Ford 7.3L Power Stroke (1999-2003) :: Truck Stutters On Road After Long Drive When Running
Sep 11, 2015
This is wife typing in middle of trip. Today we drove almost 300 miles down the road before it stuttered. We lost the tach but nothing else. No check engine lights. It has done it a few times since. Watching with Torque and don't see anything there. Have 100 miles to go and it's happening more frequently. Replaced CPS 4 weeks ago with a Ford grey. Running down road it's 95 day. Oil was checked to be good at 211, transmission 182, EGT 790, pulling enclosed 6x12 cargo trailer. What can I check?

Background on the vehicle, Last week installed Swamps 200cc/30% injectors with a 38r. Had swamps reburn my chip for the new upgrades.
But heres the problem i noticed starting the truck was a little harder ( longer cranking ) till it would start never thought of anything since i read air gets in and can cause it but then yesterday and today its taken 30 minutes to start the truck since i have to do a trial and error.
The truck just seems like the batteries are being drained or something along those lines. i also noticed my gauges keep resetting back to blue( default color). Today I plugged a battery charger up all good voltage i charged them so both read 14v and still no start. So a couple of attempts at starting with chip in and ICP on nothing
I unhook the chip and ICP get a half start then eventually it starts. After then i can hook it all back up and it starts good for the rest of the day but for what ever reason after it sits all night it doesn't want to start up right away. I'd like to figure it out today since id rather not wake up at 4am and attempt to do this all before work each day.
I noticed that my gauges would reset to the default color after each turn off. So i unscrewed my ECU and then redid that to make sure its tight. along with making sure the chip is seated properly. after that it stopped resting my gauges. Whether that's the issue or not i cant say but ive been checking my HPOP oil level since i stopped driving it around 1400. and hasn't changed oil levels are good. I plan on starting it before I go to bed around 2200-2300 just to check and see what happens.

On the way to work, the truck seemed to have a miss at idle and the CE light came on. Long crank to start leaving work, and truck starts losing power and eventually died. No smoke while it was losing power. Towed it home and checked the fuel pump and lines for blockage and found nothing.
2003 7.3 F-250 430K miles
strong cranking but no start no smoke out exhaust
Oil changed recently
IPR changed
Both UVCH gaskets and pigtails have been repaired.
ICP sensor and harness changed, also disconnected no change in cranking.
fuel filter changed today (no oil in bowl)
3/4 tank of fuel
dash gauge for lpop goes up to normal range during cranking and oil light turns off.
WTS light comes on and turns off as normal
tach gauge moves up between 100-200 during cranking
fuel pump turns on and pressurizes system like normal and turns off.
Ordered AE for the truck, and it directed me to the passenger side bank high open. Fixed the harness on that side and still nothing.
Sent off the IDM and it passed with flying colors
So now i'm leaning towards the HPOP, but would hate to fork over the cash for it and still not get anywhere. I'm going to take the valve covers back off and check the discharge ports for the injectors tomorrow.

On Saturday I drove my truck 450 miles, all of it towing, in hilly New England. The turbo boost gauge was operating at 20psi or higher for many of the hills, and the 13mpg average was indicative of how hard the truck was working (normally empty I will get 20+). The next day, I drove it about 3 miles and it started a regen. Why? Wouldn't it have been passively regenerating for most of those miles? A steady 75mph for hours at a time?

I recently (in the last few months) have noticed my truck (1999 F350 duallie) seeming to be running very rich … I pull a 32' trailer with it and noticed on the art few trips the front and right side of the trailer covered with diesel fuel spots when I got home …. It also smells very rich when idling…. The last couple times I started it in the mornings it seems to crank a very long time before it starts …it still runs but its got issues evidently … it has these 3 codes :
P1280
P0475
P1670
The 1670 will clear , but the other 2 I can't clear, they are right back every time you turn the key on …

I have a 2000 Excursion diesel 7.3. I drove it for an hour yesterday and it drove great. When I arrived home I left the truck running and put it in park. Checked the mailbox and jumped back in the truck and put it in drive and it would not move. Tried FWD and reverse. Moved a little in reverse.
I turned the truck off then cranked it back up put it in drive and it drove fine..... Took it for a test drive and seems fine.
Did the same thing today. Went to drop my kids off and I put it in park and left the engine running. Put it back into drive and it would not move.
Turned the vehicle off and back on. Put it in drive and it drove off fine.
Fluid is full, red and no burnt smell. Wondering if this is converter or electrical and how long I can drive it like this.

I bought a 99 7.3 been in the trees for a few years pulled it home and now trying to get it running. Did a service new filters and oil fuel too. I can get it to start and will run but runs very rough and if you put it in drive cant pull its own self. I don't have a check eng light on. And found out my scanner is a pos lol. it will hooked up and then try to pull codes and loses it connection. But that's the scanner will not work on my other 7.3 as well.
I am making high pressure oil checked off the rail with gauge and it will build up to 2000 psi when I rev it. but missing like crazy. I swaped the pcm and idm out of my running 7.3 and it didn't change a thing. I have checked the pass though and they are fine. pulled drivers side valve cover off and no oil leaks when running and rockers are fine. new ipr valve as well too. I know I need to get a scanner to talk to this thing better.

Traveling right now. Limited access to FTE.
On the way to the airport this morning at 4:30 am, the engine simply did while running down the interstate. Absolutely no symptoms leading up to it. Turns over fast but will not start. White smoke from tall pipe while trying to start.
I unplugged the fuel bowl heater and checked the IPR tin nut and the ICP sensor connections... Nothing obvious.
Problem was CPS and the engine is now running fine again.

I have a 2002 f350 7.3. It was running fine 2 days ago. After I put some diesel in it my water in fuel light came on. I drained the water out and took all the fuel out and put fresh diesel in it. It starts up fine and idles okay but when I try to drive it it looses all power and acts like it's starving for fuel and almost dies. It was smoking white smoke for a little bit even after I took all the water out but now it's black. What it could be.

2003 CC 4x4 ... I am pretty sure I know what is going on, but I wanted to start a thread for when I confirm it. I am driving to work this AM and I hear the door ajar chime and I think to myself, uh oh...gauges all look good, there are no lights illuminated on the dash. I get to work and turn the truck off and my fan stays on. I think the ignition module is going bad. Either that, or my remote start is going on the fritz. I will update when I find out more.

I had an HPOP line burst and soak the engine compartment with oil. I replaced the line and degreased the engine and rinsed it off. I started the truck and let it idle for 15 minutes or so before driving it. On the way home right after a shift it started chugging and running terribly. The check engine light was on as well. I limped it the mile or so home and shut it off. I restarted it and it runs just fine. I checked the DTC's with Forscan and there were a bunch of things that were mostly related to the HPOP and the MAT sensor that was shredded when the line blew. I left the hood open to dry out today and I'm hoping it is just some water in a connector. Does that sound plausible?

My spine was damaged in an IED blast in Iraq a few years ago and my truck is getting harder and harder to drive. It sends every little bump up me. It looks like I have the original shocks on there.
What is recommended for shocks or possibly seat upgrades or any other possible solutions. I love my truck and don't want have to get something else.
The most I haul is my jeep on a trailer and occasionally two jeeps (8000lbs)...

I have changed pickup filter in tank and cleaned 2 tube filters in tank i thought that would fix it.

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.

Just happened today right after I bought diesel. thought it may be water in fuel but after researching wondering if it is injector, etc. It starts every time knocks real bad sometimes for a minute, but clears up to idle ok. During idle no smoke, slightest acceleration however produces white smoke harder I accelerate more it plumes and it smells like diesel in the air.
Cannot get past 15 or so mph till switching into 2nd gear then 25mph max. Had to drive 4 miles like this I can say it cleared up and drove 1/2 mile until I had to stop at a traffic light then going from idle to acceleration again ran bad rest of way home another 2 miles.
A few years ago I did have a rough idle and accel. similar and it ended up being the broke pick-up/sending unit in tank (but of course that was when you get to around 1/4 tank of fuel and didn't run bad above that much fuel in tank), plus there was almost or more than a gallon of water in tank. I have done the mod for the fuel pickup with hoses, filter canister, etc. but wondered at first today if I had gotten bad gas or water in the tank again. Not sure how that much water got in the tank to begin with but that was bout 5 or 6 years ago.
Truck has over 200k miles and Ive had it for 11 years. In the morning will check the ICP sensor by unplugging look at fuel filter bowl, etc. A question I have is: Is water heavier than diesel, would it run thru my line first? thinking diesel is heavier than gas because of oil content....

Battery light comes on when the truck is running at less than about 1200rpm, but I see zero movement on the needle. Weird thing is i charged the batteries and tested the alternator with my multimeter and it was reading 14.1-14.2 which is nominal. Run it for about 10 min then it reads 12.3-12.8
I'm thinking a bad cell in the battery or alternator is going out. Oh and all the connections are tight, wires look good. 2001 f250 4wd 7.3 intake exhaust basic tuner gauges. Could the constant heat be a factor?

I just bought a 99 f150 it has 257000 miles on the truck, and a motor and transfer case from an '01 with 215000 miles. I'm not sure about the maintenance on the truck but when I'm on the highway the truck randomly stutters. I was thinking it was coming from the tranny because the tranny was overfilled by almost a quart but really not sure.

I have a 2003 Ex 6.0 psd, 155k miles, and was on my way to work to a site 40 miles from nowhere. I was about 10 miles from my destination cruising around 65 when the Ex started losing power. I would say within a couple of miles power was gone and i had no choice but to pull over. I popped the hood, got out had a look around and saw no leaks or anything out of the ordinary. Let it sit for a few minutes and tried to restart it to no avail. There was no check eng light or any signs something was wrong.
I just so happened to have my OBD scanner with me and plugged it in and read for any extra codes. Three popped up on the screen: P0232, P0263, and P0278.
P0232 Fuel Pump Secondary (Feedback) Circuit High Voltage,
P0263 is described as a cylinder number 1 contribution/balance. In essence, this code is stating that the number one cylinder in the firing order is experiencing a fuel-related problem.
P0278 same as above for cyl 6.
Right away i thought the fuel/lift pump took a dump on me and was causing the fuel issues in the two cylinders.

I have an 03 with a 6.0 diesel, going down the road and started losing power and then died. Won't start, and I don't have a scan gauge. Several sources said ipr valve, and from videos on youtube I thought may be a good place to start. I bought a socket and pulled the valve, to check the screen. There is no screen whatsoever on the ipr. The oils clean, as I had changed it about 200 miles ago, and I ran a magnet in the hole looking for a screen, couldn't find anything so I used my fluid pump in the hole. No trash, screen or anything. Do some ipr valves not have screens? What would be my next step??

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 early 99 f250 super duty 7.3l and it's giving me fits. about a month ago the truck started to do a hot no start. drove truck for about a hour. Shut it off and half hour later no start. Let it sit over night and would start with long crank.
Changed CPS no change. Pulled tuner and set back to stock. No change.
Changed fuel filter, no change.
After reading forums changed IPR and truck started and ran great. About a week ago back to the same problem. Battery's are about 2 months old. Oil change and oil filter a month ago.
Checked the hpop reservoir and its 1/2 from the top.
Checked fuel bowl and it has fuel. no sign of oil in it.
Drained bowl and watch bowl fill back up. seems to fill quickly.
Pulled passside valve cover to check for bad orings while cranking.
Every thing seems fine. have not done driver side yet. used FORSCAN and ran buzzed test on injectors and they all buzzed what seems to be about the same. ran test couple of times to make sure. this morning I ran a live scan while cranking and this is what I got right before it started. ICP 660.6psi, IPR 64.84% and RPMs 227. took 8.86 seconds to start. after work scaned again for hot no start and this what I got. ICP 292.9psi, IPR 55.86%. and RPMS 203. unplug ICP and no change. still will not start. one thing I did notice when plugging ICP back in I looked down in side at the pins and can see what seems to be bubbling around one of the pins. the pig tail has just the slights sign of oil.
