Ford 7.3L Power Stroke (1999-2003) :: Truck Was Shutting Off While Driving
Dec 21, 2015
Last week the engine in my truck was shutting off while driving. Happened to me 3 times over the course of two days. The first couple of times, the engine was dead for 3-5 seconds and then the engine would come alive and drive normally again. The third time was about a 10 second event...same result, engine refired on it's own and drove normally. I was in motion all three times so the engine restarts all occurred before I was able to bring the truck to a complete stop.
No check engine light...(I didn't pull any codes because I didn't have my laptop with me). So, I decided to try a new CPS. I had one in my glove box since 2003 so in it went. It replaced a black CPS that I purchased from Riffraff about 100k miles ago. The new CPS seems to have done the trick. I've driven about 500 miles since the swap and the symptom has not returned. I wonder how long this one will last. It's a Ford replacement part so maybe I'll get another 100k miles...

So I have this intermittent problem of the truck shutting down on its own when in idle or idling along in drive I immediately put the truck in N, turn the key and she starts right up again.
Does not do it at speeds, just in idle. The "check gage" and "battery" light are the only dash lights on after a shut down.
Where do I start?

I have a little problem with my 1999 f250 7.3 power stroke diesel. Every once in awhile, while driving the truck would die completely but i switch it into neutral and started right up. What could be the problem?

I have a 2001 F350 7.3l diesel.
My truck died the other day while driving almost like he ran out of fuel. Well he had fuel so I checked the oil and it was dry. There was an ugly puddle between the intakes and a whole lot on the ground leaking out. Also the puddle looked blueish.
Put in more oil and got him home but I can't find the leak. The only thing I've noticed is that the intercooler on the cold side came off slightly. A year ago I had to go mess with the UCVH and when I put it back together I had lost a dang intercooler duct clamp and replaced it with a sturdy ring clamp. Well it wasn't sturdy enough.
How much would this leak if it came off for a little while and how serious of a problem would I have as a result? I don't have any check engine light and as long as he has oil he runs fine.
Since I have reconnected the intercooler and idle tested the truck I can't reproduce the leak. I don't believe that a huge amount of oil is running through that intercooler because the turbo is lubricated through another system I have read. So what gives?
Also I am getting weird dip stick reading. For a little while when I ran the truck today he was showing WAY over full on the dip and then down again a little bit below the operating range line. Also there are a lot of air bubbles on the dip stick when it comes up. Way more than I am used to seeing.
Also, I really like the idea of cleaning my engine off really good. It's a frigging mess now. What precautions can I take to clean it up good without making a huge mess. Can I just go the car wash that has a degreaser hose and drain and just spray it down like nothing or is it sensitive and finnicky when wet? Cleaning between the intakes seems almost impossible without getting the whole turbo system out of the way. Should I be thinking about that?

My wife returned home and stated that my excursion stopped running twice while she was driving it. She said both times were as she was letting off the throttle coming downhill an off ramp. Both times it fired right up and drove away fine.
I pulled the codes using torque app and it showed a p1211. Unfortunately I had just screwed up my gauge settings so I really didn't have any gauges set up so I couldn't use it. (It's for the 6.0 anyway).
After some Internet searching I am guessing it's an issue with the icp or ipr. How do I tell which one to replace? Truck does have a dp tuner normally set to 80 economy tune.

Like the title says my truck has been stalling while driving. Accelerating or cruising it dies for a second, two at the most, and then just keeps chugging along again.
I thought i'd fixed the problem last year when I did injector O-rings and 50 cented my UVCH. It hadn't done it since, until two days ago. Started out with a two good solid stalls while gently accelerating up hill. I had thought maybe my fuel pickup foot had finely given up the ghost because I was below a quarter tank. But I filled her up full, and then she did it again about 50 miles of driving later.
I didn't catch the first four stalls on my torque app, because I'd just recently decided to stop logging every trip, with the thinking that it had been half a year problem free, why keep logging waiting for something that isn't going to happen. I did catch the 5th stall on the torque log. But I'm having trouble trying to figure out where it happened in a 30 min log.
First question where would yall start in tracking this thing down? Next what data actually should be logged? I think I've got some extra stuff in my logs that isn't necessary, and is maybe bogging down the system. I get one data point per second resolution on my logs. Are there ways to improve the resolution, will getting rid of some PIDs work?
Lastly I need to attack this thing smartly, without throwing time and money at unneeded parts. I had surgery and I've been out of work for 3 months and I'm looking at another 6 before I'm making money again, and there is no unemployment for the self employed. Also I only get 3-4 light weight upright hours a day to work, exceed that and I'm back on the couch battling swelling for a week.
Also is there anything I can do while driving to "flag" the stalls so I can find them more easily in the logs?

Driving home sitting in traffic slow moving 5mph, truck shut down
Able to start up about 5mins later
3rd Time
Replaced CPS, Air filter, Fuel Filter
Outside Temp: 80
Hauling travel trailer up peak 35-45mph shut down
Allowed truck to sit 35-45mins started back up

I have a 2000 F250 superduty crew cab short box. It has any occasional issue of either just shutting down (engine dies) which seems to happen if i hit an occasional bump. The other issue has happened a couple of times which is it will lose power and just go to a rough idle. I shut it off and restart it and it will run fine. I'm wondering if it is the throttle position sensor.

My 6.0 powerstroke keeps shutting off when I hit a bump. It's like everything died and reset and I loose all memory to stereo and everything. When I got to work and popped the hood I tapped on the battery cover by the pcm and it shut off again.

I have a 03 F250 5.4 4x4 auto, last year I had a problem with the truck shutting off randomly. So after doing all the dumb stuff and research I ended up concluding that the FP relay was acting up and my understanding is that, it is located in the fuse block. So not wanting to replace it I wired up my own relay next to the safety switch in the passenger side kick panel and it has been fine ever since. I did put a new pump in it (Cali emissions) Now to present day-
Over the past month my truck would have a slight hesitation problem when accelerating on the highway/up grade. The issue was it would go away for a while when you would shut the truck off and be good for a while. Well then it started happening all the time.
I knew I was do for a tune up (215,000) so I did all the plugs, COP's, fuel filter and a PM. It got a lot better but was still there at the top end. So after doing a lot of research I found a lot of people having the same issues, so for testing purposes I cut the CAT out and installed a section of flex pipe. (Iwill be installing the cat back in)
So last night I take it out and its even worse...I went don to my buddy's place and hooked up a Versus and got no codes at all, no misfires on the counter..absolutely nothing. So I did what I should have done in the beginning and duct taped a fuel pressure gauge to the windshield and took off.
At idle I have 30 or so PSI, and when it was fine it would stay around that, when it started acting up it would drop to 5-2psi under load and go back to 30 or so PSI at idle. The other thing is now I only have 1/4 tank of gas.
What I am concluding is that the pump is getting hot and weak, because when I had a full fuel tank it was better and now I have less fuel to cool the pump and it is happening faster. Should I just throw another new pump in it? Or go after a voltage problem to the pump?

I am working on an 2003 F-250 6.0l. The truck just died while driving. No restart. Plugged in my scan tool and I am not getting any High pressure oil. Is there anything other than the Hpop I should be looking at. I know it is a big job to replace the hpop so I don't want to overlook something simple.

I have a 2003 7.3. Suddenly a week ago when I left work, I noticed my truck wasn't picking up much, but i was in a 40mph zone. I then jumped on the freeway and noticed the truck would not go over 60mph. Once I exited and got on another road with a 55mph speed limit, the truck would not go over 45mph, I had the pedal pressed all the way down and would not go over 2000 rpms. Also, for the transmission to shift, I would have to let off the accelerator.

I have a e99 f350 7.3 all stock. I have no power. The truck will crank for about 15-20sec before it'll turn over. I just purchased the*AE*but am fairly new to understanding it all. In idle its a little rough and when I drive I can only stay in the neighborhood because of fear of getting rearended due to very slow acceleration. Whats weird is that when i have no power while i am driving ill keep the pedal down throw it in nuetral and my rpms and*icp*pressure jump up right away. Things I've replaced:
Icp*sensor
Fuel pump
Pcm
Tps
Cps
Ipr
Dropped tanked and cleaned screens
When cranking my*icp*pressure climbs slowly to right under 500. I dont know what else to do ive been working on this truck dor two months some days 13hs straight, I am feeling defeated. Codes p1249 1211 1209....

2002 f250 7.3l diesel...
I got a new radiator and the tranny fluid was the worst the mechanic had ever seen. He serviced it and warned me that it might not be long for this world. I broke my flexplate and so I had to pull the tranny, and I decided to throw a new torque converter in because it was giving g me symptoms like a broken sprag( it wouldn't rev up or do a brake stand in gear, therefore slow takeoffs).
I was recommended to replace the tranny, I decided I could do the job again down the road if I needed to. About two thousand miles down the road I had a hard shift going from overdrive down to get up a hill and about 10 miles later the truck started slowing down....I couldn't give it enough pedal to keep it going and the engine sounded rough.
I pulled over and checked fluids and everything was fine, truck idled fine, bright red tranny fluid not burnt at all. Pulled on to the road again and it pulled fine until about 40 mph and it wouldn't go any faster. I got it towed home and ordered up a tranny from Ford figuring it must be toast, but I thought I'd throw it out to the forum to see if there is any other troubleshooting I can do before I install the new one in case it is some other problem or some electrical harness or something, or if that is a pretty standard reaction to a fried tranny.
Engine runs good at idle, shifts perfectly to drive and reverse, drives forward and back(I'm very hesitant to drive it out of the driveway in case I can't get it back in). Only happened two times before I decided to tow it. Temps looked fine on the gauges, fluid was a little overfilled in the tranny, but again, not hot or burnt.

Problem started 2 days ago, driving around and my truck would stumble and lose power. Give it gas, won't rev up but it cleared and ran fine for a mile or so then it comes back (off and on all the way home). Check engine light didn't come on the first few times, came on a couple times on the way home (maybe 4 mile trip) but goes off when the truck runs fine. Thinking it was maybe the fuel pump (got 140K on the stocker). Talked to a few friends, some thought it was algae build up in the tank that was clogging the filter on the pump, underhood filter changed a couple hundred miles ago. Looked fine with slight brown build up at bottom of bowl when I replaced it.
Ran it around yesterday with a friend of mine and his scan tool hooked up, acted up once, check engine came on for a few seconds and shutoff. No code and for some reason we couldn't get it to live data while driving. I dumped in an algae eater yesterday and left the truck overnight since I had to work. Got home this morning to run her around the block to circulate the eater. Truck started and idled fine, went to pull out and she won't rev up, pumped the gas and NOTHING! Check engine light is on now but don't have a scan tool handy to read it. I heard the truck will store the code?
What this problem might be? What's a good scan tool for our trucks that can live data as well? CPS is good and already did the UVCH mod.

My truck runs very rough and lacks power when cold, even during the Texas summer. Once it warms-up, everything is fine. It's almost like turning on a light switch. If it's plugged in for a couple/few hours, it's smooth as soon as it starts. I'm assuming it likes the oil once it reaches a specific temperature. What my problem is?

I want test my fuel pressure. What is a good gauge or kit to buy? My truck has lost power towing and is now starting to miss a little. I'm wandering if i my problem is in the tank. Is there a good scan tool that would diagnose things too?

I have a 2003 Excursion 6.0 with edge juice with attitude
While driving first thing in the morning runs like a champ, as the engine warms up I start seeing the exhaust temps lower to 88-94, then I start getting over boost code with monitor reading of 41psi, then the Edge monitor screen will go blank, then the STALL... The excursion with start right back up but the shut off immediately. Wait 20-30 minutes in the shade and will start back up and run again poorly missing almost like turning the key off and back on... Then the next morning start all over again.
I'm thinking bad FICM or bad PMC over heating.. ??

So long story short I have a 99 f250 xl, 7.3 130k. Overall good truck but has no options, never had AC but would like to add it. I have seen the kits on bought4less. So I'm thinking all the factory parts should be bolt on, since the holes should be all there, and since most of the wiring should be there. I just need to collect all the parts. Also one question I have is, what goes through the firewall. Is it just the lines, or how does the ac get to the vents? Dumb question but don't get that part of it.

Started truck 3 times in 30 min. no issues with truck before tonight nice well cared for truck. Went to get a pack of buns at store came out --NO CRANK--all lights are on dash, etc, new starter a month ago, relay changed out in fuse panel just to see if there was a change. Bought two new Motorcraft batteries installed , NO CHANGE, so is it natural safety, key switch, electrical ignition switch, solenoid on starter, is there a solenoid between key and starter?

My brothers high mileage 7.3 ran out of gas because of a broken fuel pick up line. I brought him 10gal fuel, primed out of it and now the truck is sputtering and sounds like it's running on 2 cylinders. It's not just air in injectors or something it sounds like crap. It's getting fuel at least to the bowl.
