injector codes 2015 Pete 579

[watkinstt]

With Cummins codes 1139, 1142, 1144, 1143, and 1141. This truck originally came in because it was putting coolant in the fuel. After diagnosing we found the injector cups were leaking. We purchased and installed an aftermarket cup kit. This corrected are coolant in fuel issues but we have been getting these codes since installing. These codes were not present prior to installation. We have checked fuel restriction per Insite and see no issues there. We also removed and replaced the fuel supply tubes to each injector since we could not confirm they were put back with their original injectors when cup kit was installed. Any information or ideas would be appreciated. Thanks in advance.
