2013 lost rail psi

[tanman_2006]

My 2013 lml with deleted, fass, and motor ops tune shut off going down the highway.

When cranking it has 0frp. The desired frp shows 5.2k.

Shop is thinking cp4 quit. Thoughts? Time to cp3 swap?

 

[THEFERMANATOR]

Dead cp4 would be my guess. They tend to just die without warning. Bad news is they normally fill the rails and injectors full of metal when the go. Make sure the rails are cleaned and all lines are flushed.

 

[tanman_2006]

Yay.... more good news....

So should I just plan on lines and injectors now or just see how it goes?

Who do you recommend for a cp3 and injectors these days? Alligator is currently selling kits from industrial injection and HS Motorsports.

Looking at maybe a hair over stock, nothing extreme.

How many miles on motor Tanner?
Sorry to hear about these issues

 

[tanman_2006]

Just under 174k

 

[RI Chevy Silveradoman]

Crap. Hopefully the new fuel pump does it for you and your back on the road for another 175K! lol

 

[tanman_2006]

I have metal shavings down to the rails. The shop suspects the injectors ate metal too.

This is sounding expensive!

Wow Tanner!... This is NOT going to be easy on the wallet.

 

[tanman_2006]

We are up to 10k including labor at the moment

That sux!

I can add this to another reason I am glad I got rid of my 2015.

I was going to say $10K seems to be the going rate for a grenaded cp4. They fail without warning, and for no reason. It's part of the reason GM cut ties with Bosch.

I think VW had issues with CP 4 too!

 

[tanman_2006]

Exergy Sportsman CP3, industrial 20% injectors, wherli intake, lb7 up pipe, stainless downpipe, and upgraded tunes going in.

$7500 in parts

This sounds like my LBZ. When the CP3 let loose, it took out some injectors too. I did it all -- it was over $7k (I did the injectors and hard lines myself and installed the FASS so saved on some labor there). Local shop did the cp3 and egr cooler.

Whatever way you go, hope it treats you well. I've gone about 45k miles since it all happened. I did loose one injector exactly a year after install but no issues since. --knock on wood--

What was the mileage on your truck when tge CP3 crapped out Big Dog?

93k. Way too young. I assume the PO had no clue what a fuel filter was.

 

[RI Chevy Silveradoman]

Yikes. OK Thanks Big Dog.

 

[tanman_2006]

It's still in the shop. Hopefully I get the lead sled out of the shop next week
