Duramax

[Toad]

I’m new to this site but curious! I have a 2016 Chevy Duramax 74000 miles cp4 pump failure! How the hell do people afford to fix this disaster? Of what can be done

Basically you'll have to replace the entire fuel system because of all the metal contamination throughout it. Last I heard it was around 6-8 k. You'll need a CP3 conversion to go along with it. I put almost 7k in my 2013 to solve the problem ahead of time and added a 'few' other related trinkets from WCFAB.
Sorry I don't have better news.

Welcome. I feel for you all thus the reason I unloaded my Ram a while back due to $5K plus repairs every time. Back to a gasser I went.

There have been many, many trucks “stolen”, and stolen. Some guys still one for the parts, get theirs running then sell it to get away from the issue. Other guys park it in a garage where it gets stripped apart, then a few months later call the cops to report it stolen.

Around Vegas that price is low. 10-11 grand.

Does a lift pump help to eliminate the problem with the CP4 pump ?
My son has a 2016 Diramax and I mentioned to Him about a possible pump problem and He just shrugged it offt.

Am I correct in assuming that my 2006 Chevy, LBZ Duramax has the CP3 from the factory, no mods ever made, so it's stock.

A lift pump may delay the inevitable problem. Lack of lubricity in ULSD in America is mainly the culprit. A CP3 conversion is NOT cheap, but it's a lot cheaper...

Yes, you have a CP3.

I texted this statement to My son that has a 2016 Duramax. I warned him in the past about it but it was to no avail. I hope He takes notice before the failure happens to His truck.

I got to ride in the sons Truck when I was in Alaska last summer. That is a mighty fine unit and I know if I had one of those that I would uprate any components that might extend its life cycle.
