Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss And Almost Shut Down At Random Times
Oct 16, 2015
I have a 2001 F350 7.3 the truck will at random times loose power and almost shut down. A while back I had an issue with the uvch plugs and changed that out. Truck ran fine till I got some dirty fuel from a diesel tank at my friends farm. I did the hutch mod cleaned the tank and now have a frame mounted screw on filter before the pump. I cleaned the fuel bowl and changed the filter. Fuel pressure stays at 59psi and drops to 56psi wot. The truck is tuned with an edge programmer. After these mods the truck ran awesome for over 2000 miles. Now it has the above stated problem. I have fuel and hpop guages along with egt and boost. During the problem egts will increase rapidly and it seems like it is starving for fuel.
Hpop gauge reads 3300psi or above during wot and shows good pressure during these mishaps. I have auto Enginuity and I get a different reading at wot of only 2600 psi. The hpop gauge is tapped into the icp sensor per instructions and has been installed this way for a while with no issues. The tune has been on the truck for over 40000 miles. The only thing that I can come up with is it will occasionally throw a p1211 under wot or pulling my Gooseneck Dump Trailer when loaded. However it acts up sometimes and doesn't throw the code. Sometimes you can shut it off and start it back up and it's fine other times it will last for the whole day. My only guess is low pressure from the hpop but I don't reflect this from my gauge only on AE at wot. Wouldn't a bad pump act up all the time? Am I correct to think it is just the ipr?

I drive a new to me 2005 F350, he has a 2001 F350. While we were talking he said he didn't think his pickup had the power it should have. He pulls a 5th wheel camper that weighs around 8000 pounds fully loaded. He said it takes a couple of miles to get to 55 mph, and it is hard to hold the speed. It doesn't have the power it did when he first got it last year. He was told that a diesel is slow getting started. He rode with me in mine, when I dropped it about half throttle to pass a slow car he said he could tell mine had way more power.
His check engine light is not on, it starts good both when hot and when cold. It runs smooth, no miss as far as I can tell listening to it. What are some common issues that could cause this? He did just change the oil and fuel filters, not sure about the air filter. He said the power loss came before he serviced the engine, and did not improve after the fuel filter change. Where to start? He was also told to check the filter inside of his fuel tank, so he is getting ready to drop his tank.

Dad has a 01 one ton with the 7.3 and isn't real tech savvy so I'm posting for him. He is the original owner and has been complaining recently about the lack of power. Particularly the upper end. He is having to downshift way more often and where he used to not have to. And we've both noticed a very noticeable shake at idle. Not a vibration but a true shake. He changes the oil every 5000 on the dot and I've gone and changed the air and fuel filter and ran hose and see foam and royal purple injector cleaner through it with no results. Truck is all stock with 225000 on it.

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

I just bought a 2001 F350 diesel with 120k miles on it a couple weeks ago. Friday I headed out to Oregon with my 16 foot enclosed trailer filled with jet skis (about 4-5k pounds) for a competition. A few minutes after being on the freeway I noticed the truck did not have good power. About 30 min later while climbing a steep grade the truck almost went dead.
I started at 60mph and by the time I got to the top i was at 15mph with the throttle pinned. the motor sounded funny and shook the truck more then normal. After wards on the down side of the grade the truck started to act normal. I took it to my buddies house and switched trucks because I didn't trust if for the 13 hour drive.
Today I talked to a mechanic at the dealership and he said that it sounded like injector o-rings to him. I went home, pulled the valve covers and started the motor to see if anything is leaking. steam was coming from the valve area and the down spouts on the injectors was flowing oil. The thing that looked especially abnormal was one of the injectors looked like fuel was dribbling from it. I don't know if that is a problem or not. I couldn't tell if it was fuel or oil but no other injectors had fluid coming out near the wire connections.

I have a 2001 F350 XLT with cloth seats. In 2003 I upgraded those seats to power seats.
- When I upgraded to power seats I did not run a new power wire. Since my 2001 was at least fused for power and heated seats I located the Power seat 30amp power wire.
- That wire is located on engine compartment fuse #15 (Circuit 5298 as I recall) and Dark Green. It comes through the firewall and runs down the drivers side kick panel along the floor and then intersects with the power and ground seat belt wires that ran under the seat.
- The ground wire was coiled and attached to a ground stud behind the drivers side kick panel.
About a month ago I had a mouse get in and chew my seat wiring to shreds. I built my own harness and am good to go there, however since I had these seats all apart I decided to replace the foam and add HEAT.
So that brings me to the specific question. In the engine compartment fuse box, there is a 30amp positive wire for Heated seats. My schematic says it is a 14 gauge wire RD/BK on circuit 1153.
Where in the heck is this wire? I have literally tore the dash apart looking for this wire.
- I have verified the following with my fluke continuity tester.
- It is not part of the four customer access wires that drop on the right side of the interior fuse panel.
- It is not part of the tow wire bundle.
- I have checked the bundle that the Dark Green Power seat wire is in and there are no RD/BK wires in that bundle. I also poked the other 2 14 gauge (Yellow/Blue) wires in that bundle and verified they are not them.
-I have checked the three wire bundles behind the passenger side glove box and was unable to locate.
- I have verified it is not stored behind the compartment below the cigarette lighter.
I am looking for info which wire I am talking about and knows where Ford stored them when not used by having the XLT Trim with cloth seats. Yes I am aware that I can run an additional wire with a 30 amp fuse to the batter, but I would prefer to use the system and fuse that was designed for this.

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

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?

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.

Have no OD, when you press the OD button nothing happens and then the OD light flashes until she's shut down. On start up no flashing until OD button pressed. All other gears shift lovely. Haven't checked codes yet.

I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

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

My one owner 2001 7.3l F350 w/ 265K miles died a few days ago at a traffic light. First time it has ever died on me other than a CPS. This dying was an almost instantaneous with no CEL light, unlike the CPS's hiccuping and dash light up. I put it in park and it started right back up like normal. I continued about my errands and made it home. I have since driven it two more times the same distance and it has not died.
What I have done on this truck the past year.
-Replaced ICP -3/14
-Rebuilt IPR and checked IPR plug -6/14
-Replaced fuel filter every 7500 miles and I am probably due another one of those now
-Replaced air filter - 4/15
-Cleaned out both the sensor and the exhaust back pressure tube
-replaced CPS w/ dark blue unit from RiffRaff in -8/14
-checked main harness over driver valve cover and placed a piece of heavy duty wire cover wrap where they touch the valve cover -8/14
UVWH replace in 2008
Have a new IPR and pigtail coming just because I wanted to eliminate a bad solenoid on it. I also have a Torque Pro w/ blue tooth adapter on an LG tablet that I have yet to set up....but am working on it Will the truck throw any codes if the CEL didn't light up?

I change my motor in my 01 f350 ccsb to a forged rod one from a 97. When I put the thing in my inexperience cause me to screw up my torque converter in turn ruining my transmission. So after a rebuild I put it back in and she fit like a glove. Ever since I put the engine in i get a vibration at idle.
After I realize I screwed up the torque converter I figured that was the cause of the vibration. But now I know the trans is in properly I still have this vibration I'm thinking it's the position of the motor. I installed new motor mounts when I put the motor in but they were quite a bit off from the original points on the cross member.
My only idea to rectify this was to reinstall the original ones and try to position the motor back where it was prior to the engine swap. Or should I be looking elsewhere?

I've replaced the alternator and starter recently and both batteries and the truck ran fine befor that. But it sat for roughly 2 months and now it seems as if its not getting fuel. Will start with a shot of ether but will die as soon at it burns it off

I have a 2001 F350 4x4. My transmission went out a while back. It would only go in reverse. I had it rebuilt and it is still having issues. When I take off with speed from a dead stop it shifts late...about 3000 RPMs. It shifts fine until it shifts into overdrive. It will go into to 4th then right into overdrive causing the truck to act sluggish.
I'm looking into my truck not starting well at any temp too! I didn't know if it could all be connected some how. My mechanic said that when he first started my truck it had a MAP sensor code. He also said that when he unplugged that sensor it didn't change the way the truck ran..Still like crap. I have changed all glow plugs relays and even did the mod to it.

I have been having problems with my truck for about 6 months now. It start in Sept when my fuel pump went. I got a new pump and went to change it just to have the back clip break off. I fixed the line after getting 2nd degree burns from the boiling water I had to use to expand the line and installed the new fuel pump. Didn't fix anything.
At this point is was dropping below freezing every night ( I live in Canada in the mountains) so I thought it might be my plug relay again... changed that. After that my started has always missed so I figured I would change it out and sure enough the power bolt on the starter was broken. Changed it.
Then it started smoking and I read up on the quarter trick so I figured why not try that. I checked everything and they all checked fine but I am a glutton for punishment and figured I would do that valve cover gasket. So opened it up to find one of my glow plug wires on my harness was burnt up. I have a spare truck for parts so I grabbed the wire and replaced it. Still no change.
Today it was spitting out the usually raw diesel that I have gotten use to but when I was opening the gate to get a manlift for work I smelt oil just to find my turbo coved and the V had a small pool of oil happening there. I added 4L of oil and tightened up my valve cover back bolt on the passenger side... it may have fixed the leak but didn't have time to check.
I backed up to the manlift and it lagged a bit so I gave it a pump of the peddle and it died. Now it won't start. Charged batteries and tried after it cooled down but still no go.
In short my truck has been smoking for about 4 months now. It shutters at low RPM and stalls at the bottom of hills if I gear down on the hill (we have really steep hills around here). I have changed my oil three times in the last 6 months but it keeps coming out black (which it always has). No water in fuel or oil. Once and awhile it had problems starting when it was warm but after bellowing out massive amounts of smoke it would start. The truck turns over but wont start. There is no power where it died so I have to come home and charge the batteries every time they get low but even after it cooled down it still wouldn't start.
