Did you change your tire size with the MM3?

Shot in the dark, because you mention several things, but have you checked your lift pump?

Do you hear the pump priming?

I had something like that happen to me over the summer, truck left me stranded at a gas station I stopped for coffee.

Cranked a couple of times and then nothing and had to have AAA tow it.

Mine did show a generic fuel pressure code though, IDK if you checked all codes.

Hope you get it resolved soon.
