Help, In the shop again

[welfordnremt]

I have lost top end power. When driving at hwy speeds I have no passing power. The RPM's go up but slow speed increase. The transmission seems to be shifting ok. Also, truck will not start when hot. Any suggestions of what I may be looking at?

Have you checked for any codes? P2262 or P2263 possible? I've read that the EBP sensor getting clogged with soot can affect boost too. Have you ever checked the voltage on the ficm?

I haven't been able to check anything. It happened on my way to the airport. I am out of the country. My wife has it at the dealership now. Just wondering what I might be in for.

if it is an 05 or newer I would say STC fitting...

It's a 03...

I have had about all I am going to take from this truck.. Going to have to get another one. I spent 5k on it last year.

since its a 2003 it probably does not utilize the ebp sensor due to the 06E17 recall. with the fact that it also wont start hot I would be suspecting a weak high pressure oil pump or high pressure oil leak, possibly an IPR. Higher mileage 03's are good for weak pumps ...Hp oil leaks are not too common but still can occur.

Thanks for the insight guys... Maybe I will know something tomorrow

According to the dealership, I need a new HPOP and Turbo,,,, What are the chances of both of these failing at the exact same time.

The HPOP sounds plausible for not wanting to start when engine is hot, but the Turbo is likely just dirty and can be cleaned by splitting the housing and cleaning the Variable Vanes and Unison Ring. Most likely you are not under warranty on an '03'. If you are under warranty and they are compelled to change the Turbo and it is covered, well have at it. I would asked them to specifically tell you what is wrong with the Turbo that it has to be changed, if it is not covered under warranty. Otherwise you can clean it yourself and save money. If you go up to the "repair" section for a 6.0L, someone has posted a link for removing and cleaning turbo. I did it and mine spools up extremely fast now.

It just really seems strange to me that they would both fail at the exact same time. I will have to fix both of these issues myself. There is no way I can afford to have them do it for 5k. This will be 10k that I have spent in the last 12mths repairing this truck. I will be looking at the repair sections for sure. Thanks for your help.
