Went to start my truck this morning after it had been sitting for 12 hours. IT got down to at least 32 here last night. It started did the romp romp and and smoke came out kinda blueish white and it idled rough. I let it warm up for about a minute and till egts got to 400. I backed up it was running rough i was trying to get to the gas station because my low fuel light had been on for about twenty miles started to lose power and still running rough so i pulled over shut it off. I went put fuel in it started it would crank start idle rough for about 5 seconds and die and rpms would not go up.finally got it started it still idles rough but will run and not die and still runs rough. My freind had a similar problem and pulled the sensor that goes to the valve cover to the right of the fuel filter if your looking at the truck and it ran fine. I tried this it idles fine but still runs rough when you try to go. I did this for less then a minute.

. Do you think it just got to low on fuel?

 

all kinds of codes there..most of them are from the chip... if its air from running to low on fuel..it should straiten out after25 to 50 miles or so....thats about what it sound like too..you may want to open the water valve on the back of the fuel bowl just incase you got water from the bottom of the tank..

 

Low fuel will cause the rough running and cutting out. It will take a while to get the air out if you sucked any in. Are all those codes common with your truck? The 1211 is the one that could also point towards the problems you are having.

 

ok hmm would idling get the air out?????????????? Yea that code is as recent as a month.

 

Yes, the air will come out when enough fuel has passed through, The 1211 points to the HPOP system and should be of some concern. Clear it and if it comes back, I would think that may be part or all of you rough running problem. Could be a bad IPR, ICP, or other thing that affect your running.

 

that is possible..but the DP will throw a 1211 too..if you clear it..drive like an old lady and see if the code comes back....

 

I second the fuel / water drain. I hate to admit it, but I ran mine nearly out (it actually quit at one point) about a month ago. It ran a little rough for about ten miles at 55 mph then seemed to smooth out (or as smooth as a diesel gets). hope this is your only problem.

 

32 degrees + low on fuel= could mean that water and condensation may have froze in the fuel lines and or in the fuel bowl. Running that low on fuel in winter temps is risky in a diesel. You also run the risk of picking up dirt from the bottom of the tank. Makes it harder to diagnose if you add these variables. Fill it up, work the air out of the system clear all codes, drive like a grandma, pull new codes too see if you have them.

Also, a must for PSD's that have some miles on them is cleaning and or replacing (easier) the EBPV tube and sensor too keep you rig running like new. May even clear up your P0475.

 

It sounds like your friend unplugged the ICP sensor. This will cause the PCM to assume default settings and will work at idle but not driving. Have you tried removing the ICP to have a look at it?

 

Chris, look over his post, I think he is talking about his truck and referring to his friends truck.

 

Maybe your right, but the way I read it said he tried unplugging it and it idled fine but would run rough. With it plugged in it idled rough.

It doens't look like he's online now, so I guess we will just have to wait.

My bad, you're right, that is what he said. Duh!

 

Yea I removed the sensor. It idled fine but still didnt drive smooth.

I have deleted the ebpv with the new turbo thats why im getting that code.

 

Did it have an oily redidue on it? It sounds like you may need a new ICP sensor.

 

I had some quetions about the ICP sensor . . . my truck cuts out randomly while driving and i replaced the CPS and problem still exists, ive heard alot of people pointing to the ICP or IPR sensor. I dont know alot about either sensor any suggestions or information woulod be appreciated.
