Ford 6.0L Power Stroke Diesel :: Rough Idle And No Fuel Pressure

I head out to work this morning and truck drive fine. I do not get on it. I cruised on the highway for 12 miles at 70 mph. I get to a traffic light and then it begins to idle rough and my fuel pressure gauge reads 0. I replace both filters over a month ago and did the blue spring upgrade at the same time. I've put over 2000 miles on the truck since then without issues until this morning. Also the fuel pump was replaced by the dealer a year ago in July. No check engine codes. Where do I start looking?

Ford 6.0L Power Stroke Diesel :: 2005 F350 Running Rough - No Power To Move

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didnt have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines,harness,pump,sending unit ,tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.

So I took that stuff to garage had them swap it out and now they said come get the truck they wont work on it anymore that now it needs 3 injectors and they wont touch it with aftermarket fuel system on it. So I go to drive it home and it starts but runs rough and u can hold it to the floor and it wont budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now .

Ford 6.0L Power Stroke Diesel :: 2005 - Rough Idle - No Power - Black Smoke?

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.

This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....

Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.

However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine

Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

Ford 6.0L Power Stroke Diesel :: Running Rough After Putting Fuel In Truck Now Won't Start

This has me puzzled to no end. After my son had put fuel in my truck it began to run rough, and had to be towed home, and now won't start. Now the first thing I thought was that he put regular gas in. But he was sure he had not ,and the receipt from the pump indicates diesel. It was hard starting before this happened.

1st Misfortune of having gas put in instead of diesel and did your vehicle run afterwards.
2nd Here are my readings from my scangage:

Sync Yes/1, Ficm main power 48.5 v, ICV .17 (2.01 when cranking). ICP 1572. IPR 50.7.

Checked upper fuel filter for bubbles, none.
Engine oil pressure comes up immediately on cranking.

Don't know what else to check, these readings look fine to me. Only the fuel is something I'm not 100% sure of. It does smell like diesel not gasoline.

Ford 6.0L Power Stroke Diesel :: 2007 - Real Rough And Stalled - Fuel Pump?

I have a 2007 F550 with a 6.0. Truck started running real rough and stalled. I was able to start it back up after a bit but within a few blocks it did the same thing. Was very similar to problems I had with clogged fuel fuel filters before I changed the tank to a plastic one. I pulled the filter and housing on the rail and cleaned and replaced the filter. There was no debris in there. Changed the filter on top of the engine too. Cycled the key 5-6 times. I could hear the pump running but the filter housing on top of the engine did not fill up; all I saw was a very little bubbling and gurgling sound.

I opened the drain on the rail filter housing and a little fuel came out but not as much as it should have. Cap is tight, don't see where I could be sucking air. I'm thinking the pump may be shot? Only other thought I had was maybe I switched the plugs on the housing on the rail but I really don't think I did. There are 2 plugs on the right hand side. Black plug is plugged into the lower position parallel to the ground while the gray plug is in the higher position.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Rough Idle And Low ICP Voltage

My truck is a 2005 f350 6.0, all stock except for an egr delete and 4 inch cat back exhaust. I recently did an oil cooler replacement and egr delete, resealed all 8 injectors, and fixed some wire chaffing at the FICM. it's running great with the exception of idling. It seems like it's idling low but the gauge stays at 750. If I hit the high idle switch, it does fine. Red lights are stressful because it shakes and sounds like it's going to die but never does. I'm posting screenshots of my Torque pro.

I have a SC2 as well but I honestly like Torque better so that's what I use most. I know my ICP is low, but 8 don't know why. No oil in the connector, and no change when I unplug it. The ICP sensor may be a month old with 1000 miles on it. This was taken at a hot startup, sitting in park. When i say hot, I mean I had driven about 60 miles. This is sitting still in drive. ICP voltage finally climbs over 1.0 when i get going about 15mph at around 1250 rpm. The second pic the ICPV is actually higher than normal. It usually stays at .8 until I give it gas.

Ford 6.0L Power Stroke Diesel :: 2005 - Poor Fuel Mileage?

I just bought my first diesel truck back in November. It's a 2005 F-250 with the 6.0L and the 5 spd torq-shift automatic tranny. Last weekend I drove the truck to South Carolina, about a 600 mile round trip from where I live. On the trip the truck only got 13 mpg! I wasn't towing a trailer and the truck was empty except for me and my suitcase. It's not loaded up with mods or anything, it's completely stock power wise.

I'm extremely disappointing, especially since a friend of mine has a 2006 F-250 identical to mine and he gets up to 21 mpg on his. What can be done to improve my mileage? I'm not a lead-footed driver, and the trip was done with almost all interstate and highway driving, very little driving on back roads or stop and go. If this is the best the truck will get, I'm going to sell it and buy a F-150!

Ford 6.0L Power Stroke Diesel :: Truck Starts / Running Rough Then Die - Fuel Draining Out Of Bowl

2004 F550 with a 6.0. I had to clean out my fuel tank, replace the HFCM and filter on top of the engine. When I start the truck it will run for 30 seconds or so, start running rough then die. I opened the cap on the fuel filter housing on top of the engine to make sure the fuel was getting there. I turned the key on and the fuel bowl quickly filled up.

After a short time however, the fuel drained out. To where I do not know. I don't think this is normal as every time I've changed the upper filter on a 6.0 it is always full of fuel. Why could this one be draining out and could that be the issue why the truck dies after starting and running for a short period of time. I changed the o-ring on the cap and the new HFCM was purchased from Ford.

Ford 6.0L Power Stroke Diesel :: 2005 F250 - Rough Time Starting When Cold

I have an 05 f250 6.0. We have started to reach 38 at night here in northern IL already. The trucks been having a rough time starting and it's not even that cold yet. Any recommendations on the truck that I can do to have easier starts. Sometimes cycling the glow plugs 4 5 6 7 times isn't enough to get her going. I plug it in most of the time on bitter days in the winter but sometimes I leave it parked where I cannot plug it in. The batteries seem just fine. I think one is a little weaker so I will get new batts.

Ford 6.0L Power Stroke Diesel :: 2005 Missing / Truck Started Running Rough

So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.

Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.

Ford 6.0L Power Stroke Diesel :: 2005 F350 - Rough Starts And Erratic Idle

A 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.

Ford 6.0L Power Stroke Diesel :: 2005 F250 - Fuel Gauge At E With 1/2 Tank?

2005 F250 Superduty Crewcab 4x4 6.0L diesel/auto

Wife drove the truck before me and bunched the floor mat under the pedals. I didn't notice the mat issue when I drove the truck today. I accelerated fully after doing a left turn onto a busy highway. The motor spun up hard with the accelerator floored but because of the mats, the pedal stuck all the way down. I was approaching stopped traffic while under full acceleration and I shut the engine off and pulled over to the shoulder all while braking hard ( it was a hell of a ride!). I freed the pedal and restarted the engine.

Now, despite a bit less than 1/2 tank of fuel (I have the 38 gal tank), the dash readout was showing "Low Fuel", the gas gauge was below E and the engine was running like it was running out of fuel. I turned the engine off again and left it off for 1/2 hour before restarting it but the gauge and engine still behaved the same. As I drove to the nearest diesel station, the engine was not running "right". Of course the station I pulled into had 1 diesel pump and the pump was broken.

Because I thought I might actually be out of fuel, an understanding stranger took me to the store to buy some gas cans and then to another station to get 6 gallons of fuel. I got back to the truck and added the 6 gallons of fuel. When I turned the key on, the fuel gauge immediately came up to 1/2 tank. I then drove to that other station and added another 15 gallons of fuel to fill it. This confirmed that I had about 18 gallons of fuel in truck when the "Low fuel" warning occurred.

So, what the heck was going on with the fuel gauge? I am sure the "Low Fuel" warning is tied directly to the gauge but why was the gauge reading low? Is it possible that the "Key-off" while under full acceleration followed by hard braking had confused the ECU? I am just trying to figure out if I have a fuel sender problem or a confused computer that corrected itself. Until this incident, the fuel gauge has never been a problem but the wife messing up the mats has been an issue!

Ford 6.0L Power Stroke Diesel :: 2005 / E350 Van - Rough Idle Stalls / Hard To Start

Rough idle I have had for little bit.Would stall out at idle or a stop, but fire right up? No one could figure it out with the stalling, but now its bad, started yesterday. Have white/blueish smoke sometimes, ( white smoke smells fuel) on restart after warmed when it dies, first time it took 25 mins to restart, now only takes 5 to 15 mins, when I step on it INCREDIBLE full power, fuel mileage gone to hell also since yesterday. Had full tank, now 1/2 tank.

No problems on cold start at all, no check light, 325,000 and never had this before.

Bad fuel?
ICP?
FICM?

Recent work, new turbo, ( turbo was original turbo installed when built) cooling line to waterpump, oil change, new fuel filters, front brakes and 2 new batteries.

Ford 6.0L Power Stroke Diesel :: 2005 - Rough Idle - Codes P0672 / P0674 / P0678

I have a 2005 f350 6.0 power stroke. I had a crank no start when hot issue. I bought an obd scanner with the torque app. IPR was at 85%. ICP pressure was low. I got the IPR out and bought a new screen because it was clogged. Upon putting in I broke the injector female side plastic connection.I bought the injector connector piece and installed it. After putting everything back together it starts but runs very rough,low power. The IPR was fixed. ICP,ipr and ficm are at good levels now.

IPR=14.7%-30%
Fcim sync=1.0
Fcim voltage=48.5
ICP pressure (idle)650-850psi

My fault codes are:

P0672 (glowplug)
P0674 (glowplug)
P0678 (glowplug).

Why it would be running/idle rough?

Ford 6.0L Power Stroke Diesel :: 2005 - Fuel Level Back Light And Oil Pressure Gauge Out?

The backlight for my fuel level and oil pressure dash gauges are out. Would that require a simple bulb replacement or if there is something more difficult to replace, i.e. entire panel? The red needles illuminate, it's just the gauges themselves that are dark. The truck is my 05 Super Duty in the siggy.
