Ford 7.3L Power Stroke (1999-2003) :: F250 - Lots Of Smoke On Start Up
Mar 28, 2017
Alright. 99 Ford F-250 4x4 Ext Cab 287,000 miles. I know she is getting a little long in the tooth but this issue is new within the last month. It does seem to be better when it has been plugged in. On start up I smoke out the neighborhood. Blueish/White smoke, also sounds like it's missing on a couple injectors. Doesn't matter if you cycle the glowplugs a good long time. No luck. Glow plugs are 1 1/2 years old along with injector o rings. Only thing new is I changed from Rotella T-6 to Delo 5W40 Syn, but it was doing it before the switch as well. I tested my glowplugs relay and that is working fine. Could I have lost a UVCH? Fuel filter six months ago or so.

1999 7.3 misses when starting it cold (first start of the day even when outside temps were around 20 deg C ). It has a noticeable miss and lots of white smoke. After warming up it runs perfect. I changed the GPR and tested all glow plugs, 3 bad and one weak one all replaced. Now that it is cold out it still misses when first started, even if left plugged in.
It will start and run for approx 3 seconds perfectly smooth then it starts to miss and idle speed slows down. on one occasion I went to start it after sitting 10 plus hours plugged in and it started then missed and slowly died. Would not re start, It was firing and smoking but not enough to get going again. Went back the next day and it started and ran fine for a few weeks. Did the same thing to me yesterday, started and then petered out and died and this time it will not re start after 2 days of trying on a couple occasions. I changed out the CPS with no luck.

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?

Just bought a 02 f-250 7.3 with 115k miles. A couple days after I bought it I noticed a lot of white smoke on cold starts for about 20-30 sec at 50 degree temperature. So I tested the GPR which ended up being bad a replaced with the one that is double in size(name escapes me atm) and also did the 50 cent mod to keep the through-valve cover harness from losing connection since both sides were lose.
After that the temp warmed back up and it would only blow a "puff" of white smoke. The past two days it has gotten down to 30-32 and the truck has a rough time starting. Cranks fine but it's almost like it's getting choked or flooded then it will blow smoke for 3-4 minutes after it starts. The truck does have a FASS fuel system on it with stock injectors. Should I try to Ohm out the glow plugs again or where should I start trouble shooting?

I just came back from a 200 mile trip and parked my truck. Next day, got in the truck and turned the key.... it turned over and white smoke coming out the tail pipe. After doing some research(you tube),I ruled out cps sensor because it was showing low rpms on tach. Replaced glow plug relay and still have same issue.. what else to look at that I can do without getting it towed. Hunting season coming soon and I need the beast.

I have always seen other trucks blow black smoke with towing up a hill but mine for the most part has not. I pulled my 5er to CO this summer and notice my truck starting to blow black smoke. I consider myself a very conservative driver. I always stay around 65 MPH while towing and never push my truck up the hills. I always try to keep the RPM around 2000 and let the MPH fall where they may until I reach the summit. With the black smoke I'm starting to see what is my truck trying to tell me? It's not bad but would like to fix now before it becomes something more.

So this morning, I stopped for fuel. My low fuel light had come on yesterday, so I planned on filling it up this morning. Swung through the local Safeway (my usual fill-up haunt) and threw 25 gallons of diesel into my Excursion. Truck started up right away, like always, pulled around in the parking lot, pulled into traffic, then got stopped at a red light. I noticed a slight unevenness in the idle for a couple of seconds, then the light turned green. Pulled out, truck accelerated a bit more labored than usual, and in my passenger's mirror, I looked back and saw some light greyish blue smoke.
The smoke progressively got heavier, power diminished, and I was no longer able to maintain speed with traffic. I pulled off onto a side road, shut the truck down, and scanned for pending codes. Nothing. So I hoped that it was just a gremlin, started the truck again, got tons of the same smoke, really rough, super clattery idle, and the engine wouldn't even accelerate in park. No hint of boost, nothing. So I turned the truck off, called a tow truck, and had her flat bed hauled home.
Background on the truck, roughly 150K miles, changed the fuel filters not too long ago (less than 7K on them), recent-ish oil change, but I was planning one for later this month. Truck is all but stock, only an aftermarket cold side intercooler tube. I recently replaced my EGR valve, less than a year ago, because it was stuck partially open, replaced it and the truck ran great after that.
I've been seeing some scary writeups for similar things, stuff involving cracked pistons, bad rings, engine teardowns, new engines required, things like that. For me, it just seems like a ridiculously convenient coincidence that the problem would happen immediately after refueling the truck. At this point, I'm planning on replacing both fuel filters and doing an oil change as preventive maintenance and as the easiest possible fix, but what else should I be looking at? Some posts suggest FICM, some suggest ICP sensor, some are saying my injectors may be shot.

Today I was riding along and all of a sudden I noticed a loss of power. I look in the rear view mirror and get into the pedal and a lot of black smoke. When I get to where I'm going and stop I noticed the idol was a little loopy. I never saw a check engine light. I have the Edge insight. I had two codes. P1000 OBD System readiness test not complete. P2290 ICP TO LOW.
When I would reset the codes the P1000 came back instantly every time. I parked the truck for about an hour. When I started it back up everything was normal. The power was back and no smoke. This happened two more times throughout the day. I have heard people describe a sticking EGR Valve causing these symptoms. Is that where I should start looking or is the ICP the culprit or something else?

Have a pretty good running (I think), 2000 7.3 with 151K that has always been pretty noisy. Lots of clatter. I amjust wondering if there's an easy way to tell if I may have injector issues starting to come up.

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....

Well, today i had my first bout with tranny issues of any kind either before or after my BTS installation. After sitting all day at work, heading home, the shift i guess from 2-3 at about 40-50 mph shifted really hard, BANG. Heard a whirring/whining sound, lots of slipping with the TC. After a lil ways it was like it was in neutral.
Coasted to stop. Went thru the gears from park, rev, and drive about 3 times, got movement each time. Got out, looked for obvious, no fluids or linkages apparent. Drove thru town about 25-30 mph. Felt like it was "hunting" and shifted like a manual grinding gears. Got on highway and no overdrive and im thinking no high gear either.
Push button on shifter light changes, but no change in operation. Running 60 and rpms are turning 2700ish. Still "hunting". But while hunting it isn't wide rpm swings, just a small amount, not wide enough for a gear shift. I am thinking that its torque converter constantly engaging and disengaging.
While letting out of gas it coasts down with TC still locked up all the way down to about 1100 rpm before unlocking. Then I start seeing the OD light flashing. Ok, classic wire chafe in steering column. But it doesn't always flash, only sometimes. And fuses are good. Temps never got above 150 during this 50 mile drive.
So i get home (and its frigging dark already, i hate that this time of year) and I log on and start reading up on this again to refresh my memory. I had called Brian over at BTS when it happened as i was going down the road, he was busy at time. He called me after i got home and i explained and he talked me thru some things. Wanted me to pull the codes and get back with him tomorrow. I did that and the screen shot is below. I will talk more with Brian tomorrow.
But during some of my reading i think i came across some others that had similar trans codes and the issue ended up being the alternator. Alternator ? For trans issues? Is that right? I guess stranger things have happened. I have a high output alt waiting to be installed but haven't yet. I guess we shall see. Brian thinks it something telling the TC and trans to act that way. Doesn't think anything mechanical, yet, leaning towards electrical.

For the past few days I noticed my truck would be really rough to start and a lot of white smoke. but once it ran for a minute or less it would be fine. Today when I got home I popped the hood and was looking for anything and noticed my degas bottle had this weird fluid inside on top of the coolant? So I popped the cap off and smelt it and its fuel. Of course this would happen to me. Now I'm not going to lie I have beat on it a few times this week but nothing so so serious.
Could this be contributing to it? Could it be a head gasket? now being a diesel mechanic I doubt its a head gasket simply because there is no oil mixing. I am praying its nothing too major. Once I have the narrowed down to what it could be ill see if its something I could tackle or if the stealership has to do it, which I am not looking forward to. I'd rather be down a truck for a little bit and save a boat load of cash.

Steering wise, it seems very likely that I'm due for a steering box. Lots of slop when I turned the wheels back and forth. Also, as per the seller, it seems like the the wheel bearings and ball joints are in good shape.
The sway bar end link bushings are smoked, so those need replacing. As for oil leaks. I'm thinking it would be best to pull the motor. It looks like this engine has had the pan off, but I do believe I have a front pain leak. The crank case breather is going into the intake which is annoying. And I believe the intercooler is full of oil, explaining the mystery oil leak by the passenger side intercooler boot.
Couldn't see any oil in the valley of the motor but I see oil coming down the down pipe of the exhaust, out the bell housing of the motor and dripping from a weep hole maybe 8 inches down the transmission as well? Seeing as to how I'm not sure what clutch I have, it make sense to pull the trans. And If I have the dreaded oil pan leak and a intercooler full of oil, why not just pull the motor? I'd also like to trim out the front panel for 05+ head lights and clean up the wiring on this thing. Found a cheesy electric compressor for a small horn. Sounds like a clown horn, no kidding.

Here's the deal. 99 Powerstroke out new injectors and orings. Did orings twice to make sure i didn't damage it. New turbo, new utvc gasket, new ipr, new fuel pump, I new complete engine wire harness. I pulled the injectors and ran in another truck no problem. New injector cups compression was all in the 300-375 range. Any cold start smokes like hell. Goes away when driving after the first time of hitting boost. Spits and shudders for a few seconds until boosting. Every time I stop it starts smoking again at idle. No power loss not using oil. Can't get a grasp on this smoking issue. When cold start I kill millions of mosquitos in a one-mile radius.

2000 F350 with 340000 on it, have had it for the last 140000. It's an old service truck from south west gas with one owner in between them and me and he put about 5000 on it. I have the big cylinder open air filter, billet compressor wheel, 4" exhaust all the way and an Edge tuner. Don't have any codes I can pull with the tuner. Have been good to me so fare only need regular maintenance, but always had smoke out oil filler with a little pulse.
2500 ago I changed oil and add 1/4 of Lucas oil. 3 days ago when I started in the morning it smoked white smoke out the exhaust as a steam train and idle rough, but cleared up as I went down the street and will do so every time I start cold or warm. Ok, might need new GP, did that yesterday yet the same. Now I start checking stuff and have smoke out the oil filler as a steam train so the cap won't stay.
I know it sound like alot of problems, just try to verify some of them. The smoke out oil filler is blow by? The smoke on start up is that related to bad injectors? Can a bad injector dumping fuel create the blow by? Coolant level ok Transmission fluid level ok Engine oil Rotella T6 added 3 quarter in 2500 miles. I do not have a scanner or any other advance test tools.

I just replaced my up pipes, turbo pedestal O-ring, ICP, IPR, New O-rings in all my injectors and torqued to spec, new glow plugs, glow plug relay, oil loom wiring harness, new O-rings on oil cooler, oil filter, oil, and antifreeze. I have tried and tried on upwards of 75 or so time to get it to turn over. A little white smoke came out and it sounded like it wanted to fire up, but only a few times.
I have good batteries and a charger on it, 3-4 tries in 5-10 second bursts or longer if it doesn't lose power every 30 -hr. oil is in HPOP too. just found out my block heater is dead, but I shouldn't need it now. Tach moves a little when I crank it but only when my oil pressure gauge hits half way and that about the time it wants to start and starts white smoking.

So I've been having issues with starting my truck lately. It was really hard to turn over, would start really hard when it did and would blow some black smoke. Turns out my starter was bad so I replaced it with a DB Electric high torque starter. Now it starts up great... for the most part.
I'm still having some black smoke when it's a cold start and/or I have the key set to "On" to warm the glow plugs for a few seconds. It's almost like the starter is turning over the engine, but for the first few turns it sounds empty or hollow (at least that's the best way I can describe it). After the first turns it will sound normal how it's supposed to and will fire up shortly after but with some black smoke.
If my car is already warm it cranks right up without any smoke unless I have the key set to "On" for a few seconds to warm the glow plugs like I said earlier. Pretty much if I warm the glow plugs it makes it harder to start up for some odd reason.
What might cause this or how to fix it? Maybe some of my glow plugs are going bad, or possibly my IDM? I used to have the P1670 code by itself, however, that went away when I replaced the starter. I also just replaced my camshaft position sensor just to be sure it wasn't going bad. I've also been having some boost pressure leaks if that's relevant at all.

When it is cold out side like 20 degrees I'm having problems starting my 2000 7.3 I'm cycling it about 5 times and misses smokes white for a bit then stays running I was thinking of changing out the fuel filter. What it could be?

I noticed about 1 year ago I had diesel in my coolant but wasn't sure.. took it to a Ford Guy about 45 minute's away.. He seems to know his stuff but when he tested the coolant the results said less than 2% diesel.. But he did find an injector issue and swapped it out..
Forward to present.. there is diesel in my coolant now , since the level is rising to almost overflow and I believe this has been doing on for quite some time as I have that smell you get in the cab..
BTW - All injector cups have been done about 3 Years ago.. On another note , I get white smoke on start up especially if the truck has sat for a day or 2.. What can cause diesel in the coolant.. I did a complete coolant flush this summer and was super **** about getting all the old coolant and gunk out.. Ended up with only clear water coming out the degas
