90 Blazer

Won't start unless primed (throttle body), found oxygen sensor hanging down (poped out) I know it's probaly the pump in the tank, vehicle set for years and probaly filter all varnished and soaked with gook. But my question will it run without a oxygen sensor?

not real well

It might run but not real well as it is part of a loop that sends the correct amount of fuel to the TBI. Also it will never pass any emmsions inspection here in the USA.
