04 f150 xlt 5.4l triton 3v no start-need help

New parts-battery,starter, plugs, coil packs, intake manifold gaskets, fuel injector o rings, fuel pressure sensor, fuel pump module, throttle body with sensors

Codes-p0122,p0193,p0223,p2100,p2110

symptom-driving down road truck dies on me, got a jump noticed noise from under hood like a blown plug. Drove it almost home and before it died it made a loud backfire pop. Towed it home and that’s when I started replacing the parts.
I am at lost I’ve tested the electrical connectors to the throttle body for 5v and they all tested good. Could this be a fuel pump/filter issue?
truck has 217k miles on it and I know the catalytic converter is clogged and needs replaced. Any and all advice or help is greatly Appreciated thanks in advance.

Those are all throttle-related codes. However, a clogged cat can cause so much backpressure that it won't run and cause backfires.
