Ford 6.0L Power Stroke Diesel :: Fuel PSI Goes Down As Truck Heats Up
Apr 11, 2017
When I installed the blue spring kit I noticed that my fuel pressure would stay around 60-61 PSI. Since this was safe I changed my gauge info to display FICM. Anyway I decided I better go back and check on the Fuel PSI since it has been awhile since I checked. I started noticing that when I start my truck up in the morning my fuel pressure usually stays around 60-61 PSI. After it warms up sometimes it will hover around 55 PSI. Other times it will be back at the 60 PSI mark. Not sure if this is regular or not since I haven't been keeping long term track of what is going on. Truck runs great though, just wondering if maybe the fuel pump is getting weak. Also I have my sensor attached to the test port on the fuel bowl.

I was driving to a job this morning with my truck loaded with tile for a job and it just died.
It has power to the lights, radio, etc. But when I try to start it it does not even crank and it has no fuel pressure on the gauge and the pump is no running.
It is as if the truck has no power. When it died is was like I turned the key off and it just stopped.

I have a 2004 Ford F350 6.0. It is leaking diesel from the front of the engine to the ground. I have a video of this and pictures as well but I'm not sure what I'm looking at. What I can do??Puddle after about 20 min of running.
Dripping from here, left of hose....

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.

I have a friend with a 2012 F250. The truck has 100K miles and it does idle for extended periods. The other day his check engine light comes on so he took it the shop. They had not told him anything yet, but they did tell him that he had about a gallon to much oil. They said it was fuel.

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.

I have a 2005 f250 6.0 diesel. I have changed the 2 fuel filters, fuel pump, sending unit (was broke off in tank )and installed the blue spring fuel pressure regulator kit. My truck will run for a few minutes loose fuel and kill. Could this be a sensor or computer problem

So, I just had the fuel pump replaced on my '15 6.7 a month ago and it just died again. (next day edit: it didn't actually die, it showed all the same symptoms)
Same symptoms: whining sound, low fuel pressure warning, reduced power warning.
This time I'm 50 miles from home so I pulled off the road before it shut off. Interesting, I was in a hilly area and my low fuel warning came on too. We are waiting for a tow. I was considering trying to push on but don't want to get stuck in a dangerous spot on the highway. We're in a church parking lot.
So, last time this happened I was on flat road with about a half tank of fuel on a lunch break. I ran a mile after the warnings came on to feel out the issue and to see what would happen. I happened to be only about a mile away from my dealer so I drove that way. I got reduced power warning and then it cut power on me (limp mode). I made it to about 100 yards away before it cut off.
This time, I was in a hilly area at night on a windy two lane road with no shoulders in the woods. I was miles from civilization and was showing below a quarter tank of fuel. ~100 miles to EMPTY. I got the low fuel pressure warning first and then the reduced power mode before the whining noise started. I was climbing a hill on a curve at the time. I drove a quarter mile and then pulled off the road into a parking lot so I wouldn't be stuck on the shoulder. It didn't actually go into limp mode.
I let it sit a few minutes, talked it over with the wife and decided to call for a tow. After talking to the tow truck driver who said he would be an hour because he had to go find a bigger truck, I decided to see what I could do while I wait. I fired it back up and the fuel level dropped to below 1/8 and I was now showing 33 miles to EMPTY. I was parked on a hill with the back end up. I had backed the truck into a space to make it easier for the tow truck driver. I let it run a minute, checked for leaks and it seemed to run fine with no studdering or additional warning lights.
CEL was on but no new warnings. I put in my code reader and pulled the P0087. Just one code. I revved it a bit to see if there were any issues. It seemed fine so I decided to try my luck. I started driving towards home with the intention to stop at the first diesel station to fill up. Truck ran fine. After two minutes of driving gently, heart racing, my fuel level came back up and it now read 88 miles to EMPTY. I drove 11 miles to the nearest station and filled up. No issues. I shut it down. I fired it back up. Still no issues so with a full tank, I drove home the remaining 30 miles without issue.
Planning to take it in to the dealer Monday to get it checked. Could this be from an air pocked due to low fuel level and hilly terrain? Is my new pump dying already? Is there something else going on inside the tank or elsewhere?

I have my aux fuel tank pump hooked to upfitter 3. It has worked perfectly until this week. I started to transfer fuel and the aux fuel gauge and fuel pump both quit. The led on upfitter switch 3 still illuminates, but no fuel pump. I found fuse 9 on passengers kick panel is for upfitter 3. The fuse was good. Is there another fuse somewhere for the circuit I've missed? I can trouble shoot the wiring if necessary, but it's tough to do all behind the left side underbed box and not easy to get to. I've missed something simple before I go further????

I have a 2006 F250 c/c LB and I am curious, how much fuel is left in the tank when the low fuel light comes on?

For the last four months my 04 F350 has been having the same problem every now and then. Cruising down the highway at a decent speed and the fuel pedal/fuel shuts off. Only lasts seconds then re-engages. Two lights come on. Low fuel and water in fuel. I changed the internal fuel pump last week and it did it again tonight. The truck runs great otherwise except for an occasional death shake while stopped at a light. No codes came up and FICM is at 54.

Changed fuel filters today. Now my water in fuel light is coming on. But the truck is not running any different no sputtering or anything. ????? Could this be human error

I have a very slow fuel drip off the housing for the fuel filter on the engine. Can't see where it's coming from. It started sometime after I changed the filter a couple of months ago.

Purchased 2011 3 weeks ago. Due to not paying attention, put gas in diesel. Had tank dropped and drained but after reassembly, fuel gauge inop. When turn ignition switch on, get normal sweep of all dash gauges but fuel gauge does not read. 2nd tech says sender okay, must be gauge. Dealer ssays if it sweeps, it isn't the gauge. 011 F250 6.7L.....

no change, changed stand pipe and dummy plug on driver side, no change and guess what? Now I am stuck on the side of the road waiting to give my last $100 to a tow truck! Engine is hydrolocked, fuel pressure is low, starts off at around 20 and works up to 54 with key on engine off, and that is as much as I know from the side of the road with out my AE. Blew white smoke also. Smelled of unburnt diesel. I think it's linked to my rough running issue. Maybe a bad injector? But every time I did the click test they all passed. Idk, I'm gonna remove the glow plugs and see which hole is loaded and with what. . .

Jumped in the 1999 cc dually 7.3 6 spd superduty.
Just rebuilt the rear locker ( FYI if you use new clutches Do NOT add clutches, it is TOO tight now) and rest of rear end.
Full of fuel, drove it half the day only minor issues. Cruise, Horn, 4x4, suddenly would not work, but it was running and driving like it always has.
Around lunch while at 55 mph it shuttered hard like it had stalled for a second. I stopped and checked the oil. It was just above the add but I topped it off and went one. The further I went the more it happened.
So I decided to head back to shop and switch it with the car i had left there. It finally died like it was out of fuel.
next day I take 5 gallons of fuel and put in it ( maybe the gauge is acting up like the horn, cruise and 4x4?), it brings it from 3/4 plus to full mark, so gauge is working accurate. I also keep a fuel log that says i went 100 miles since last fill up.
Get in, it fires right up. I leave it sit and idle while i park the car. About 5 minutes and it dies. It will start run a few seconds and die again. The more I try it the shorter time it runs.
Finally does not want it start at all. I read about disconnecting plug on inside left front of valve cover , that had not effect. Crawled under, and frame mounted fuel pump is running.

My 6.0 with 178k on it just started to have issues today. Low power. When I hit the pedal hard the motor revs and the truck barley moves. When I baby it it goes up to speed and shifts fine. Overall lacking power and not going anywhere. No CEL on. Turbo spools and seems to be ok.

First post since I bought my powerstroke. I was looking for some diagnostics.
On my way to work this morning and the truck started chugging like it was wanting to die and had no power, the pedal was to the floor and I was barely moving. I was able to nurse it to a parking space at work and pulled the codes, using the Torque pro. This was what I pulled:
P0284 - Cylinder #8 contribution/balance
P0299 - Underboost
P0611 - FICM
P0401 - EGR
P0671 - Cylinder 1 glow plug
On the way home I didn't even hit 5 miles and started into the same symptoms. So I decided to call for a tow, because my commute is about 60 miles one way. In waiting for the tow truck I disconnected the batteries and reconnected them thinking that it might "reset" something. I started it up and the same thing occurred, so I tried revving it up, and starting it up and shutting it down on and off for about an hour. Thinking I picked up some bad fuel. Drove it for a short distance and found things were getting better. I was able to make it home and pulled the codes again. It came up with these:
P0284
P0603 - Internal Control Mod.
P0611
P1000
Also on the ride home I had excessive amounts of black smoke from the exhaust and found a couple of large drops of oil on the driveway where i normally park, larger than what I normally see.
So my question would be what is the cause of all of this?
A little about the truck. it is a F250 CCSB with about 139xxx miles on the clock. I bought it from my brother when he had it he had the FICM replaced (with the 58V option) and the Bullet proof EGR installed. I replaced the fuel spring with the blue one shortly after I bought it.
