Injection Pump failure is a much too common problem on the 2011-2016 GM LML Duramax Diesel, if your CP4 injection pump has failed and you need to replace your pump, injectors and fuel rails, then here is a kit put together by DmaxStore to completely replace the GM CP4 Injection Pump (12661059), GM OEM Injectors, and the GM Fuel Rails (12620532 & 12651989).  DmaxStore recommends to replace your entire fuel system if a CP4 injection pump failure occurs, as it is vital to have a contaminant free fuel system to get the maximum performance and reliability.  With the new version of the CP4 injection pump Bosch has updated it with the newest parts and components to help prevent future failure. Add our LML Injection Pump Complete Install Kit and you will have all the necessary parts, gaskets, and seals to perform this repair.

DmaxStore Note: After install, you will need to perform the LML Injector Correction Reset. Once completed, Injector specific Flow Rates must be programmed into glow plug control module (gpcm) and engine control module (ecm) for specific cylinder locations.
