I'm getting a P0445 code.

checked the fuses, tried unplugging the battery,

Is it ECM related, Or do I just replace it? What do I do to replace it? Thanks, Ken.

Cranks, but won't turn over. I primed the fuel filter, there's fuel there. What else should I check?
The engine light is not on. I loaned out my code reader, haven't got it back yet.

My truck at 37,500 miles the Change fuel filter indicator light came on. I had the fuel filter changed & the light came on again. I took the truck back to the shop & they reset it again but the light keeps showing. The shop used the computer thingy but I was told the computer says its not communicating? What is going on? is it common & maybe a problem that will be covered under a recall & if not how much will it cost to fix? thank you so much in advance.
