Used ones are normally knackered boss.

Get a Bosch one, get it fitted, clean the throttle pot and it'll be right

The ecu doesn't read lambda when you've got your foot hard in the sharpie, it reads throttle position at 100% and fuels accordingly.

Pretty much this

Also, that whole thing about sucking crap through is a myth just FYI. The pump takes the fuel from the bottom of the tank regardless of how much fuel is in there.
