Ford 7.3L Power Stroke (1999-2003) :: 2002 - Running Rough With Lots Of Gray Smoke
7.3 auto, starts and idles OKAY, drives fine if you have a light foot but trying to go faster than 50mph or more than 2000 rpm and the whole thing has an anxiety attack. Starts sputtering and popping, lots of grey smoke when it runs rough rough, let off the throttle and it MIGHT behave nicely again.
New lift pump, cleaned the pickup tube, fuel bowl fills nice and fast, just had my edge attitude juice tuner removed since it was causing similar issues that went away for the last 2 months, changed my IPR and CPS (had a mechanic test everything when the tuner was taken out, all injectors buzzed good, sensors good)
When this first happened after the initial problem with the tuner was resolved, it did throw the CEL, but I have since been able to get it to come back on, and my buddies OBD2 scanner wasn't even registering my truck when I hooked up... Dare I say PCM is to blame?
Ford 7.3L Power Stroke (1999-2003) :: Truck Act Like Going To Start And Black Smoke Coming Out From The Exhaust
I have a 2003 Superduty with 193k miles that is bone stock. I sold the truck to a friend and when he decided to not pay the remaining balance on the truck, I took back ownership. The truck was having heating issues and it set at a mechanic shop for nearly 2 years waiting for a diagnosis on the heating issue. Fast forward to the present and I now have the truck at my home. Heating issue was the radiator but this is no longer a concern. When I went to pick up the truck from the mechanic, the truck started fine. Every other day for the last 4-5 weeks I would start the truck with no problems.
I get the truck tagged and start driving it on a daily basis. I've put several hundred miles on it but the more I drive it, the less it wants to start. Now it's to a point where it only cranks but won't start. I can take a gas rag and hold it in the intake and eventually it will start. Once it's running, it runs great and has no issues starting. But once it sets for 3-4 hours, it won't start without some sort of assistance.
While trying to find the issue, I've found and repaired 2 fuel leaks and in the process I replaced fuel filter, air filter, replaced glow plug relay, replaced batteries, replaced CPS. Fuel pump is working fine. I've tried the ICP test and doesn't make a difference.
The glow plug light or WTS light works so don't think its the GP. The CES light was on. Had it scanned and it was the air bag sensor so no support from the CES.
While I was working on it yesterday and after cranking on it for 5-10 minutes, it would act like it was going to start and black smoke would be coming out from the exhaust. I let it set to cool the starter it fired up like it had no issues.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Excessive Smoke Coming From The Exhaust
I have a 2001 F-350 w/7.3. There was excessive smoke coming from the exhaust. So the first thing I did was to pull the glow plugs to see what they looked like. and while having them out I cranked the engine over. Upon doing so I noticed 1 cylinder putting fuel out of the hole. Meaning it was like you could put your hand about 6 inches above the hole and your hand would be wet from fuel. None of the other cylinders was like that. So what I did was pull the injector from the cylinder next to it and put it in to see if it was the injector failing. But it was still doing the same thing. What would cause this??

I was driving my bosses f550 with a 7.3, and while towing a loaded 40' flatbed of hay, it started bloing white smoke and lost all power and had almost no pedal feel. It wouldnt even go past 2500 RPM. Then, all of a sudden, it started billowing black, and BOOM backfired and shot flames out the exhaust. Then, I pulled over at a parts store and replaced the fuel filter, which worked for a while, but then it started blowing white smoke again. Once I limped it home and unhooked it, I took it out and let her rev a bit and it seemed to stop blowing smoke, but it still has less than the normal power it used to have. It has 226000 miles and is completely stock.

2007 F550 with the 6.0. About 2 months ago I replaced the EGR cooler with a Bulletproof cooler. Truck ran well for a few weeks. Then I started getting the "turbo fart". I stopped using the truck until I had an issue with another truck. I was stuck so I sent the 07 out without cleaning the turbo. This morning a decent amount of white smoke started coming out of the exhaust. The smoke would sometimes get a bit gray. Going up hill it didn't have much power at all.

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 F550 Turns Over / Black Smoke From Tail Pipe But No Start
Ok I'm working on a 2000 7.3 on a F550 truck was running but had no power so we changed out all the injectors and glow plugs and rebuilt the turbo now there is no start it turns over and were getting black smoke from the tail pipe. What is going on with it?
View 2 RepliesFord 6.0L Power Stroke Diesel :: 2003 - Blowing Gray Smoke On Acceleration
I bought a 03 6.0 dually a couple months ago. Got a good price on it. I use it very little, around town sometimes and used to pull a 7000 lb camper sometimes. My issue is, the other day I took off with the camper. Drove for maybe 5 miles then stopped and waited for traffic. When I took off again it was blowing gray smoke when I was accelerating and had little power. I was going about 30 mph for about a mile at about 3000 rpm up a very gradual hill. I was in the tow setting. When I got to the top of the hill it seemed to recover. I pulled over and shut it off then took off again without any issues.
The next day when leaving camping it was the same thing. Took off and saw gray smoke and had little power. After about 1-2 miles all was well again. Truck has 202k miles. Recently replaced oil cooler, egr cooler has been welded shut at both ends, turbo has been cleaned and all the filters and fluids are new. I have a Scan Guage 2 and monitored the ficm voltage and it maintained 47 to 47.5 volts. I know 2 injectors had been replaced when I purchased it as well and the egr valve by a dealer(they said it showed the cooler was clogging but like I said it was welded shut). What I should look for?
Ford 7.3L Power Stroke (1999-2003) :: F550 Runs Low On Fuel Pressure After Approximately 20 Miles Or WOT Throttle
Just joined today, I have a 2003 550 7.3. New HPOP, 3 new injectors, new seals on others, new fuel pressure regulator, new fuel pump, sending unit mod to eliminate filters. 733 HPOP pressure, 65 fuel pressure at idle. Truck runs out of fuel pressure after its warmed up and driven about 20 miles. Haven't checked voltage at pump while driving. I had taken it to a seasoned tech of 20 years and he had replaced HPOP and 2 injectors and it does start better but problem is still there.

I have an early 03 f350 with a 7.3 liter 298,000 miles on it
Replaced fuel filter
New oil change and filter replacement, New icp sensor .
Deleted the baffle and installed a cone air filter with the air sensor installed in the neck .
I Was driving home one day and the truck just slumped into this huge power loss . Couldn't get over 2200 rpms and barely made it over 30-40 mph.
Truck in park - idles like crap and still won't go over 2200 rpms when holding the pedal to the floor . And it has what sounds like a miss at a struggling "full throttle" (22-2500) rpms - thought it could be my icp sensor - replaced it -- no change
Checked driver side wiring harness -- no damage chafing found -- did a fuel can to pump test no difference - and today after I reinstalled the fuel line right after I ran my can to pump test I let the system prime . Started the truck and it ran for about 40 seconds and died and wound not fire back up and would just miss and spit and sputter -- lots of gray smoke though- but it fired up a few hours later after I let the batteries sit on charger .
Now before all this happened - I noticed the truck had a bit of a gutlessness to it as I would be piddling around around town and it would have this hesitation in power kind of like a slight jerking feeling , now this truck was so gutless since the day I got it ,I couldn't even burn out on a gravel road without the throttle going limp and the check engine.
Light kicking in so I figured I'd give it a bit of hotshots secret and see if It would maybe flush the injectors but it really made no difference...
Ford 7.3L Power Stroke (1999-2003) :: 2001 F450 - SES Light Came On Followed By Loss Of Power Under Load And White Smoke From Exhaust
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..
View 8 RepliesFord 7.3L Power Stroke (1999-2003) :: 2001 - White Exhaust Smoke When Letting Off Throttle
2001 SD F-250 SuperCrew 4WD, 7.3L (completely stock), 114K miles, automatic
We took Dad's SD for a 600-mile trip yesterday and today. The oil had 2000 miles on it, and we checked it before we left. The oil level was half-way down the hatch-mark, so we had added a little over a quart of oil to top it off, and I think that we may have added a little too much. Last night, when we got to the hotel and got out of the truck while it idled, a lot of white smoke that smelled like burning oil (like when you spill oil on an exhaust manifold) was fogging out of the exhaust.
It did this for a minute or two, then cleared up. All day today, on the way home (300 miles), about every time that I let off of the throttle either going down the interstate or stopping at a red light or stop sign, white smoke would pour out of the exhaust briefly, then stop when accelerating or in the throttle going down the road. What is causing this? Would too much oil (a little over a quart too full) make it smoke like this? The truck runs strong, starts and idles good, and no 'check engine' lights came on the dash.
Ford 7.3L Power Stroke (1999-2003) :: 2001 Started Blowing Blue Smoke
01 7.3 247k.
Yesterday went to get on the freeway I looked back and saw a cloud of what looked like blue smoke. I'm in northern Utah and it's cold but the truck runs fine, I haven't noticed any change in performance. Turbo still builds boost. I pulled the fuel filter cap last night to check fuel color and it was clean.
I do have the CCV mod done. I also pulled to IC Pipe off the turbo and there was a little oil in there but not much, should there be any at all with the CCV mod? Where to start.
Ford 7.3L Power Stroke (1999-2003) :: Slight Miss At Idle - White And Blue Smoke From The Exhaust
Early 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild

I have a 7.3 that's running rough. Started it the other day it ran alright but started blowing white smoke. Bought a oil and fuel additive i was going to run through it. Came a few days later, it stated up and was real loud and sounding like it was loping. It blew a good amount of white smoke, but it just smelt like real heavy diesel. Now i can only turn it over and it won't start.
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: White / Blue Smoke When Started Cold And Surging
Recently since the weather has been cold. between 0-30 degrees or so. My 2002 7.3 with 161k on it is smoking a decent amount i think. far more than i ever remember it smoking thats for sure! anyways its a combination of blue and white smoke and it doesnt last long when the truck starts maybe 1 minute and the smoke stops.
But I also notice when i rev the truck maybe around 1200 rpms the engine shakes very bad. so i was thinking maybe a glow plug went bad making the engine seem like its missing. but even when its warm i rev it up to 1200 and i still feel the engine shake slightly. Maybe im just being picky when its warm? I need to test the glow plugs and go from there but i want opinions about that issue. the truck sits for 4 hour periods and every time i start it i have smoke. I will pay attention tomorrow morning if it smokes after being plugged in all night and post my findings.
My other issue and this typically happens when its below 20. sometimes i will go to accelerate after coming to a complete stop and the truck kinda has a very weak rev to it then just takes off like the tps took a break on me. sometimes i have had it jerk the truck when the throttle catches and other times it creeps at first then takes off like a boost of power.
lastly and this little issue happens most noticeable at 35 mph. i feel a surging im thinking this is related to the tps but i put the truck on cruise control and i still feel the surging. maybe this ties into my second issue? bad TC? ive plugged in my scanner and the only thing jumping out at me is the icp hunts about 100 psi or more at idle. i plan on doing a WOT test on the HPOP, ICP and IPR tomorrow and see if maybe this is just a weak hpop causing my issues.
Repairs i have done:
new 8th injector and all new injector seals about 25k miles ago.
new ipr
new icp
have CCV mod done and 4 inch turbo back exhaust
new map sensor
cleaned out the EBP sensor and tube but that was probably 40 or 50k ago now.
gray cps and i cant remember when i put that on.
gutted the EBPV
bellowed up pipes
no tunes the truck is factory as far as that goes.
Ford 6.0L Power Stroke Diesel :: 2004 - White / Gray Smoke At Idle?

View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: White Smoke Blowing / Smells Like Fuel And Loses All Power
I am a mechanic and tow operator running a late 99 f350 7.3 6 speed cab and chassis wrecker. This truck has had a hard life and has been neglected for quite some time, and now has become my baby/headache. Truck starts great, idles nice, and will run great for about 5 minutes until it starts billowing white smoke that smells like fuel and loses all power. If you continue to drive it it will die. Sounds like it's dropping cylinders and will barely idle. If you stop for 5 minutes or so and let it idle it will smooth back out and will run great again for another minute or two, then right back to stumbling.
Using torque app, hpop pressure looks good when it's running well. Peaks at 3k, IPR maintaining 30-40% max. As soon as it stumbles you can see the hpop drop to 5-600 and the IPR will climb to 65%. Let it idea bit and they go back to normal, and stay good until it stumbles again.
Ive changed the fuel pump, ICP,rebuilt FPR, change fuel filter, pulled and cleaned the fuel tank (metal tank, no delamination, looks perfect inside). Pickup screen looked good. Cleaned the IPR, cleaned the hpop reservoir, there was no screen inside. Checked voltage at fuel pump, 11.78 across the pump with it running. Pulled valve covers, no noticeable leaks around injectors. Injectors have less than 5k miles. Remans with 100% larger tips.
To me it seems like the lpop is not keeping up with the hpop under load, starving it until you idle and let it catch up. Could it still be bad injector orings? Bad lpop? Something I'm not thinking of?
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Oil Coming Out Of Exhaust
Recently I came across a guy parting out his F-250 with a 7.3 powerstroke. Said it had a blown engine, and didn't know what was wrong, but oil was coming out of the exhaust.
My question here is why that's happening. I don't have any experience with the powerstrokes, so I'd like to know what the culprit is before I even consider buying it.
