Ford Super Duty (1999-2016) :: 2001 F250 V10 - Sudden Power Loss And Dies Randomly
Dec 14, 2015
I have a 2001 f250 super duty extended cab with the v10. Over the past week it has been running fine and it will all of a sudden lose power and dies. I've been able to start it back up once right away and a few times it started up after a few hours of messing with it.
So, after the truck dies it will crank and crank but will not start. We have checked fuel pressure and nothing. Then we applied direct current to the fuel pump and it turns on. Then we applied direct current to the fuel pump slot in the fuse box and got a fuel pressure reading of 40 psi. But when we crank we have no pressure.
When we apply direct current to the fuel pump slot in the fuse box the truck will only crank and not start.

On the highway doing 100 mph. during af take over, my Ford F-250 6,4 Super Duty 2008, lost nearly all power. (now it is like driving my old hummer h1)
Engine and car runs/starts great, only 10 minutes uptil 60 mph. now.
My mechanic has given up. He checked following:
EGR = OK
HOSES = OK
ERROR CODES = NONE
INTER COOLER = OK
PARTICLE FILTER CLEAN = OK
TEST WITHOUT EXHAUST = NO DIFFERENCE
FLUIDS = OK
Hopefully something I can fix with my hammer. The car has 85.000 miles on the clock.

My excursion suddenly lost power after sitting in a long traffic jam. I have a scan gauge II set up and didn't see any signs of over heating however when I went to accelerate back up to highway speed my motor revved up to 3000 rpm and just lost power I ended creeping on the side of the road at about 15 mph and barely maintaining that. The motor was not willing to revv up. I reached a spot to pull over and shut it down for about 15 minutes and started back up and drove off with no noticable issues. I have 211,000 miles on this motor and I am going to change my coil packs, I think they have been there since the truck was sold new....I changed four of them to address a miss and have six left, I will also be changing my fuel filter. We are about to pull our camper across country....about 1400 miles..

My 2010 F250 V10 120000 mile has a sudden loss of MPG. It usually is around 12 MPG but now I'm at 8 I checked the air filter and its clean I checked the tire pressure and there all up to pressure. I'm probably going to try the fuel filter next.

Last night was getting down to freezing. I drove out of my buddy's driveway, stopped to close the gate behind me, put it in gear and started to drive away, about 5-10mph. I left off the gas as I rounded a gentle curve, then got back on the pedal as I exited the curve. All I got was a revving engine, as if I was in neutral. Checked to make sure I was in gear, and same result. I stopped, engine running, and put it in park, and then back into gear. Nothing. Drive, low, Reverse nothing. I did see the rpm change slightly. engine runs normally.
No fluid loss, no mechanical noises indicating something breaking. No weird smells. Fluid level is as good as I could read on that crappy trans dipstick. Truck ran flawlessly up until that moment. the transmission is a BTS with about 100K, so I'm fairly certain it's not the mechanical diode notorious for that year. My problem description does not seem to fit the failed diode anyway. I did run across a post that better matched my problem description and that was the transfer case motor. I have 4WD, but was not in 4WD at the time.

I am trying to diagnose a problem with a friends 2002 f350 7.3L truck. the engine has approx. 140,000 miles and is all stock, no programming or aftermarket parts. Anyhow, he said driving down the road the other day the engine all of a sudden lost power and the truck wouldn't go any faster than 45mph. he said taking off from a stop sign, the truck has no power and takes forever to get up to 45mph. after this issue began, he has changed the fuel filter & screen, air filter and fuel pump. The check engine light if OFF, no active fault codes.

My 2002 F250 7.3 randomly dies while driving and seems to only be when I hit a bump no matter the size. I have checked the valve cover harness connector outside of the valve covers and they look fine. I checked the ECM connection took it off and reconnected it.
Changed the CPS censor twice, checked the ICP sensor, checked continuity of all the glow plugs through the valve cover harness. Checked the fuel pump, checked all related fuses, changed the fuel filter, checked glow plug relay, batteries hold good voltage and were recently upgraded to bigger batteries.
Engine runs just a little rough but not enough to be of concern. Air filter is clean and oil level is perfect. What could possible be causing my truck to randomly die when it hits a bump and not start back right away??? This truck is new to me and its the first diesel engine I have ever owned.

I have a 2001 f250 superduty 7.3L diesel and my air conditioner just randomly started blowing HOT south texas air. I tried to recharge it with refrigerant but the gauge said that it was over charged as soon as I plugged it into the low side port. What is wrong???

2001 F250. My drivers side seat belt buckle randomly releases and it's getting worse. Any sources on a new one or used even. Also, what other vehicles may have the same part number if I go used.

One of my work trucks is a 99 F-250 5.4L. Up until recently it's been running strong. Then one day it's like someone flipped a switch, and now it runs like it's losing power.
Symptoms: a quick short stumble when you first hit the accelerator. While driving, it takes the entire pedal to accelerate. Even with the pedal to the floor, it won't keep up with traffic. Driving uphill, it will barely maintain 40 mph.
I've checked everything I can think of. Fluids and filters are all good. Battery and alternator are good. There are no trouble codes. I have Autoenginuity with the Ford Bundle, and the truck passes every diagnostic test I throw at it.
There's no smoke. It still idles pretty smooth, although there is a slight and very quick random shudder in the idle that has started at the same time it started losing power.
Transmission is good. The last thing I tried was to change the fuel filter, but that made zero difference. Quick question, does the tank on the 5.4L trucks have a pickup screen like the diesels? If so, I might try blowing some compressed air through the fuel line and see if it dislodges anything.
So that's where I'm at. It has no power, yet I can't find a single thing wrong with it.

I have a 99 F-250SD with 5.4 automatic that just all of a sudden started running unevenly at random times, but frequently. There is a pending code P0300 Random/multiple cylinder misfire. I have had the truck for 12 years and it has run perfectly for the last 10+ years and just started this problem, it did not come on slowly but all of a sudden. I have seen on here that some people say that 90% of the time a PO300 is a bad cop. I replaced the plugs 60k miles ago when I had a bad coil on plug 10 years ago that did not set any codes, but this seems very different that more than one cylinder seems affected, like maybe 2 or more cylinders are not firing momentarily.
There is a big power loss momentarily while it happens, but doesn't happen for long. The fuel pressure stays pretty constant (30 psi at rail) even while it happens, and it can affect the idle as well as while accelerating or cruising at speed. I cant imagine more than one coil on plug would be skipping at the same times or fail at the exact same time, but maybe having only one bad cop could cause this much hesitation? Does the code that indicates random/multiple cylinder misfire rule out only one bad cop? It just seems like running on 7 cylinders wouldn't be so noticeable. Could a sticking egr valve cause unevenness at idle and higher rpms and set a P0300 code? Would checking manifold vacuum be they way to see if egr valve is not working correctly.

I have a 2004 F250 Super duty that had a battery die (I left the keys in the ignition switched on overnight) and after jumping the battery off the vehicle started up but now I have no power door lock or window functions. Any reason a dead battery issue might affect the power locks and windows?

When passing or going up small inclines on freeway, my F250 seems to make the shift to the passing gear but then almost a complete loss of power. Jerks around for a few seconds and finally provides enough power to at least get back to the original speed. (It feels kind of like the lurching, etc. I used to get when those stinking GM diesel injectors would act up in the 1990's.)
It also stays in first/second as I punch it while entering the freeway and doesn't want to make the shift. I can put it in neutral and race the engine, so I don't think it is an engine problem, unless the transmission is electronically controlled. I have a lot of computer dashboard gauge resets after falling to zero and sometimes have to set and release the parking brake to get the auto door locks and windows to work. (That started after a car break in where the door electronics were apparently pinched, but that was a couple of years ago.)
Does it sound like the transmission or electronics? In the old days replacing an automatic transmission filter seemed to fix a lot of transmission issues. Not an option now, but would I expect to see any results doing a transmission flush and fluid change? It's probably been about 60000 since I had that done. (157000 now).

I have a 1999 f250 super duty with the 5.4 Triton motor with a 5 speed. I bought the truck a couple months ago, and it had a bad manifold leak (not surprised lol). but it ran fine just noisy. So i had a shop do new gaskets and bolts. Then my problems started.........
When you start up the truck she runs fine and some times drives fine. I will be driving along and its like some one hits a switch and i suddenly loose all power it spits and sputters and i have to down shift to make any kind of hill.
So I figures I had a misfire i got a light on for cylinder 5. So I decided to change all coils and plugs hoping that would clear things up...... well it didn't. It ran great for roughly 15 miles then it started to do the same thing again. I've changed air filter and fuel filter also.
When it starts sputtering i sometimes get a check engine light on and then it goes away. when the light is on the codes are:
P1151 A Heated Exhaust Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

P1152 Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2
Read more: P1152 FORD Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Rich Bank 2 | AutoCodes
Both codes come on together always. but it will go away when the sputtering clears up. I just checked fuel pressure its at 32psi at a idle.

Got a 2001 7.3 crew cab long bed over the winter and over the last week I have some electrical issues.
Leaving work I had a dead battery(s) or so I though. first though the batteries are going or the alternator going. Its a manual so i had a friend pull me to bump start it and everything was as it should. The volt gauge came right up and checked the alternator and it was OK.
Later on while driving the radio turned off and I could not get it to turn back on. At the time I didn't notice if the other cabin accessories were working
(didn't think to take notice). So, turned around a drove straight home. Once in my drive way I shut the truck off and right away turned it back on and the radio came back. I didn't know what to make of it so I just let it be.
The next morning I went to start the truck, Wait to start light went out and when I turned the key. Just a click. and the instrument panel goes dead along with all the other cabin power. when i open the door the turn signal starts clicking. So I took the batteries out (thinking that something is staying on inside the cabin and draining the batteries). I charged them at work came to find that they are holding a charge.
My issue was most definitely the GEM. So i took that out sent it to Florida and got it serviced. When got it back today and ........Same thing. I am at a loss here. Am in looking at the right things? What should I be looking for?

I have a question for everyone out there with any insight of the harsh shifting with these trucks. I have a 2003 f250 super duty with the 5.4l and 126,000 miles on it. The problem I'm having is some weird shifting that has been going on over the last six months and I feel like I am just throwing money at this problem. My truck shifts hard from 2nd to 3rd and from 3rd to 4th with the most violent shifts being from 3rd to 4th! Between shifts is where it Is sluggish I mean if I am not on the throttle from those shift points I switch from driving a truck to a geo metro it is night and day with the felling of loss of power!
I have had it scanned at my local ford dealership and had a full diagnostics done and all I got was "it's since truck and a nice bill to come with it" they couldn't find a thing. So far I have all new motorcraft plugs, cops, changed fuel filter, had my catalytic converter checked if it was clogged,run on two different power balance tests! Still nothing! So now I'm lost I have heard things about these trannys and the lock up but I was told this only had to do with overdrive and it wouldn't happen at other gear changes. I still drive it everyday I have just figured out ways to calm it down if I stay off the gas when it's about to shift for a couple seconds then get back on the gas it is like it never happened.

We have replaced 4 fuel pumps on a row.
Voltage is good...even ran a fresh circuit.
Ran new supply lines
But, can't seem to understand the continued drop in pressure. It usually takes about a day of driving to crater after a new pump/filter is installed.
It never dies, just loses power and drops the truck to an idle. Funny thing...if I shut the truck off and turn it right back on...full power for a short period!
The truck is used on a ranch that has plenty of rough roads...thought inertia switch maybe but i believe that would stop fuel completely right?
I am totally stumped and so is the mechanic.

My truck is a 2003 f250 / 2wd automatic, 7.3 powerstroke, 284000 well maintained miles.
Just last week I sprug a large oil leak and had to replace the hoop outlet o rings..problem solved. This week I can drive 15-20 miles on the freeway and the truck starts to act like ota running out of fuel. Bogs down to 40mph then starts missing. I pull over, and when revving I have un burnt fuel and oil smoking out of my tailpipe. I let it sit for 5-10 minutes and it will be fine for the rest of the drive and this happens intermittently, there is no pattern.
The truck has a ton of power, starts great hot or cold. I did a ton of research and found a IPR could possibly cause this, as could plugged screens in the fuel pickup. Then I read about all the injector harness issues but I don't think that I my issue.

Cruise won't power up. Tried entering diagnostics but did not get any flashes. By-passed switch on master cylinder, did not make any difference. Horn honks. Brake lights work correctly.

1999 f250 5.4L... Its done this 3 or 4 times now. Driving and it starts pulling to the right pretty bad, almost like if the front passenger tire was messed up or something. Today it did it, after I let it sit for a few min, then drove back to the house, it drove straight. Also, when it pulls to the right, its very sluggish, as if I'm pulling a very heavy load. From a stop, it doesn't even go until I hit the gas, and at that its very sluggish, sorts feels like if you drive off and forget the ebrake is on.
Also I've noticed some burning on the passenger side which I've read is probably the head gasket. I can see the oil dripping on the exhaust, causing the smoke. Also, my CEL just came on, with code P0401 "powertrain exhaust gas recirculation flow insufficient detected". Recently changed the plugs because it was running and idling a little rough.
At this point in wondering if the pulling issue could be something with the brakes, when I'm driving, it sounds like something is rubbing, I haven't looked at the brakes yet but I'm likely going to do new pads and rotors all around soon anyways.

I have an 03 f250 5.4l that I've been having some problems with. When the engine is cold it will drive fine and everything. When it warms up, if I go to put it in gear it just dies right away. Why?
