parked it in the road told him move it and it wouldn't start. I got it to start and it ran for about 10 seconds. I pushed it in the drive way and left it over night. In the morning there was oil on the driveway. I found that there was the wrong oil filter put in and there is no oil pressure at start up and no oil entering the filter housing. Where to start would be great. I am going to get a Scangauge II to get more information. Could be the ICP?
