Ford 6.0L Power Stroke Diesel :: Slow / Now Cranking And Puffs Out A Little Black Smoke
Jun 5, 2016
So about a week and a half ago I went to crank my 03 6.0 truck up after having driven it to the mountains (about a 5hour round trip) several days ago. It was a little slower than usual but nothing too alarming, got to work and worked a full day, came back to my truck and it took even longer to crank. Drove to my girlfriends house to pick her up, only had it shut off for like 2 minutes hot and when I went to crank it it took two tries. From then on it was only bad at cranking when hot but now it takes 5-8 tries to crank whether it's hot or cold.
I took it to my buddy who owns a diesel mechanic shop and we hooked it up to his computer, everything checked out just fine, oil pressure was good, so was all injectors and ficm voltage, no red flags at all. So I went ahead and changed the icp, nothing, then he told me to change my aftermarket oil filter to motorcraft oil filter, still nothing, I also changed my oil filter drain valve and nothing.
When I'm attempting to crank the truck, after I hold the key attempting to crank it for maybe 8 seconds my oil pressure gauge jumps to normal. I have an ipr on the way to my house and I'm gonna try that as well. Also when the truck gets running it runs just as it ever has, no weird sputtering or stalling or cutting off. But when it does finally crank it puffs out a little black smoke.

My truck is an 03 and I changed number 5 injector and number 4 injector, checked my ficm everything is good there now I have a contribution balance code for injector 4 now injector 5 and an EGR code some guys on hear before said it could be a sensor but today I talked to my mail man who also owns a 6.0 and he sounds pretty knowledgeable he says it's possible that it could be that the computer is not reading out right and those cylinders are getting to much fuel for an instant that's what's causing the sudden puffs of black smoke. My torque pro is giving me all these codes and I'm starting to think that there is something underlying....

Title says it all... Starts & idles pretty good. No codes. Has decent power on mild acceleration, any time you step on it more than 1500rpm it lets out little black puffs of smoke and intake makes that popping sound and truck jerks a little...EGR delete. HPO pressure is good. Injectors are fresh as of a year ago. Valves? Lifters? Turbo?

My truck has been having this issue pretty much since I have had it, but it seems to be getting worse, or so I think.
When the truck is cold, it does not want to move very well. Like it's missing, and it does this until it gets warmer. Also, I have puffs of blue smoke come out the tailpipe when this occurs with it cold.
Injectors? Injector o-rings? Stiction?
FICM volts are good at 46.5v-48v when cranking.

I have a 1994 Ford Ranger with 4.0 V6 Automatic. The problem is when it idles it idles low and surges up/down and pushes a very small amount of black smoke puffs and smells like gas. I have installed new coil, new wires, new plugs, new ect, new crankshaft position sensor, and new maf. It has new intake manifold, new injectors, new alternator and it still does the exact same thing. Nothing is phasing it. I ran the key on/engine off test and got egr codes and a map sensor code, then ran the engine running test and got 998 and 126 code. The 998 code says that its basically a hard fault/ have no idea.
I do know this is a donor engine out of another year not sure what year, but i know when i ordered the coolant temp sensor the only ones that would plug into it are the years 1990-1993. Now here's my other question, why would the computer give me a map sensor code when truck doesn't have a map sensor? It has MAF sensor, and why egr codes? The truck doesn't have egr and never came with it. I do know I've unhooked battery and replaced the maf and its like it doesn't even recognize it? Could it be the ecm/computer bad or needs flashed?

Started with lots of black smoke all of a sudden. Not under any significant load at that time. Reached destination (barely) and started the search. Have taken off blue connectors on CAC passenger side. Top is marginal but see no holes. Pulled the MAP hose and see nothing unusual. Have not checked the driver side CAC or the BPV sensor. Have a ScanII device that shows no codes. Got my other scanner and it too shows no codes.
Had it towed home over 100 miles 'cause now it just barely runs. Idles fine but have a engine noise change (deep and hollow) every once and a while at idle. EGR leak? Doesn't blow black smoke anymore. More of a white/blue. Exhaust smells odd. Absolutely no turbo activity. When shutting hear no whine down of the turbo. No boost evident on the dash or on the scan II. I am at a loss at this point. Will check fittings again.

6.0. 115,000 miles. Everything stock, except bully dog intake filter.
I replaced the FICM recently, with one that I bought from the guy who makes those cool You Tube videos, Diesel Tech Ron. I also replaced the EGR valve. I also replaced the intercooler boots on the hot side. I cleaned the intercooler pipes. I cleaned the intake filter as well. I'm still blowing out black smoke, if I floor it when I need to pass someone.
Follow up question: I bought those boots from Riff Raff Diesel and I bought new clamps, too. I'm not sure if I installed correctly. It's already blown one off (it blew the top of the intercooler pipe off, by the turbo, but the boot stays on the turbo) and I put it back on and tightened it all the way down, and I've had to re-adjust 2 times, now, since it acts like it still wants to slip off. Do I simply have the other ones misaligned???

So I started to NM from fort worth texas with my 33" camper blew my CAC pipe four times. Finally got there. In the morning it took longer than expected to start. When it did white smoke. That was replaced with black smoke under full throttle.
I went from elevation of 700 to 8000 Ft. Should I care about black smoke? Meaning should I take it to Ford and get a rental car to get it looked at for our trip home.
96 degrees towing at 70mph with lots of climbing mountains.

1st Ford was an '08 to '10 model F250 6.4L that had an engine fire on I-82 towards Ellensburg in the passing lane.
2nd Ford was a 2005 F-250 6.0L at Vantage, he had black smoke coming out of the exhaust and a terrible engine knock, and was pulling a 32 ft TT. When I went to go talk to him, he had no idea what a ScanGauge was or anything about the truck.
When I looked at the engine bay with him I saw the EGR valve had been deleted with a block off plate and not plugged into the fan hanging on the side anywhere, he had the high rise aftermarket oil cap installed, ALL the metal/aluminum parts had bad oxidization. He had no gauges whatsoever.
Then to top it off, he said he was going to try and make it to Ellensburg while pulling his trailer. I told him he had a 4% grade for 10 miles in front of him to climb, and the another 35 miles after that on flat ground. All I could feel was, "is there any hope for this guy"?
Anyways, my question is, without any gauges, what would be some good educated guesses with the black smoke and knock? I am mostly just curious what this guys issue might of been with his truck since seeing the symptoms first hand.
My thoughts are the oil cooler leaking, and making the injector(s) stick open.
Of course now that I think of it, there's probably too many scenarios to mention.

Driving home 2003 6.0 started blowing a ton of black smoke, cars wouldn't get behind me. Found an exhaust leak on the driver side up y pipe. Would that cause this much smoke? 2 codes were 0284 and 0281, I replaced those injectors about 10k ago, at the same time replaced turbo, hpop, egr valve and cooler delete, and new oil cooler.

Found a 2004 Ex, Eddie Bauer edition says it has injector issues, blowing black smoke........ It is apart cause he thought it was the EGR. Has 245,000 on the clock. If the body is super clean I'll give him a offer, it's going to get a motor either way and I'll have my Ex back.............I really miss that truck!

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?

I have a 2003 with 150k miles. My 6.0 has black smoke and can barely crawl up a hill. Dealership is 30 days out for an appt. Air filter, oil change, alternator, and batteries are new. I removed the EGR valve and cleaned, but the valve seat is not perfect. I can see 20 to 30 mil gap around half of the seat. Is this ok or will that little gap cause this?
Hoses all look good. No alarm lights. I have no diagnostic tool but I can use a meter well. It did have an airbag light but I found the fuse missing and replaced it. The air filter alarm switch fell apart but I bypassed it till I get new part. No alarm lights now.

So I am not sure exactly what is going on with my truck. It is a 2004 F250 has a 6.0 L. Sometimes when I take off from a stop the truck has no power and blows some black smoke. Then the turbo kicks in and all is fine. It comes and goes when it pleases no matter the temperature. What started happening is when I drive it a steady pace on the highway sometimes the turbo gets quieter and louder and quieter and louder sometimes when it gets quieter I see a little bit of black coming out of the tailpipe. Sometimes it doesn't do it at all. Also sometimes when I let off the gas the truck sounds like it's trying to laugh at me like a wastegate is fluttering.

05 6.0 deleted and studded. 170k fresh filters and oil, no CEL or codes.
This has happened 3x in months, so it intermittent. Truck will start fine cold, except for this last episode ....
Truck starts right up, idles correctly, speed bumps up if its cold enough to trigger the high idle. About mid way through its warm up, at approx 130-140 idle falls off, barely runs. Almost knocking. Black smoke if you give it throttle. Has no power when its doing this. Truck will not move and almost dies in gear. Give it til 185ish degrees then pooof! All good.
However 2 days ago it wouldn't start. Cranks but won't catch. Stumbles and dies. Finally got it to start after setting the charger on it. I killed it. But this time when it started it was straight into its rough idle, no power...until about 180. I switched it off, restarted it and it was totally fine
Ficm is 47-47.5. Every now and then I see a 46.5 for a split sec
Hpop is 700-800cold cranking.
Not sure what else to look at.
Moto craft filters.
Amsoil 5w-40
Archoil in the fuel and oil
Twc3 at every fill up.

During an out of town trip today, 6.0L 2006 started burning black smoke when accelerating. Was bullet proofed in 2013 without replacing injectors. Running a SCT programmer. After getting home I connected the tuner and didn't have any DTC's. Checked the oil, didn't smell any diesel on the oil stick. I was running the street tune, so I changed to the performance tune and it doesn't seem to be smoking as bad. What could be going on? This site has always came through for me (a non mechanic) when troubles start.

I have a 2004 f250 i purchased a month ago. Its been cold in Denver this last month which is why I didn't mind it much. But now that its been in the 70s im concerned. Its always the first start up that it acts up. I go to turn the truck on and it starts idling for only a sec or two, then shuts off. I crank it about 3-4 times before it actually comes on and stays on. There is black smoke not white smoke once it starts to idle. Once idling it stays on and drives the way it should. If i try to start the truck again it will do so with out hesitation. I just did a tune up at grease monkey including fuel filters and oil filter. again its the first start up always.

Black smoke is bad I think, especially when I push on the gas pedal, and I hear a bad whine or something that sounds like a very loud power steering pump whining.
I also have zero on the boost gauge. The truck barely pulls itself back home and black smoke is dribbling out of the exhaust pipe.

I have replaced the EGR over 1 month ago and also replaced the MAP sensor also as it was bad. I also have a Scan gauge, for monitoring.
The problem is once the truck gets to OT and the valve opens I have heavy black smoke on take off?
