Ford 7.3L Power Stroke (1999-2003) :: 2001 - Hard Start With White Smoke - Bad Injectors?
May 3, 2016
My 2001 7.3 was smoking excessively and I rebuilt the turbo and the center cartridge was at fault for that. I'm still having some of the problems I was having before with a lot of smoke at cold start (I have to hold the accelerator down while I start it and it takes about 10 seconds to start) even when I hold it I have to keep it held for about 5-10 seconds before the RPMs get to where they should be. And it smokes like crazy.
Then after about 3 minutes warming up, or 30 seconds of me holding it at 3500 rpm, the idle smooths out and it only smokes a little. Then once I start driving it doesn't smoke a lot unless I go hammer down then it puffs some white smoke. I took the oil cap off and it isn't huge amounts of blow by cap just rattles off. Can ford buzz test and see if I only have 1 or 2 bad injectors? Could this be anything other than injectors? It has a ts6 on it with 24xxxx miles with factory injectors.

I have a 2001 7.3 with 243k. I think the injectors are shot but other people including a local mechanic say it's not the injectors. What the truck does is smoke white. Sometimes little puffs when accelerating. Sometimes clouds that make the people behind you drop back a 100 feet. I have a ts6 on the truck and that alone with the 243k miles is enough to think its bad injectors. It smoke white. The exhaust is moist to the touch with soot built up like crazy. It doesn't really smell sweet and it's not really blue at all. It's getting horrible mpg. And lacks power. I don't have a high enough psi gauge to test compression. All arrows pointing to injectors?

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?

My 2002 F450 7.3 won't start unless the heater is plugged in for 2-3 hours+ regardless of the weather. Today I did a cylinder contribution test and at first cylinder 2 got code P0266 (Injector Circuit Contribution / Balance Fault) and cylinder 7 got code P0281 (Injector Circuit Contribution / Balance Fault). I drove it 10-15 miles and did another test. Only Cylinder 2 got code P0266. No error on cylinder 7. I've used RevX with some success before, so I'm tempted to try it again see if it clears up the error on 2. My question though can injectors be an explanation for my hard start situation? (I've already replaced EGR, ECP, Fuel Filter, CPS and glow plugs seem to be fine also).

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.

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.

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.

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. 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.

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

So I was on my way to work on a semi-chilly morning here in Colorado. Every day as usual, a little upset in the morning, a little white smoke and after a good warm up i'm on my way. About 10 minutes up the road while accelerating on the freeway, I hit I guess the perfect RPM range (2000-2500) when all of a sudden my CEL came on. Right as the CEL showed up, the engine introduce to me a new skip and lost a bit of power. About 5 more minutes up the road, the CEL went off and the skip went away, unless in idle. I made it to work a few minutes later and the skip in idle was apparent for sure. I turned her off and just couldn't get her to turn back on. The injectors are just not firing, no smoke at all, they don't even sound like they're trying to fire almost like no signal to the whole engine.
I replaced the CPS, the IPR and unplugged the ICP to test if she'd go. I opened the fuel bowl and watched it fill up. I checked the HPOP level, it was almost full, maybe a quarter (between half) inch from the top. No codes.
She ran great until this, outside of needing glow plugs. When I was trying to get her started it was 60ish outside so I don't think glow plugs is the issue. It sounds like the Injectors are not firing at all, whatsoever.
I will note that I had a few fuses blow out of no where that I replaced, a trail light, OBD fuse and one other in the under-dash box. I had her dyno'd a few weeks back and the tech said she made great power but sounded like she had a little issue recovering from the high RPMs but I figured my injectors are tired.

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..

my 2002 7.3 with 370k just started to puff a small cloud of white smoke on start up. i realize this is normal during cold months but it is currently 102* in Texas. it will do it on the first start up of the day or if i start it immediately after shutting it off at full operating temps and when i do get a smell of the white cloud it has a oil smell but this only lasts while the cloud is dispersing all of that only lasts about 2-3 seconds no loss of power good boost pressure when driving no rough idle at all nothing acting any different other than the cloud and the quick smell of oil...

Fine one day, no start the next. Been skimming over the 7.3 no start thread, so w got some ammo for him to check. White smoke while cranking, rpms move while cranking. Nothing to read codes or other sensors YET. Tried the unplug ICP and it "wanted" to fire. So, I have him my spare IPR to try. I'm sure he checked the fuses but will confirm via text...

My beloved excursion is 300 miles away from me in a no start condition. Vehicle has 270K miles. Very well cared for. No issues to date since purchase 5 years ago. Went to back up and the vehicle starting Caming like it had a big cam in it. went from reverse to drive and problem went away. Drove vehicle for 2 more weeks without issue. Then all of a sudden it dies. Restart driver on down the road 1/4 mile, dies again. Restart, make 45 mile drive home vehicle is low on power will hardly pull a grade but I got to my friends house. Went to start vehicle next day and no start. Puff white smoke while trying to start. It hits every once in awhile but wont run.
The vehicle is throwing NO CODES other than an open glow plug on 1&8 which it has for sometime now. I have changed, fuel filter, fuel pump, CPS(genuine ford), IPR and IPS. No real changes still wont start. I disconnected the IPS and it started but it sounded like it was only running on a couple of cylinders. It would not accept throttle. The local Forddealer does not have a Ford diesel tech. Ive called a couple of diesel shops and I hear could be a bad HPOP, or bad ECM or a bad IDM but without seeing it. I am at my wits end with this thing. I am an electronic engineer by background. So I have a good sense of the process. I have checked all fuses, relays, etc. I will say I did have one issue with it a year ago where the UVC problem popped up but the dealer fixed it and it has been fine ever since.

I had some starting issues a little bit ago, but got those sorted out- I installed a new ICP a few days ago and haven't had any more issues. We came up to the mountains last night (got down to about 35), and now it won't start this morning after 3 GP cycles. So I tested the GPR, and the always hot post was, well, always hot. I tested the other post with ignition on, and it had nothin.
Luckily I had a new GPR, so I swapped it out and everything tested normal on both posts. Still won't start. I'm getting white smoke so I know there's fuel (plus my pressure gauge is at about 58 psi). What else am I missing? I've also tested all the fuses....

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.

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.

This is kind of strange, I have a hard start problem, when I crank it the first time, it fires immediately, kind of like a romp, but doesn't start, then when I crank again I get a lot of whitish smoke and no start. I read to try and unplug the ICP and try it. That worked, and I had oil in the connector. I replaced the ICP, but have the same problem. I still have to unplug the ICP for the truck to start. When it does start, it runs great! No injector stiction, no smoke, no rough idle, it runs and sounds great. Why unplugging the ICP is still required to start? (Only after sitting for more than 10-12 hours).

My 2001 7.3 is smoking only when barely on the gas. New fuel filter. Don't know if its possible injector going bad or what? Smoke is white not black.

I have a Tymar intake, magnaflow exhaust, a DP Tuner and I have Rosewood Diesel injectors.
I had a bad oil leak recently and it seemed to be coming from the turbo area so I changed all the o rings back there and deleted the EBPV system (I cut out the butterfly and welded the holes shut, cut the part of the pedestal that held the actuator because it looked like it was leaking and welded the oil holes in the pedestal that fed it. I left the actual EBPV sender in the pedestal and kept it connected to the harness)
After all that was done I checked the oil and it was low but still on the dipstick so I drove it to the local parts place to get some more oil, about 2 miles, because I wanted to check for leaks. It was not happy, ICP low code came up it was sputtering and jerking when stopped at a light. I got to the store and parked it, it took about 3 litres of oil and seemed to run pretty good after that.
But on the way home I noticed a bunch of white smoke, I figured maybe an injector was stuck. I started it a little later and no white smoke in the driveway so I thought maybe it had gotten lubed enough and had sorted itself out. That was a few days ago.
Today I started it and let it idle in the driveway for about 15 mins and no white smoke, I wanted to get it up to speed a little so I took it to do an errand that was about 10 miles away, lots of lights and a bit of highway. It would run fine while going at speed but as I would slow down for a light the ICP would go down to around 600psi and the white smoke would start, as sitting idling a huge cloud of white smoke would form (yes, I was that guy), once I could take off and get it running a bit harder it would go away again.
I am assuming that I have a stuck injector (or cracked), I have no oil in my degas bottle and it doesn't look like it is fuller than before. Seems like I may have used more fuel than I should have, but pretty hard to tell just from the fuel gauge.
I have tried a buzz test and they all sound the same, tried a Compression Contribution test, no codes from that.
How can I locate a stuck injector? If that's what it is?

I have long been having troubles with white smoke at startup, even when its 90 degrees out. Long story short I've got new glowplugs, GPR, UVCHs, valve cover gaskets, injectors, turbo, valve seals, valve springs, and HPOP all within the last year. Most of those parts were needed, some maybe not so much. After installing injectors things started getting worse, whether they're related or not I'm not sure yet. I pulled passenger side valve cover off again in an attempt to figure something out and heard this coming out of the intake spider.
[URL].....
The strange thing is it goes away when it warms up. I should also note the reason I started with the passenger side is because I did a compression test and this side had the lowest readings, with #5 being 270 psi. I disconnected each injector one at a time on the passenger side to see if it made a difference while running but didn't really notice a difference. Am I looking at a motor rebuild, or at the very least a head removal?
