Cold/warm or does it matter to you?I've checked the harness's before but when I get time I'll do it again.

 

I was allways told that blue smoke means bad injectors, just my opinion, hope it helps

 

Blue smoke can mean injectors, injector O rings, turbo, Turbo O rings, Valves, valve guides... Lots of things...

 

Pull the PCM and have a dealer or credible tuner reflash it.

Chock it up to an expensive lesson about the consequences of running inferior tuning.

Once we know that you do in fact have the proper programming in that PCM, the numbers will mean something to us.

Until then, they could just be the product of a corrupt file in the PCM.

 

Ok,pull the download out first obviously,reflash and start from ground zero?Will try an arrange the reflash this week if poss. Thanks

 

Don't ever use the pred again. Ever .

So, since you're never using it again, it doesn't matter what's on the PCM when you have it reflashed.

But, I think you definately need to make sure the PCM is tellin the truck the right things, before you can trouble shoot the truck.

 

OK..OKtook the truck and had the pcm reflashed and it runs like the poop!No power!DID not put the pred back in!

drove approx 12 miles home and had a code 0603
key on eng run self test came back with a 0476-again without the tuner this thing is a turd,cyl contribution test shows #7,inj buzz shows no codes but can here inj buing.

 

603 is KAM. Keep Alive Memory. No biggy, the PCM's probably just realizes something is different than before.

P0476 exhaust pressure control valve ckt range/ performance. I'd ignore that one too, unless you're gettin the rushing noise that indicates the EBPV is actually closed. If so, disconnect the two pin plug on the pedistal and you'll probably fix the problem.

 

Will that cause a hard start no start condition cold?

 

No, it'd cause a no power condition though.
