Ford Super Duty (1999-2016) :: 2003 F250 V10 Never Dies Just Loses Power And Drops Truck To Idle
Jan 9, 2017
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.

I have a 2001 Ford F250 V10 with about 70,000 miles on it and now the gauge indicates low pressure when my warmed up truck idles around 1000 RPM.
I went off road the other day into some mud and since then I have had my oil pressure gauge reporting low at idle and normal when moving.
I was a quart and 1/2 low on oil which I filled and the next day I changed the oil. I then had taken it Ford shop who replaced the oil sensor and said all fixed. It wasn't and I took it back in ... now the mechanic indicated it is probably the crankshaft bearing based on his experience and I should replace the engine.
This seems drastic? Wouldnt' the next step to go check/replace the oil pump?

177,000 miles, fuel pump was replaced just before I purchased it a few weeks ago. Truck has been running like new until today when it started doing this completely out of the blue. If you watch the video, the sound is not off, the tach is moving independently of the sound of the actual revs. Occasionally when doing this, the fuel gauge drops to zero. Thinking this is an electrical issue somewhere.

I have a 2001 250 Super Duty. I am having an intermittent issue with the electrical system and transmission. I don't drive this vehicle very much so it sits for 7-14 days at a time.
Previously I had the od light flashing and had the transmission solenoid replaced. A few weeks ago I decided to drive it to the corner store. As I arrive home the od light starts flashing and the transmission starts shifting funny. I pull into my parking spot and turn the truck off. I sensed the shut off was weird so I tried to start the truck. NO POWER! None! I go back to the truck a few days later and it starts up without an issue.
Approx. 20 miles later it starts again. This time I have to jump the battery. I ran the truck and it drove without issue. Again a couple weeks later it starts in again with the light flashing and electrical dying. What it may be? I'm probably going to get rid of the truck as I can;t justify to myself to keep dumping money into it.

My husband and I bought a 09 f-250 with 58000 miles. It used to pull our travel trailer with no power issues. Now the rpms go up & the power goes down. It never gets hot nor any lights come on. It's been in the shop twice. The first time nothing was found. The second time we were told it was dirty fuel filters. The truck only has 70k miles...

Heard a 2011 F250 gaser while driving in the morning just falls flat on its face, almost like its starving for fuel as well as it feels like the tranny is slipping too. What this could be? I am not sure if its electrical or what.

The 2003 F250 5.4 Superduty has no power and keeps stalling. If I floor the gas it just stalls. I've replaced the pcv valve and line, the fuel pump relay, the fuel pump, and cleaned the tank, changed out the gas, added Lucas, and it just won't run right. Desperate, and no codes are coming up...

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?

I have a 2011 F250 with the 6.2 gas engine. I have been having a problem that the dealership says there is nothing they can do and have never heard about.
After the truck sits all night I get in and drive it for 10-15 min. It gets warm and I get out turning it off. When I come back about 15-45 min later I start it up and go to leave. As I pull out and start to accelerate in first gear the truck goes to an idle for about 2-3 seconds. I push the gas pedal and get no response. After a couple of seconds it picks up wherever you have the gas pedal. If you have the pedal to the floor it jumps you forward. This is not putting on any lights and the computer is not throwing any codes. According to the dealership the computer is telling them there is nothing wrong.
This has happened 12 times in the past 6 months. It has happened since I bought the truck. I have just started documenting it as of 6 months ago. It is not something I can make it do on command. After it happens once it doesn't seem to do it again for a week or two. I have 31000 miles on the truck. The dealership has had it for 4 days now and can't seem to get it to happen for them.

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.

I bought my 2015 in August of last year with 8K miles and here I sit at the dealership with 15K for the second time in 4 days.
Truck loses gauges while driving and throws all the warnings (tire pressure, temp, hill descent, and on and on). If I turn it off it won't start. I disconnected the battery first time it happened, about a month ago, and it restarted. Thursday it wouldn't start until the tow truck driver got it off the flatbed at the service center (go figure). This time I got it on video and parked it at the service center myself. I showed the foreman the video.
The service advisor told me it needed a software update last Friday when I picked it up, which is another way of saying they had no idea and didn't put much thought into it since it was running when they had it. The notes said they did a diagnostic, found no codes, and "drove it on a bumpy road" with no issues. Really?
This is extremely frustrating! I hope they actually do something this time. The damn thing started again before I left it with them!

2003 f250 crewcab 6.0 auto 4x4. I all of a sudden started feeling a vibration under the truck near the back when I accelerate and when I let off the gas no other time. No noises or clanking just vibration. I can wiggle the driveshaft inside the carrier bearing do you think that could be it or is it the rear end.

I have an 05 F250 Super Duty 6.0 V8 Turbo Diesel. This is my first diesel so don't know my way around it too much yet. I just don't know what could cause this problem. It sounds like a faulty sensor to me. But no engine light has come on. My oil pressure drops down to in the red zone when I brake while driving, then once I return to driving again it returns to the normal pressure. It's almost as if it has something to do with the tilt of the vehicle.

So I've been having this problem that sometimes when I am turning the truck dies. It doesn't stutter or anything it just shuts off and will start right back up. It doesn't do it all the time either. Was also having an issue where the windshield wipers would shut the truck off too. But I don't think that's the same problem.

Can get up to speed about 55-60 in my 2003 f250 6.0 4x4 truck and hit the brakes hard and the pedal gets hard almost like you cut the truck off and the truck doesn't stop well I can let off the pedal and hit it again hard and it works like it should. Also when it does this the power steering doesn't work. I was on an exit ramp and almost wrecked when I exited off the interstate I hit the brake pretty hard and couldn't steer I let off the brakes then hit them again and it worked fine and so did my steering. It would seem that the two are connected somehow. What's wrong?

I have a 2013 F550, v10. At idle, the oil pressure gauge drops and the red oil light comes on. If I hit the gas, the gauge pops back up. I swapped out the oil pressure switch. That didn't fix the problem.
I thought maybe the gauge was faulty, so I bought a 2 inch mechanical oil pressure gauge and hooked that up, leaving the factory gauge disconnected.
I watched the oil pressure start around 50 psi cold, and it slowly fell to 10-15 psi as it warmed up. The truck has 65k miles on it. There is no knocking, no ticking, no loss of performance.
I cannot imagine that at 65k miles, that it would be a worn engine. Right??

We have a lot of snow and a lot of ice up here at the moment and my 2003 ford F-250 SC Fx4 isn't performing so well. The truck is stock other than a pair of 285/16R BFG A/T's
I have been noticing that my rear tires will spin while trying to go up hill on some ice or snow covered areas and my front tires just sit still while in 4x4 or 4x4 low. In the case I just described I remain stuck in place until the rear tires can get a grip then I continue up hill. I don't understand why my front tires are not spinning as well, to me this seems just like 2 wheel drive not 4x4. I have been using ESOF most of the time. I have mentioned in other threads that I do plan on upgrading to warn premium hubs, but I am wondering if its that my truck isnt actually shifting into 4x4 or if there is a reason why even in 4x4 my rear tires would spin while my front tires do not?
I am confused because when I shift on the fly while driving I can feel the 4x4 kick in because it just feels different than driving with 2 wheel drive, but then something like I described will happen and I start second guessing myself. What might be happening? It's not that I am opposed to switching to the warn premium hubs, but is that actually going to fix this issue or is my truck acting normally??

While driving today, 2006 Ford F-250 5.4 L V8 138,000 miles , I experienced a problem. Started with the truck acting as if it was running rough, possibly missing. This was approx. 10 Minutes after starting. Checked the dash, no warning indicators and all gauges were normal. Approx. 4 more miles, the oil pressure alarm signals and I see the oil gauge has dropped to zero. I pull over, turn off and check the oil. Oil is clean and at a normal level. I restart the truck and the oil pressure goes back to normal.
Rev the truck up while sitting there and after a few seconds i hear a knocking noise in the engine and oil pressure drops again. Call the tow truck, driver used to be a mechanic . He asks me to start it again and the same thing happens. If you start it and let it idle oil pressure seems to go up to normal with no engine noise. Finally get to the mechanic and he calls me later saying the oil pump and screen may need to be replaced or the engine may need to be replaced.

Simple enough the truck starts then after about 30 seconds it bogs down and dies. I am getting these codes.
705 Transmission Range Sensor Out of Position
708 Transmission Range Sensor Circuit High Input
720 Output Speed Sensor Insufficient Input
743 Torque Converter Clutch Circuit
745 Pressure Control Solenoid Malfunction
1747 Electronic Pressure Control Solenoid A- Short Circuit
Sounds to me like the converter it locked up. What do you think? Its a 5.4L
