runs rough and blows white smoke on startup

[jwsailor]

my 2006 5.9 (15K miles) began running rough when I started it cold(70degrees) and blowing white smoke about two weeks ago.

I took it to the dealer, they could find nothing and of course it didn't do it at the dealership(engine warm). Dealer reset the computer but it still does it.

Took it back to the dealer, he has had it for two days says it does not run rough or blow smoke. He still has the truck.

Any ideas on this??

should be a port on the fuel rail or general vicinity to hook a pressure gauge up to, another thing to do is get some gauges for your truck, fuel pressure, boost, egt, trans temp. so you can keep an eye on everything while driving, and since it's an rv puller, i would suggest getting them soon. or maybe the edge juice w/attitude since it has all the gauges on the in cab monitor.

does anyone make a gage package? I intend to get the Edge once my warranty is up. I was told it would void the warranty.

might want to check either the full pressure or the fuel filter. i had that problem on a cold engine start not cold weather but cold engine and i had white smoke and really rough running. changed the fuel filter has not done it since.

I prefer the quad monitor cause it does rail pressure also. The edge might but if you ever get tired of the edge chip it wont work with another chip/programmer as far as i know. And quadzilla chips arent traceable if you take them off. PM me if you are interested about it i dont mark them up much. As for the smoke.. could be an injector but most of the time an injector would do it constantly. It also depends on whether it was stuck open/closed. When i had an injector go out it didnt white smoke but it just dumped fuel into the oil. Check the oil level, and see if it smells like diesel or if it is thin. Also, if this is happening your oil pressure will drop so watch that too. Even after replacing the injectors mine had a small amount of visible smoke on startup in cold weather, but it quickly cleared. It could be the lift pump also. Dealer should be able to do a flow test on the lift pump for about fifty dollars. This is what they quoted me when i suspected mine was going out. Lift pump should sound like your running out of diesel if its bad. Some things you should try: I dont know how cold it is, but you might consider pluggin in your diesel cause the low sulfer gels bad. You could also try some fuel additive.. i use power services whenever i cant afford schaeffers. If it gets cold there, get additive that advertises anti-gel. Thats about all i can think of unless you can give some more symptoms.

not cold here, mid 60s at night mid 80s during the day. I had the dealer change the oil last week when I first took it in as it had almost 15k miles on the truck.

Definetly go with the juice with attitude. Very nice and lots of power and adjustments with all the gauges you will need to monitor. Yes you can piggy back on the juice with attitude I think. Atleast in the second gen stuff.

well, after nine days the dealer told me they replaced the trucks computer and it should be fine. However when I was leaving the service manager told me that it would Idle rough and blow smoke upon cold start for awhile. I told him that was why I brought it to him in the first place. he said I could have gotten some bad fuel. I told him this was the third tank full since it started blowing smoke and ideled rough on cold start.

Two days later I took it to another dealer, he told me that they had hooked up their machine and could find nothing wrong with the truck after two days. I went outside and started it and let it blow smoke into their shop as I left. I had even brought them a copy of the TSB on rough idle and blowing smoke on cold start. They said that was just a gudeline and they saw nothing wrong. Truck has 14,200 miles on it.

Any ideas on this?
