Ford 6.0L Power Stroke Diesel :: No Power To Fuel Pump
Apr 9, 2016
2004 F-250 4x4 6.0 diesel 120,000 miles, only modification is egr delete, i had a loss of power, pulled over truck died, replaced both fuel filters, found pump was not running, checked and had power to pump plug, replaced fuel pump, now no power to fuel pump, have power to fuse (40 i think) have power to inertia switch both sides, but no power to plug at pump. ran jumper wire to battery to get truck home. I need to know if there is any other component between inertia switch and pump, and or test points, as i think i must have a broken wire.

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?

So I'm stumped I have an 04 6 liter and I have no power to my fuel pump. My fuse under my Dash is good which is a 20 amp fuse which is number 40. My inertia switch is not tripped and I have power to it however my fuel pump does not have power what else could it be? Is there a relay somewhere else?

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????

So I just replaced the low pressure fuel pump on my 14 6.7 and it seems to be running as good as it was before. I need to get an aftermarket fuel filter setup for my truck. So what are you using, why did you pick that particular system and is it working, does it really work for taking out water and other contaminates? These fuel systems don't seem to be up to par in filtering modern day fuel, I need peace of mind.

After filling up today at the pump, the low fuel message is still coming on. My gauge is correct though. How to clear the message. I keep on trying to reset it with the reset button but it doesn't go away.

I am a new diesel owner. I bought a 2014 F250 about 9 months ago. Three times in the last 50k miles I have heard the fuel pump near the tank making noise. Twice, while making the high pitched noise I have gotten a low fuel pressure warning and reduced engine power.
The first time, I left the truck with the dealer for two days while a tech drove it around. everything checked out fine. (30k miles)
The second time I heard the noise i did not get the low fuel pressure warning. (40k miles)
Today, I heard the noise and got the lower fuel pressure warning just before the truck stalled out. Lucky for me, I was near home. After a minute the truck start and I nursed it the last mile or two. (56k miles)
The tow truck just picked it up and is off to the dealer. It sound to me like the low pressure transfer pump is bad or going bad.

This pump hangs down fairly low and appears easy for ice and rocks to hit on my 2013. Something hit mine and took a chunk out of the drain tube. No leaks yet but I am looking to get a new one and keep this as a spare, or just JB weld it. Can I just buy the lower section, or do I need to get entire pump?
Any creative protection bracket made? Would just have to take it off to change filter though. Any leak in this housing is a major show stopper when in the middle of nowhere! Maybe why it is getting brought into the tank on new models?

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.

I just recently bought a 2011 powerstroke f250 and while running I can hear the fuel pump humming pretty loud. Is this a possibility that it's going out? Or is this normal?

Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I figured 200 dollars cheaper than taking to ford....
I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good.

Recently my 2011 F-250 Diesel with 21,000 miles seemed to start hard one morning. After starting the truck it ran well that day and started fine. The next morning it would not start. Had it taken to the dealer and they went to work. Started at the fuel filters and replaced low pressure fuel pump. Thought a piece of the defective pump had moved up fuel line. Removed high pressure pump and found signs of rust. All regular service intervals have been met. Didn't see this coming. No water in fuel light or other warning.

2003 F-350 - 7.3. With the key in the on position there is zero voltage to the fuel pump. Fuel pump fuse is good. I traced the red with black tracer wire from the pump up through the firewall and to the safety inertia switch. The switch has continuity so it's OK. Then from the safety switch I traced the green with yellow tracer wire to a fuse block plug connector. Then I checked continuity from that connector out to the #40 fuel pump fuse and it's open.
So I then i checked from the fuel pump fuse to all the back connections on the back of the fuse block and there was no continuity to any of them. So I removed the back cover off the fuse block to expose any issues. I found two board mounted relays. Now, from the fuse I get continuity to one of the relay connections. So did Ford hide the fuel pump relay and make it non replaceable? Also if this is the pump relay then what circuit energizes it? I need to make sure before I replace the fuse block.

I have a 2003 F250 and dont have power at fuel pump, or fuse #30. I put power directly to fuel pump and it worked and truck fired right up.

When replacing the power steering pump on my 2006 should I go OEM on the pump or save some money and get a Napa or aftermarket remaned unit with the pulley installed? Also, whar is the fluid capacity of the power steering system?

I am having a heck of a time finding this coolant leak. It drips off the power steering pump. I replaced the upper radiator hose and the heater "y" hose that goes to the bottom of the Degas bottle. I recently replaced the lower radiator hose as well. So the truck runs normal. When the system is under pressure I do not see any leaks. But after the engine is completely cold it starts leaking a small puddle of coolant. Its appears to be coming from the power steering pump. But I am sure its something above or near it. This is on my 2005 Excursion with a 6.0. Can the water pump be going bad and leaking this direction. I would expect a water pump to leak straight down the middle of the engine. What to look for? The thermostat seal stays dry. but it has to be in that area. What is really messing with me is. When it is hot and pressured up It does not seem to leak. Only after it has been sitting for hours and cools off..........What the heck!

My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

Checked all fuses in fuse box, any other fuses or relays. The pump works when I jump it with a 12volt battery, so I know its good!

01 7.3. Cranks, won't start. Tank was at 1/4 but is full now. The lift pump runs, I can feel and hear that the motor is spinning when I cycle the key. I removed the fuel filter and cycled the key and get no fuel into the bowl. It looks like the lines are stainless from the pump to the tank so I doubt it is sucking air. I pressurized the tank with a shop vac and I get fuel coming into the filter housing. Am I missing something obvious? I have never seen an electric pump that would run and not pump fuel. I removed the suction line at the pump and don't feel any suction there.
