o2 sensor question

[clutch1]

O2 sensor won't make the car not start... doesn't even start reading until a minute or so after the engine actually starts (has to sufficiently heat up).
That being said, downstream (after cat, yes?) is even less of a player, simply monitoring if the cat is doing it's job.

You say it takes 30 mins to an hour to start? Explain.. you just crank it for a half hour, whaaat?

I try and start the car but cranks over. i turn the back to off and try and start,but nothing. i do this for like i said 30 min. to an hour and out of the blue it starts. once i turn the car off its back to the same procedure to start the car.
