Now I'm confused. In your first post, you said it starts, but now it doesn't. When did it become a no-start condition? Before this goes any further, let's cut the possibilities down.

1) Disconnect the battery for 15 minutes and then retest KOEO. What codes are present?

2) I need for you to verify whether or not fuel is being injected when you are trying to start it. Do this for me by trying to start it for 10 seconds, and then removing a spark plug. Is the plug wet or dry?

3) Disconnect the TPS. With KOEO, measure the voltage between the orange wire and the black wire at the harness side of the connector. What's the voltage?

4) Key off, reconnect the TPS. Backprobe the green and black wires. With KOEO, what's the voltage with the throttle closed? at WOT?

Answer the no-start question, do those 4 things, and post the results, and we'll go from there. Otherwise, we're just chasing our tails.

Take care,
