i hope i am not beating a dead horse with his question , cause i have hit the search button to try to solve my problem .. but it is a little different then a few other ..
o.k . it is getting a little colder here at night .. but not that cold were there is frost or anything ... anyway my problem is when i go out to start my truck in the morning , or if my truck has sit for a few days and not been run .. it start right away and idles really rough puking white smoke for about 4-5 seconds and then clears right up and runs like a top .. and once warm ed up it start perfect ???

any ideas ????

I would run some injector cleaner stat, your symptoms lead to bad injector(s)

have you changed you fuel filter lately?

 

also take it to the dealer and have your ECM updated to the latest software available for your truck.

a few months ago i usually change it every other oil change .. i do my oil changes every 4000 miles

 

i would go ahead and do it again to rule that out.

 

i had the white smole tsb done a couple yrs ago

 

have you checked for codes?

 

no .. what is the procedure for that again ?? 4 key cycles ???

pulled the codes this is what came up

P0191 –

i looked it up and this is what it says

Fuel Rail Pressure Sensor Circuit Range/Performance

 

hmm hopefully someone will chime in here who has had experience with that code and can tell you what to do.

 

o.k. so i went out tonight and tried to start my truck .. and man !! it was a bugger to start !! after about 4 tries it did start and idled terrible for a bit and then finally cleared up !! you know the funny thing is i never did get a CEL come on ever.. and up to this point i have never thrown a CEL or a code !! argh !!!
any suggestions ??!!!

the rail pressure code your getting is pretty common if you're running a box that increases fuel rail pressure. i had it myself but was able to clear it after several attempts and it has not come back. the starting problem you are experiencing sounds exactly like the one that i had until i got a re-flash about 3 weeks ago and have'nt had the problem since. i don't think this version of the new software has been available that long so if you were re-flashed several years ago it might no longer be the latest version for your truck.
