I swapped my engine out and ended up driving it around for about a month. And then I refilled my coolant and was in the process of bleeding it and then it started idling funky and once I shut it off it won't turn back on. I believe it's a fuel problem because I cannot hear my fuel pump priming or running when turning the ignition on or cranking the engine over. I did the five stomp method and it's giving me the code: (1222 - Oxygen (Lambda) Sensor Control 1) so I swapped my O2 sensor out and it is still popping up with that code and not starting.

Hmm, I would try starting fluid to see if that makes a difference. The oxygen sensor will not make it not start. Could it be that you have old fuel in the car and it has gummed up the fuel pump?

Here is a video to go over to help us see what's going on:

It will show you how to check for the fuel pump or spark related issues. Please go over this guide and get back to us.
