2018 Ram 1500. I have owned this truck about 8 months till the check engine light came on. Took it to the dealer and they found code P026C. I had it repaired at said dealer for $800.00 out of pocket. They replaced a sensor, replaced a fuel filter that was only 2 weeks old and a few other things I can't remember right now. Any ways it's one week later and the light is back on with the same code. Does anyone have a fix for this problem? I have read some posts but cannot find an answer. I really don't want to shell out another $800.00 on a wild guess.

I own a 2016 1500 ecodiesel- I have the same code showing, this is due to the federal recall on 130,000 Ram and Jeeps with the ecodiesel engines, high-pressure fuel pump failure. The pumps are self-destructioning and restricting fuel lines and injectors with metal fragments. There are no replacement HP pumps yet, they say maybe next year! Look for recall notice.

Thanks ever so much. It makes sense from what info I have so far.

Well you are on the right path. the DTC P026C is stated as Fuel Injector quantity lower than expected. Basically not enough diesel fuel flowing through the injector. Yes this can be related to the HPFP not supplying sufficient pressure, which could also set a Low Fuel Rail Pressure code. A quick fix would be replacement of the fuel filter, which appears did not fix the issue. My truck is loosing the fuel pump assembly, in the tank, which supplies the HPFP and it has set that code as well. There is a flow test for the fuel pump to determine if it may be the issue.
There is a recall for the HPFP, we got ours a month ago, and there is not sufficient inventory to replace all the recalled units. Our local dealer has informed us that if you truck is down it becomes a priority and will be repaired within a two week period, (may be a situation with our dealer only) otherwise expect parts in the 2nd quarter of next year.

Good luck.
