my 6.4 has about 220,000 miles and yesterday both sensors errored out.. So I replaced them both … Started fine the first time.. after sitting all night I went out in the morning and it would not start... I have a mini maxx on it cuz I deleted the DPF and EGR so I deleted the codes and it started fine... after work the same thing... didn't start clear codes and fires right up and runs fine..

any suggestions?
