Doesn't matter about the O2 just yet, the computer doesn't look at it until the engine reaches operating temp. But you definitely should not have any raw gas coming out of the exhaust, put a pressure gauge on the fuel rail, if pressure bleeds off immediately after the engine is shut off one or more injectors are stuck open, and that can be caused by an electrical problem(pinched or rodent chewed wires) or because of dirt or deposits in the injectors.

I got 8 used injectors last night. I cleaned up the two best ones and tested them on the harness and they worked (I could feel them in my hand ). I checked fuel pressure and I had non. I think it was leaving threw the injectors before it could build up.
I just put the new injectors in. I'm going to check for pressure next. I also noticed that my crank case was full of gas ....... To be continued
