Ford 7.3L Power Stroke (1999-2003) :: Engine Stalls After Warming Up For 10 To 20 Minutes
Feb 24, 2015
I have a 2002 F250 7.3 4WD automatic with 313,000 miles. A week ago it started stalling after it idled for 10 minutes. It acted like it wasn't getting fuel. It would sputter a few times then just quit. I changed the fuel filter and the truck ran fine the rest of the day. Since that day, it has acted the same way every morning at 1st startup. It idles fine for 10-20 minutes (depending on how cold it is outside), then hesitates a little, then stops. After going through 3 new fuel filters (thinking I had bad fuel), I stopped putting in a new filter every morning, and found that if I just waited 4 or 5 minutes, it would start and run fine after that. It then runs fine the rest of the day.
After it stalls, it will not start right away. I need to wait a few minutes. I've tried draining the fuel filter bowl also. No luck. I tried a new Cam Positioning Sensor. It seems to be related to temperature. It's been getting down to 30 degrees Fahrenheit the past few mornings. It starts fine and idles fine until the temp gauge just starts to move. Then, the stall happens. My fill-up just prior to this happening was with B20 Bio Diesel. I suspected that for a while. But, I've ran all that fuel through plus 4 or 5 regular diesel tanks through, so I no longer think it was related to that. It do see the check engine light when it stalls. I had a shop read my codes and the only code was bad KAM memory. The mechanic said that code shows up all the time on these engines and not to worry about it.

Having issues for a couple days now. Starting with the last two weeks while driving, the water in fuel, wait to start, and check engine lights would flash on. It would resume with more fuel as if nothing happened. Twice on separate days there was enough water that it shut it down in the middle of driving and it would have to be parked then restarted. One morning went out to start the truck, was inside for about 10 minutes and heard the truck shut off. Went out to see if it would restart and there was no wait to start light. Fuses have been checked and none are blown. Been shutting off like this for a couple days while trying to warm up, so it hasn't been driven because it hasn't ran long enough. Yes it's plugged in because of the cold.

I have noticed thru the cold months after I start my 2001 F250 7.3L 4X4 after it sits about a minute "warming up" that it goes into a high idle. The high idle will stop once I press the brakes. Is this normal?
I think this is a unrelated issue, but just started over the weekend. Was riding home, and pressed my brakes and the pedal moved almost to the floor. Not normal conditions for my truck. Usually the pedal is very stiff. I have noticed that my power steering pump has had a hum for months. I changed the fluid (ATF Mercon) within the last 6k miles and that calmed it down a bit.
After the pedal went to the floor, the hum seemed to quieten down even more. The power steering still works and the reservoir has adequate fluid and so does the brake fluid reservoir. I haven't noticed any leaks around the truck. I'm going to bleed the brake in an hour or so. The brakes pedal seems stiff when I press it after the high idle, but then it gets soft after a pump or two.

I hear a whoosh whoosh whoosh sound coming from the exhaust when its warming up in the morning. What is happening?

I have a 2001 F350 with the 7.3 standard trans. The previous owner put a toggle switch to control the EBPV as an engine brake, I've never used it. It blows white/blue smoke when cold but has for the last 4 years and doesn't seem any worse now.
Last fall I ran the truck the lowest on fuel that I ever have, the light was on for a long time and I thought I would run out. I made it to the gas station and filled it up then drove home. The next time I drove it I went about 25 miles and it started to buck while going up hill. This got worse and eventually the check engine light came on and it stalled.
It wouldn't start again so I had it towed home. I got it started a couple hours later but it would run really rough and only for a minute or so then stall. It will usually start again once or twice and stall, then it wont start again until it has sat for an hour or so.
I didn't have a code reader at the time so I started reading threads. Here's what I've done to date.
Changed the oil and filter, it was way over do. New fuel filter.
The oil level in the HPOP stays about an inch from the top, I've checked it a few times after its stalled.
Dropped the tank and cleaned the screens in the pick up, no change.
The ICP had oil on it so I replaced it and a new connector, no change.
Changed the CSP with a grey one, no change.
Changed the IPR valve with one from a buddy that was on an engine that was running. The truck ran rough for a min then settled down and ran smooth. I let it idle for 20-25 minutes with no problem so I thought the problem was solved. After sitting for a month or so I fired it up and its back to running rough then stalling.
I bought a Vgate ELM327 connector and downloaded FORScan on my laptop. (I'm still not sure what I'm doing). These are the stored codes P1281, P0475, P1316, P0478, P0470, P1211. I cleared all the codes. I did a buzz test cold and the Injectors all sounded the same.
I monitored the truck while running (rough) the IPR is staying around19.92%, ICP is 701.4psi. After 5 seconds the ICP starts to climb and so does the IPR, at 12 seconds the IPR is 37.11 and ICP is 1835.1 psi the it stalls. The fuel pw,ms is around 2.50-3.0 until before it stalls, then its 1.66. The only codes that come up are P0475, P0470, B1473.

On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.

I have a 2001 Ford Excursion Limited 7.3l with 199,980 miles on it.
It has a TS-6. My first problem is that when I come to a stop or slow down to a crawl then press the accelerator the engine stalls and dies. I have looked and looked at threads and can not find this example anywhere. There is no pressing the pedal and it remains at idle. It dies, shuts off, quiets. I have thought icp, tps, ivs
Second problem is that a/c is blowing hot. Other than being out of Freon, what could be other things to check. It does sometime go to default, but has done so in awhile. It does not blow cold in rear and hot in front. They both blow hot. I have replaced the pvh sensor.

Truck has a rough idle and finally just stalls out. I replace the under valve cover wiring harness and put in new glow plugs. With valve covers still off I started the truck in the issue still persist. I went ahead and unplugged each injector and each time the motor had a hick up .
What am I pulling apart and replacing next?

2001 Excursion 7.3 - stalls randomly, sometimes will not start. After the IPR was replaced it was rough for about 4 miles (I thought maybe air in the system), next 40 miles was flawless with 3 stops and restarts. Then it sat for a few hours and I went to leave again and the problem was off and on again for another 5 mile drive. Now it won't start in the driveway. It will start if I disconnect the ICP but the idle is still a little rough.
I replaced the normal culprits after a lot of searching on here:
CPS - replaced with autozone part, thought maybe it was bad new so went to ford and replaced with official part from the dealer
ICP - had oil in the plug and it would idle better removed so I replaced the plug and as much wire as I could - soldered, heat shrunk, good connections - both the pigtail and sensor came from Ford dealer
IPR - replaced with part from the Ford Dealer (FYI - 1 1/8" 1/2" drive craftsman deep socket from sears fit in the ratchet and on the part).
Grounds - found somewhere that the ground on the firewall for the windshield wipers can interfere with the CPS so I pulled it, clean the connections and made sure it was tight and secure.
No check engine light now - I received a few through the process, but did not clear them and there are no codes at this time (self cleared on the 40 mile drive)
I'm thinking it may be some electrical issue/short or a fuel issue at this point, bowl is full and the filter is fairly new (few thousand miles). I haven't done the Hutch mod, but have over 1/2 a tank.
I'm trying to get this going as quick as I can so I don't want to waste too much time, but I also don't want to miss a critical troubleshooting step to take.
Below are my thoughts on the next steps.
Research and test fuel pressure
Tow it somewhere to test each injector - I only have Torque pro to read codes and engine status
If fuel delivery checks out ok, start testing wire by wire on all of the above parts.

Lately when I am coming to a stop and roll up to a stoplight/sign in gear the rpms drop too much and it stalls. I let the clutch back out and it starts back, but will stall again if I coast in gear again.
If I just push in the clutch without the rpm's coming up like to change gears it doesn't stall, only when I downshift when stopping and then once I push in the clutch the rpms drop and don't recover.
Truck runs great otherwise, new motorcraft icp and cps doesn't work. Thinking maybe ipr, but idk. I can rev it in neutral and it doesn't stall only when it's under load coasting, it's like the injectors don't recover from being off while coasting in gear.

My f250 is having a stalling issue. It will run fine for about 5-10 minutes and then die out, already replaced CPS, fuel filter, and fuel pump. What else could be the problem?

I have had my excursion for almost 4 years, I love this truck. but lately we have been having issues that we haven't been able to figure out. First it has about 390K miles on it.
I ALWAYS have to plug it in. it could be 90 degrees out and I still have to plug it in. if it Is plugged in normally it will start fine. but then when I go to drive it, it wont have any power until I get like 2 miles down the road. you can push the pedal all the way down and it will go like 10mph. but once it warms up its fine. if I forget to plug it in, I will have to plug it in for about 2 hours and then it will start hard and run really rough for about 10 min. And it will blow greyish smoke out the exhaust.
But now I'm having the issue of keeping it running. it will start and run for 5-15 min and then quit and I have to wait anywhere from 10min - 1 hour to start it again.

1999 7.3l 6spd standard 4x4. Just bought the truck 4 months ago knowing it had a problem that once warm occasionally would t start. Happened a few times every week or two. But wait 15 minutes and the truck would fire back up. Then it started happening more often throughout a day. And I would have to wait longer for it to cool to start it up.
Icp has been changed
Cam sensor
Pulled valve covers to check to see if there were any injector o rings failing. They were all good. Put it all back together.
Pulled the IPR and tore it apart cleaned it all out
Started driving it ran great for a week. Then today sitting at a light the truck died just as if I had turned the key off. Wouldn't start for 3 hours. The. Fired up. Took it to buddies show and started checking things out again. Both batteries load test great and fully charged. Alternator pumping out 13.5 and up.
Codes i have pulled are waste gate to high /low
I forget the number for that one. The second was P1211. Cps has been changed and ipr cleaned. Think that I should replace the ipr of this happens again?
I did get w code a few weeks ago about low voltage at module. this code doesn't appear anymore. Since I checked the plug ins all looks good. But the PCM wasn't mounted properly. So I fixed that up and checked battery connections. They were very good so I re did all of that.
Anyway. Back to the problem. After ipr clean. Drove as she should until sitting at a light a week later. Truck just quit. Would t start back up until cold. Any thoughts. New IPR? Oil in hpop within half inch from top. And I don't seem to have any oil leaks. Did oil change fuel and air filter. Not low on any fluids. I had a 1997 too and threw a bunch of cash at it like this one trying to find the issues.

1999 F350. It has the 7.3 diesel engine. His complaint is the truck will stall out on him shortly after filling up. It makes no difference if he is driving at full speed or stopped at a light the truck has stalled in both situations. He reports that he resulted to only filling up to half a tank for a while and that seemed to stop the problem. I was thinking a vent problem. Maybe the gas cap is bad causing a vacuum situation But I have read a few articles about tank delamination and now I'm not sure what to think.

So I had a reman 7.3 and 4r100 dropped in my 03 excursion.. since then the engine fires up every single time.. ONLY when the truck sits for 2 days i have this issue where the truck fires right up, runs for 4 or 5 seconds then stalls out.. It starts back up on first try and idles rough 10 seconds then it runs great.. If it only sits 1 day i dont have the issue if it sits 1.5 days it will try to stall out and catches itself from stall out and doesn't stall about 3/4 of the time. The mechanic who is a reputable diesel mechanic cant figure it out.. they called swamps and they also were unsure.

So I went out this morning to start the truck up like I do every morning. It cranked once, and didn't start, which is somewhat normal. second crank it started right up, which is normal, then after about 2 minutes, it seemed like the rpms were bouncing and the engine got a little more slower and louder, then it dipped below 500, then stalled. After that moment nothing. It just cranks. Now it was VERY low on fuel, I've been this low on fuel and never had anything like this happen, so my neighbor took me up to the station and I bought 2 gallons. came back, still nada. I went out after letting it sit on the block heater for about an hour and noticed a small puddle of fuel under the truck on the passenger side. I went to start it and the fuel gauge went up to a half tank. cranked, no start. then again and it went up again but slowly started creeping back down.
Now the kicker, I have very limited knowledge of diesel engines, or gas for that matter. So if my intuition is right, this is probably going to be a learning experience for me... what should I check first guys? Its plugged in right now but I am sure that's not gonna fix it.. I am gonna change the oil first since it needs it, I bought shell rotella triple t 15w40 which im assuming is ok. last winter It was leaking fuel when it was really cold out but that was it, just leaking a bit and then after spring it went away. I know I should have fixed it when it started but I have an extreme anxiety to letting any mechanic near my vehicles and just about as much anxiety trying to fix it myself. I'm at a loss for what to do, I'm a pro with computers but this truck scares the crap out of me, I'm terrified I'll do something worse.
2002 Ford F250 Powerstroke 7.3 4x4, 218,000 Miles....

I have a 2000 4x4 Limited 7.3 Powerstroke. 290k miles and runs like a top. However, if I don't plug it in for a few hours before starting she sounds like an old John Deere Poppin' Johnny. I had the glow plugs replaced yet had to go back to the repair shop three times since because it threw a code each time. No codes now just rough shaking and vibrating start for about 5min (without plugging in block heater) or so then once warmed up she runs great.

I replaced my gpr on Friday night and my remote to lock the doors worked just fine. Saturday morning they unlocked just fine as well drove it thirty minutes and went to lock my doors with the remote and it didn't work. So could this just be crazy timing for it to stop working or could it be related?
I have a 2000 f250 4x4 I've tested with all three remotes I have for it and none of them work where would I start to test and see if it is just bad connections or dirty ones?

Here's what I'm dealing with. Took the truck on a 1500 mile trip with no issues. Got home and started it the next morning and it started right up. 1/2 mile from home it starts to run rough and wants to die. It does this for a few minutes and then perks back up and runs fine for however long the trip is. It will always re fire and have no issues. Every morning it's the same game as described above. Within 1/2 from home it's doing this. Seems to be fuel delivery related, but why would it start after sitting overnight, and then after its little fit, run without an issue?
No codes in computer.

2003 7.3 excursion.. The truck starts every time revs up and idles about 3 seconds then the rpms drop and it tries to stall out catches itself then revs backup and idles rough similar to if you have got air in the fuel lines from changing the fuel filter.. About 1 in five times the truck will stall out and it starts and immediately and idles rough but the rpms and everything runs at speed and rpms don't drop again! This is a reman engine/transmission recently installed.. The mechanic who installed it was unable to figure the problem out.
