OK so update,

I found the correct ecm for this truck from a bulletin the cat dealers put out, So I pulled a identical truck out of a good customers pulled their ecm same Nissan build number since that's the only way to tell which one is which put in this truck and the P03 P07 went away now I have e 38 Fuel Pressure switch and e30 Ecm power issue the only thing is install it back in the original truck no codes or I should say no e30 code I know the e-38 is in the fuels system of the other truck

Any hints on why the e30 code ?
