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...
View 9 RepliesWas driving to work about 4 miles into my travel rolled around corned and she died..... tow bill and cps she fired rite up. Ran at idle in drive way because I was a little leary for about an hour left drive way went 2 miles went to pull in to store died again. Another tow bill and 2 more cps still won't start rpm is only like 200 when cranking but sounds like a lot more. The wts light works, batteries are pretty new, cps in new...
View 6 RepliesThis 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).
View 9 RepliesFor 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.
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.

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?
View 6 Replies99 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.
View 6 RepliesI 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.
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...
View 14 RepliesMy 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....
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 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.
View 14 RepliesMy 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.
View 1 RepliesI 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?
my 2000 f350 7.3 is acting strange lately. Its got 252k and is all stock other than exhaust,intake,ww2. It smokes white every random once in a while for some reason. At start up it wont though. If i get on it every once in a while it will smoke white then go to back to black. Im not consuming coolant, and the oil looks fine, no residue on the oil cap and its not puffing out the oil cap either. Other than that its running great just dont know why it goes white every so often.
View 14 RepliesWhen my 99.5 SD is cold ( 50-60 f) it smokes a lot of white horrible smelling smoke for the first 2-4 minutes. If plugged in the block heater it doesn't do it. Also when cold, when you accelerate the SES light comes on until you let off on the throttle then it goes off. Even going 10mph in low rpm? Once engine is up to temp it doesn't do it anymore. It seems to run fine otherwise. I do have 2, 700 CCA Napa batteries that are from 2011 which I plan on replacing next month with Motorcraft Maxx 850 CCA.
I have replaced the UVCH, CPS, Fresh Oil and put additives in my fuel. I have even disconnected my DP Tuner F5 and it still does it. I have AE with ford bundle and it seems like my HPOP seems to be working fine as well as buzz test and glow plug. Could it be an injector ( I have stage1 casserly from full force)? What about a sensor not working? It has always smoked since I have had it ( about 3 years) but the SES light issue has only been happening since my IDM was replaced and I had a mechanic work on it.
SO, I've owned a 92 f250 7.3 for 10 years and it's got over 340k miles on it. Well, she is getting tired so I'm debating replacing the truck with a SLIGHTLY newer model.
I've found a truck that is a 99 7.3 powerstroke with a 6 speed manual and 260k miles. Knowing these engines I feel this truck has at least another 100k in it if the thing was somewhat taken care of. The issue is that the fella that has it for sale says it ran great for years and one day started blowing white smoke while driving. Other than this new issue it runs fine.
So my question is, what could be the issues causing the white smoke? I always thought white meant unburned diesel or maybe antifreeze. Head gasket comes to mind but it's not something I've ever dealt with.
I like that he parked it when it started having issues. Sounds like someone who doesn't completely trash their vehicles. Too high given the condition? Truck looks and sounds pretty good aside from the smoke, pretty reasonable condition.
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?
