2011-2015 Duramax injector pump failure.

I think you'll learn why you didn't switch earlier

Well I hope for their sake they don't change over to the CP4. I guess I will find out if swapping brands was a bad idea if this D-max pump lays down.

Don't worry soon the Ram owners will be here to tell you how bad they are...But I can tell you my previous 2011 ford racked 100k miles with zero pump issues.

Word on the street is the CP4 can grenade at anytime. Problem is, no one knows what the percentages are since we don't have access to that type of information. All we get are forum posts of a CP4 going. Who know, for every one that goes, there could be 10,000 (+- 9,999) that don't.

Injector failures are largely unheard of in newer trucks. Filter changes is cruitial for clean fuel.
