You can get O2 sensor codes with a bad pump because he engine is running lean. Especially on an older vehicle!
Yep. Those senors can really get out of range out under a lean condition and throw all kinds of codes. Ensure proper fuel delivery before replacing anything else.
In one post the OP said the 'tank was recently cleaned out'. Just because a tank is cleaned it doesn't mean there is nothing left to dislodge. In fact, it can be quite the opposite and the cleaning can loosen a bunch of junk that starts flaking off. The problem very well could be a plugged pre-filter on the fuel pump or the inline fuel filter.
I too would place my bets on some kind of fuel delivery issue.
