Well I have a 05 cummins with (CAI and 4" w/cat delete). Started it up Sunday and the idle was choppy and white smoke was coming out of tailpipe. No prior symptoms, I did get diesel the night before so I thought maybe water in diesel? I changed fuel filter and added seafoam and it cleared up. Today it started happening again, changed fuel filter again. Still doing it! Could it be water? And should I just scrap the fuel or is it something serious? Any help is greatly appreciated

 

sounds like bad fuel....I have done up to 5 filters on a deal like this before

if a load of diesel is being dropped dont fuel up, dropping the fuel stirs up all the crap on the bottom of the tank

 

Change your fuel station for diesel see what happens. The winter blend is sometimes

 

Thank you guys so much

Also I'm getting some more than normal vibration from the motor at 60mph and over? it could be unrelated but i forgot to share earlier, sorry.

Ok now the damn thing won't start! I'm getting fuel from the lift pump, I'm getting fuel to my injectors. But it's cranking like a Gasser that is not getting fire! I'm at a loss? I've heard of a sensor that's on the rail, could it be that?

 

on my 07 it would start up and was choppy and had white smoke and was a little slugish on power to so i checked im air filter and it was wet replaced it and havent had any problems

 

Not to scare you but could possibly be a Injector issue! Those are common symtoms.

 

Ok, I cleaned my filter and it still ain't starting. I appreciate the comment but it doesn't seem to be the problem.

Also I dropped it off at the shop today, so we'll see.

 

Well today the mechanic got the truck started by putting seafoam in the fuel filter can. After it started though it was idling erratically, but would stay running. Whereas before it wouldn't start at all? Any ideas are greatly appreciated.

 

any codes?
