2011-2015 Duramax injector pump failure.

Yep they do something to the pump so it works with the stock system. Industrial Injection conversion to CP3.

There is a CP3 conversion?????? I wouldn't think so as the ECM expects certain PSI the CP3 can't deliver. Poor spray pattern on piston would almost certainly throw a CEL without a programing change.
I wouldn't worry to much OP. Keep fresh fuel and drain filter often.
The good side is GM has covered a portion of the repairs with truck out of warranty. I believe flyboy had this happen.

Yes failures are rare but they do hit the pocketbook ($10-12k) if your one of the unlucky ones.

That's my thought on it too. They don't blow often but when they do, watch out. It wasn't something I wanted to worry about as the years and miles wore on.

I'm not sure what a CP3 swap would entail but if it isn't too daunting it might provide some good piece of mind.

Lift pump, fuel additive for lube, watch where you fill and you "should" be OK. No silver bullet against failure unless you do the CP3 conversion though.

Bust a diesel engine, big big money. From what I have seen, never have a diesel outside of warranty no matter the make. Lots of them in my area, and the source of great income for the repair shops. Gas much cheaper to repair or replace compared to a diesel.

Has anyone on this forum had their Duramax tow vehicle injector pump to fail from normal use (no programmer on the engine). I bought a 2012 and I am concerned about the expense of letting it fail or going ahead and upgrading to CP3 before the CP4 dies.

yes, last year 2013 Silverado with Duramax. They called it a catastrophic failure; the truck came to an abrupt stop while traveling Nevada hwy. My DH managed to coast our truck & 5er to side of road. We were towed to Reno where cost of repair was 11,000. Fortunately the replacement was covered but left me feeling very vulnerable-wondering what would prevent it from happening again?
What made this more unnerving for me was we had just completed a 6 week trip and at one point traveled over Teton Pass. The thought of that failure happening then still leaves me feeling queasy.

oh and in before Ric blows this thread up

far cheaper to run a lift pump vs a cp3
