Ford 7.3L Power Stroke (1999-2003) :: Shut Off Suddenly Going Down The Road
Ok after rebuilding trans and being down a couple of weeks, I went on my 1st run since completing. Noticed when I started truck this morning it didn't turn over as fast as it was. 30 miles down the road Airbag Light comes on, and then volt meter dropped to 8 volts. Got stopped with truck still idling checked everything I had the tools to do so for. Decided to get back to my shop where I had tools, and 5 more miles and 55 mph truck just shuts off. Lost all power, truck would only click. Put my booster box on battery and gauges went back to normal but still wouldn't turn over but maybe once? Only place within a mile of my location was Walmart. Bought 2 new group 65 batteries, installed them and Shazam cranked right up no more problems. Short of the story bad batteries that checked Good with a load tester don't mean squat!

Lately I had a couple glitches seemingly unrelated with this electrical system. Something just failed. I have two new motor craft batteries cleaned all wires/ clamps. The alternator has been tested good. The other morning I started my truck and smelt a wire burning up before I took off. Battery positive to glow plug relay was hot. The solenoid was junk so I replaced it. Still not the problem. With the battery positive hooked to the solenoid, truck will not shut off. It will shut off by key if the wire is unhooked. I do know this. When hooked up, the battery positive is feeding voltage (.4v) through a new solenoid to the PCM, thus keeping the pcm life when the key goes off. Bad pcm? With the battery positive hooked up to the glow plug solenoid. There is such a large draw that the charging system cannot keep up. Wich out me on The side of the interstate at 1 am as I watched my lights grow dimmer til truck stalled. U hooked the battery positive from solenoid got a jump and been fine since....however, there's a major problem lying there right?

Comming back from hunting today my truck suddenly lost power and stepping on the accelearator had no effect at all. We were on the highway thru the mountains but on a fairly level stretch for a few miles. Managed to pull the truck and toy hauler over and the engine was running fine but stepping on the accelerator had no effect. The check engine light came on every time I stepped on the throttle and went out when I released it. It started fine but no throttle response. Switched around a bunch of relays and checked the fuses and still nothing.
Not liking my parking spot i tried to see if it would move down the road at an idle but it would not. Then I thought to try it in 4 wheel low and as the shoulders were soft it wouldn't move forward so tried reverse and went back a foot, forward again and moved a foot and a half. did this several times and all of a sudden the throttle responded, took it out of 4 wheel and it ran fine all the way home. What would have caused this? I was ready to call a tow truck which would have been several hundred dollar bills for where we were and with the trailer
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Suddenly Shuts Down While Driving
This started about 6 weeks ago. While sitting at a stop light the motor cut out. After some research I replaced the cps. Truck ran fine for about 3 weeks, then shut down again while pulling into the driveway of a store. Replaced the cps again (this time with a ford one). Ran fine for another 3 weeks, then shut down again on the freeway. No CEL on any occasion.
It's just like someone turned the key off. No rough idling at all. No smoke during starting or driving. When it shuts down, it will not start again for 20-30 minutes, no matter how many time you crank it. It will just turn over, no sputter. When it fires up again there is no air in the lines either, it runs like nothing happened.
I'm now thinking it might be a ipr issue...is there a way I can check myself or does it need to go to the mechanic? Or is it something completely different? This is my mother in laws daily driver, 178k. She does not drive on the freeway, 80% of the mileage is city driving. What could be going on?

I have a 2002 ford excursion. I know they have cali emissions. It runs fine then suddenly dies while driving. We've replaced the glow plug switch and relay. Neither one fixed the problem. we washed the motor a while back and it fried the programmer wiring.

My truck is an 02 F250 7.3 with 280,000+ miles on it, so I wouldn't be surprised if I might have a number of things going wrong. It runs pretty good, but is still far from 100%, at least up to my standards. So the problem has been going on for the last two or three weeks and got worse today, and there were a few things leading up to it as well. I'll start off with the first thing that happened that I think might be related. It was about 6 months ago, my buddy and I were putting my new headlights in.
It was parked in his garage and we backed it out a little bit to try and adjust them. It was sitting there idling for a minute or two and just shut off or almost stalled out. Tried to restart it and it wouldn't start, tried multiple times to no avail. It acted similar to when I had glow plug troubles when I first got the truck, it would just crank and crank, but never actually kick over and start, along with putting white smoke out the exhaust. Ended up waiting about a half hour and then the truck fired right up with no problems after that, so I didn't think much of it.
Then fast forward to last week to when something similar happened. Started it up after sitting for a few days, started right up, idled for a few seconds and then just shut off. Started it back up ran for a second and died again. Tried a third time with the same result. Fourth time fired right up again and stayed running, let it run for a few minutes and was fine. Also along with this, there was a bad squeaking coming from the front of the truck, like what a belt would sound like. I have recently replaced the belt because it was squeaking and actually got chewed up and almost shredded completely apart.
So not sure why it is squeaking again, but not sure if this could be related or not. Then took it back to my dorm room to get my stuff, and then made it the hour or so drive home from school, without issue. Even went to a few stores before I went home, and shut the truck off and started it back up multiple times, again with no issues. When I drove back earlier this week it was fine until I got there and put it in park. It idled for few seconds and then cut out for a second, but then idled back up and continued to run fine. It has done that a few times as well. So it will do it on a cold start or after already fully warmed up.
Then it got worse today. Again had trouble starting it cold, same as what I explained early. Except second time cranking it wouldn't start at all, then on the third crank it started up and stayed running. But on the drive home is when it got worse. About 5 or 10 minutes into my drive, was just cruising doing at about 45 or 50, and truck just shut off, died/stalled out. It cut out and shut off for a second or two and then started itself back up and continued on like nothing happened. It scared the crap out of me the first time it happened, I was waiting for something like that to happen, but still wasn't quite ready for it.
The truck acted just like it would before you start it, with the key on, dash lights worked and the radio still worked. It did this 4 more times in similar ways, would die and then start back up, at various speeds and at roughly 5 or so minute intervals. I decided to just keep going as long as the truck would start and stay running, hoping to make it home. It did it a fifth time and this time the truck completely shut off and wouldn't restart itself. It was hard to see, as I was watching a few different things at one time, but I think it tried to restart, I noticed the tach bounce between 200-400 RPMS and then die. So I had to pull over and then restart it, fired up and drove fine. That was about half way home, and I made it the rest of the way home without any more problems.
So obviously I'm wondering what would be causing the truck to do this? I've done some reading and have a couple ideas, but not really for sure on anything. I was thinking maybe the CPS, I think it can cause a no start issue. Could ICP or the ICP sensor have something to do with it? I was also thinking maybe something fuel related, such as fuel pressure or a bad fuel pump. Any of those sound to be on the right track?
I have the torque pro app, but not exactly sure how to use it yet, and also just got access to my Uncle's Snap-on scanner, so I ran some tests and pulled some codes. How to more utilize these tools in diagnostics. I did get a few codes, but I'm not exactly sure how they might be related. The codes are pulled are:
P0470 Exhaust Pressure Sensor Circuit Fault. Just cleaned that out as well as the tube about a year ago, but I guess could be clogged again or has gone bad.
P1274 Cylinder 4 (E) High to Low Side Open. Did some reading and figured out that this could be UVCH related. At the same time, about a year ago, did new injector O-rings as well as all new Motorcraft UVCH's, so can't imagine that one is bad. Or that one could be loose, I would have guessed it would have happened more when I first did them, not a year later, but who knows.
Also pulled P1876 T-Case 2wd Solenoid Circuit Fault. Not sure if this is related at all, but also not sure what it means either. I read that it could be ESOF system related, which I do have, but I have manual lockout hubs, so maybe that's why it throws the code.
Also a few things that may or may not be related, but I think worth noting. Ever since I've had the truck the check engine light will pop on and off sometimes. It will do it on a cold start or, when I first start driving and its not fully warmed up yet. It does it most when the engine is still cold, and it almost never comes on once the truck is fully warmed up, but has came on and off more frequently lately. When driving, it will only stay on for a few seconds and more often when I'm lugging the engine or at lower rpms, and will commonly shut off if I let off the throttle.
I don't think it really comes on at higher rpms. I also have a slight oil leak in the valley of the engine, seems to maybe be coming from the front of the motor. Nothing too serious, leaves a small puddle where I park, loses enough to be at the add mark, a little before an oil change. Changed the oil about 1500 miles ago and have been able to notice a slight drop in oil level. Also I have changed the fuel filter in the last 500 miles.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Hot No Start / Shut Down
My truck occasionally gets a hot no start issue and it's been happening more frequently. Mostly it happens if I drive it up to operating temp turn it off for a short time, then try to start up again. Usually, if I wait 15min to an hour it will start up. It has died on me while driving too, then I have to wait and periodically try it. I've noticed in this situation that if my glow plugs turn on for only a short time, it won't start. But once the motor has cooled enough that the glow plugs stay on for the longer duration, then it will start right up.
I've replaced the CPS, rebuilt the IPR, did the ICP unplug test, rebuilt the injectors, replaced the fuel filter.
HPOP oil level is good, changed the oil maybe 500mi ago. When it's a no start, the low oil pressure gauge does start to read after some cranking, also the tach does read. It throws no DTCs. My reader isn't able to monitor live sensor data.
There is some oil in the valley, but I can't find the source. I think it's probably the turbo pedestal. What else should I check?
Ford 7.3L Power Stroke (1999-2003) :: While Driving F250 Start Chugging / Lose Power And Shut Off
I have a 99 F 250 7.3. It runs fine at idle even for a long time. When I drive around the block a couple of times it will start chugging and lose power and shut off. I have been mixing fryer oil with the diesel. I changed the fuel filter, oil change, crank sensor and fuel pump. I added 15 gallons of diesel and diesel treatment. Pulled fuel filter and bowel is full I'm not sure where to look next.

I have a 2000 F350 with a 7.3 I have just set a brand new motor in this truck with everything in it new including the transmission injectors are 175/146 from Thoroughbred Diesel. The engine is Bored 40 over studded heads return regulator system as well as a pre pump filter and a javelin and Hutch mod on the tank. When we went to start this new motor the motor turned over and sounded like it was going to fire off pretty quick but instead I'm just getting white smoke and lots of it.
I failed to mention that the injectors are single shot vs. Split shot and then I did have the programmer Tuned to these injectors through thoroughbred there is no fuel in the oil no water in the oil no oil in the water everything seems to be good all the pressures seem to be good and at this point I am lost no one that I have found in the area, where to begin. Seems to me that this is a loading up issue and it seems to me that the only thing that could be causing this would be programming but I don't know.
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Won't Start When Motor Cold?
I have. 2001 excursion with a 7.3l deisel. 167100 miles
It runs great but if it sets over night when the motor is cold it will not start.
You have to plug the block heater in for about an hour or more for it to start.
To me it seems like glow plugs are not working? It had new glow plugs out in from the po.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 Shut Off And Would Not Start Again
I have a 2000 f250 7.3 with about 230,000 miles on it. So I filled my truck up to go out of town got on my way drove about 50 miles and the next stop I made the truck shut off and would not start again. I figured CPS went out again! nope changed it still not start. So check the fuel pump seemed fine was getting diesel. Checked oil, was a little low so i topped it off nothing. So i left the truck over night and came back on sunday still nothing. I finally got it started with a shot of quick start i know its not good but i had to get this Truck home. I drove and made it almost home took my foot off the pedal and it stalled again so i pulled it home. Had a guy go over and scan it and it says the oil pressure is at 30 psi when cranking so he says the hpop is probably bad.

I have a 02 f250 4x4 7.3l.... I drove it all weekend and no problems. It sat till yesterday I got in it to go to church. It started up and had a little miss was around 60 f. Then the od light started flashing. Not in any code just constant flash. I was parked down in my drive way. It idled fine but acted like it wouldn't take fuel. So looked around and found the hose on the map sensor was broke.
So today I fixed the hose. Checked the oil level and battery connections. Still running weird and flashing od light. I got under the hood and wiggled plugs I unplugged the ice. It revved up then back down and started running smoothly. Got in it and it backed out of the drive way. It ran and drove fine. What I need to know is why??? The ice is a new one from Ford.
Ford 7.3L Power Stroke (1999-2003) :: 2001 Excursion Shut Off / No Start While Driving
I am a new and very happy 7.3 owner. i have lurking around these forums and decided I didn't want to be a creeper anymore. So onto the fun stuff.
Yesterday my wife was exiting a freeway and the Ex shut off while exiting. once she came to a complete stop she tried turning it on and it would start then immediately shut off. she was able to turn it on and it would run then shut off as she drove across the intersection. once she made it across a good samaritan offered to park it for her. She noticed a little bit of black smoke but she told me that the guy was revving it to keep it running.
Luckily there was family at the mall and she waited for the flat bed to arrive. it sat for about 2 hours and they tried starting it and it would start then die. no more black smoke though. we had it towed to a diesel repair shop and they went to start it today and alas it started right up. they let it idle for 30 minutes and it was good. they test drove it and all good. they ran the codes and got the following:
P1876
B1352
B1483
U1147
One thing I did notice a couple of weeks ago, while driving on the freeway cruising about 65, the Ex surged a little and then ran fine. then another time it surged a little while idling. Some more info on the rig. it has a banks six gun tuner and has a cold air intake and exhaust. And it has a Banks Big Head wastegate. I bought the rig 2 months ago and changed all the filters and fluids.
Ford 7.3L Power Stroke (1999-2003) :: 2000 F350 Would Not Start / Motor Fire For A Split Second
The night temperture was only about 37 degrees. But every morning my 2000 F-350 7.3 crew cab 188,000 on it would not start. The first try there would be a split second where the motor would fire, but that would be it. I had to plug the engine block heater into my generator for at least an hour before it would start. I don't see how all the glow plugs could be bad at once??

I've developed a problem, usually when starting, that the truck will crank over, start and idle for a few seconds and then shut off. The few seconds it idles it doesn't get any throttle input. I'll crank it back over taking a little more than usual to get it started. When it does start it seems slightly sluggish but that quickly, like almost immediately goes away and the throttle is working again.
Oh, 2001, 7.3 stock w/200k
Ford 7.3L Power Stroke (1999-2003) :: CPS Replaced / Started Once Now No WTS Light Again / Won't Start
I was driving the truck a couple of weeks ago and it just died. I costed to the side of the road. It cranked but would not start. noticed the WTS light was not on. I bought a new one from dealership and installed it and it started right up. I assumed I fixed it. I let it warm up and drove it around the block and parked it and plugged the battery tender back up. the other day I got in and no WTS light again.
I was going to look at wire bundle over valve cover and 42 pin connector. Is there any other issues, I need to look at? Is it possible I just got a bad sensor? My guess would be something is shorting the sensor out if thats the problem so before I just put a new one in I thought I would ask the pro's. I have not done a lot of work to my truck aside from replacing the water pump, hoses and coolant.
Ford 7.3L Power Stroke (1999-2003) :: Start Rough When Cold - Injectors Not Working On 165k Motor?
Replaced o-rings, injector cups, glow plugs and UVCH with all motorcraft parts 2 years ago and the ICP, IPR and resealed the HPOP last year. I use rotella 15W-40 oil. It has been hard to start when it is cold and runs rough with little power until warm for a few seasons now when it is cold outside. There are no fault codes or issues otherwise with the mostly stock truck. A buzz test when the engine is cold only #6 sounds strong and #8 isn't quite as bad as the others but the others are hardly audible.
Cause:
1) Can 6 to 7 injectors really go bad in 165k miles? If it is injectors I believe the Alliant look to be the way to go with type ADs?
2) Since it is like flipping a switch and the number of injectors effected is it possibly the 0.1% of the time it is the IDM when there is a miss and no SES. From my searching and swampdiesel if there is a miss and no SES it is 99.9% it is not the IDM or harness since it actively checks continuity.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - Phone Charger Melted And Smoke Started Coming Through The Vents?
Truck is a 02' F350 xlt crew cab, 7.3l, 4x4, 4R100, manual transfer case, 125,000 miles.
So me and the family were pulling out of the driveway tonight and electrical smoke starts blowing out the vents. My wife had just plugged a cheap USB charger into the auxiliary outlet above the cup holders for only 30 seconds. I immediately pulled back into the driveway, yanked the charger out, and found it had melted a hole in the side of it. No smoke had come from the charger or the outlet. The outlet looked fine and wasn't hot to the touch. I pulled the dash off real fast and started grabbing wires, feeling for anything that was hot or melting. I couldn't find anything.
I pulled the cover off under the steering wheel and couldn't find anything. I never turned the truck off while I was looking. After a few minutes, I noticed that the cover over the fuse panel was warm. Pulled the cover off and felt every fuse end and they were all cool to the touch. The relays in the middle were all pretty warm(almost hot to where I couldn't touch them). I was still faintly smelling the burnt smell and I couldn't tell if it was just stuck in my nose. I disconnected the batteries and we had to switch cars(heading to a bbq).
So I just got home and I'm going to start looking for any obvious signs first. What could be going on at the panel? So far, everything is still working. I haven't found any blown fuses.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - Lopes At Start Up When Started Cold
I recently purchased a 2000 7.3, when it's started cold it's lopes at start up unless I give it some gas and then it's perfectly fine. If the truck is plugged into the engine block heater it starts normal. I changed the oil the day after I bought it and put 15w-40 in it and then the rough idle started. So I don't know if it was like this before or because of the thicker oil I put into in the cold. It also has a service engine soon light on and the code that comes up when read is to the icp sensor. When looking st the sensor the blue wire going to it looks cut and is disconnected. How would I reconnect these wires and see if that makes the check engine light go off.
