GPCM = Glow Plug Control Module

Ok,

So you do have custom tunes. I think the first thing that needs to be done is to fix those glow plug issues. I can start my truck unplugged on overnights like we have had the past few days. I just cycle the glow plugs twice and have no issues. I never run my truck for 15 minuites every 2 hours. I never had any fear of the truck not starting.

just replaced my passenger battery and now it will start fine old battery was putting out 436 CCA new one will put out 880 CCA so starts alot better still have glow plug issues

 

Hows the other battery, I would replace them in pairs. Just my .02 though.

ya thats my plan money wise i can only replace the one, couldnt get back and forth to work so replaced one for now then i will replace the other one when i get the money so like next week or too but the drivers side was putting out 736 CCA

 

ok yes 6.0l have a gpcm and not a gpr so i just connected my lack connector on the gpcm and my codes are gone. so all fixed. ya the SF3 receives downloads from SCT and i can run those want to see whats different between a X3 and a SF3

 

I cant help you with the differences, maybe go to the website and see. I think its SCTFlash.com

Hey gang, I have a fairly stock 2006, and I have no coolant loss, do not plug it in at all, in fact I have never plugged it in, I change my fuel filters every 3000-4000 miles just because of the work I do, but here recently I have been noticing the same, White smoke like crazy until you get her all warmed up and then it just quits? Am I assuming correct that if it were a Head issue that the smoke would not just go away? What would make the EGR system blow white smoke? I am in the northern WV southern PA area, so its cold but not NY cold. I would like to get it figured out though before I roll over my warranty mileage. Any and all help is appreciated!

 

 

I would say if you have no coolant loss then it probably is not egr or head gaskets. That's if you have NO cooant loss. I would plug it in and see if that made a difference as well as see if the latest flash would help. Does it smell like fuel or coolant? Maybe just emission in the cold. Hard to say, how cold is it? See if there is any codes thrown. Usually with HD failure you would be blowing coolant out of the degas bottle and if it was an egr cooler failure your coolant level would lose some over time.

 

I Had this problem.. It was the FICM. A pile of white smoke till engine warmed up and then clear. It was covered under the emissions warranty (5/100,000) with NO deductible

 

Could check the voltage out of your ficm and see if that is the problem. Anything under 45 v, needs attention.

 

Well what was it??

 

I think he said it was his ficm.

 

FICM?? fuel injection control module?? where is that located to check the voltage? Should I just take it to a dealer and let them have a look at it?

 

If it is under warranty then yes, let the dealer "deal" with it. If it isn't then we can help you out with the location and directions on how to do it. Just let us know.
