Multiple trouble codes

My 2007 4.7L Tundra has 70k miles. Everything is OEM with the exception of the SAIS bypass kit from Hewitt (which I originally installed 11 years ago). I've had the truck for 12 years and had very few issues with it. It's not my daily driver though.

Seemingly out of the blue, I got CEL of P0113, P0102. I replaced the MAF sensor and got no change. Spoke with Paul Hewitt and he suggested replacing the SAIS bypass kit (which I did). No change. I believe it's unrelated to the mod. So here's what I currently have:

P0113, P0102, and now C342D on start up. It will start but most of the time dies right after unless I press the accelerator during starting.

If I drive it (it's in limp mode), I get codes P0055, P0037, P0057, C342D, C3064 (the previous/original MAF codes disappear).

The VCF and 4LO is flashing, CEL and Traction Control on solid.


Any ideas? I'm no mechanic by trade, for sure but I don't mind to get my hands dirty and watch a video to do my own repairs. I'd like the figure this thing out (even if I have to pay someone to do the repair). My next step at this point if to start looking for rodent damage, as these codes appear to be unrelated.

Thanks in advance for any ideas.

UPDATE: Blown fuse, 10A EFI No.2 Fuse. Fixed all issues.
