If your saying it cranks good, but won't start. Did you ever chek fuel pressure?

What was the fuel pressure reading? Those spider systems are noted for problems.
KOEO fuel pressure should be 58 psi or above, or it may not start.

If you retrieved trouble codes, what were they? The codes won't tell you what to replace, just that there is a possible problem on that system.
Did you check for spark at the plugs, with the engine cranking? Are you saying the engine ran ok before you worked on it?
Your fuel pressure looks ok. Did you try spraying starter fluid past the throttle-valve? Does the engine try to start? There can be safety issues using a flammable spray, that is your responsibility.

The code 23 has to do with the inlet air temp sensor. You can do a resistance test on that sensor, see if the resistance changes at different temps.
The code 45 is o2 sensor rich, I'd look at the iat sensor and circuit, first.
