Driving home today the SES light came on. Both the P0216 and P0251 came on at the same time. Engine seems to run fine, has 55K miles on her. I have bought this truck in the last week and Plan to change the fuel filter, do you guy think the FSD or IP is heading south?
**Updated**
I replace the fuel filter. When attempting to purge the air fuel never flowed from the bleeder. I checked the lift pump on the frame rail, it is getting power but has no continunity and I can't hear it run. I should be able to hear this correct? Being a motor is should have some continunity also correct?
**Updated** Thanks guys, it was the lift pump. Everything is fine now and no codes.
