eg6nes

Alright so here is the deal I just finished swapping a b20b in to my eg I was taking it down to the exhaust shop and on my way I noticed that it was running a little warm, but nothing to crazy so I just kept on driving I pull in the place and it dies so I try to start it back up and it only cranks. I have spark and fuel all fuses are good. The only code that I am throwing is O2. Please help me out.
