What type of information doyou need?

 

Did you check the link I posted? It says right there the info we need/like to see. Have you tried scanning it for codes? How many miles on it? Why were the initial repairs done? What oil and oil filter are you using? When's the last time fuel filters were changed, what's the fuel pressure???

 

Scanning for codes: The repair shop said they scanned for codes and it was reading alot of codes and they started deleting codes and now the truck runs fine and no more smoking. They said that the truck needs to be flashed??? The truck has 101800 miles. The initial repairs were done because the truck had a wrench light come on and the code that was pulled was oil cooler and EGR. Replaced. Then truck would not start. code read oil/fuel regulator changed. Now the no power and the large amount of white smoke from tail pipe.
Repair shop stated that it is a problem with the computer needing to be reflashed.

Dont know about fuel pressure or oil and filter?

 

I doubt it needs a reflash out of the blue, that doesn't make sense. Unless something else was changed and it's not cooperating with the PCM or ECM or FICM.

Do you have access to a scanner, or know someone that does. I'd sure like to know some of the codes they erased...
