Well away i go ; Did not run out of gas but had a low tank and parked on a sideways hill; Went to start it next morning and no luck; So put gas in and then it ran; The wiring under the car by exhaust o2 looks a little damaged and i will try that. The heater o2 sensor is it located on the top of the engine block towards the frount? goes into some box looking thing with hoses that come from it looks like from the waterpump?

Thanks for helping me; Its about 32 outside and i'll check that stuff you said above.
