I replaced the coil on the number 8 cylinder. A day later I am getting the P0461 code. I just replaced the fuel pump lest than 6 months ago. Could there be something else causing this besides the fuel level sensor?

 

Anything fuel related, it is always a good idea to check out your fuel pump driver module. (FPDM)

 

I replaced that too about 6 months ago when I replaced the fuel pump.
