You say it is cold where you are,you could have a frozen fuel line. Since the car had been sitting a while,you could have had some water in your gas line that is now frozen. I believe at the end of your fuel rail on the engine there is a schrader valve(looks like a tire valve) Just push it in and see if fuel squirts out. If it doesn't then your fuel isn't reaching the engine.

Okay so fuel pump is good, spark plugs good, fuses good, pressure in fuel lines good, battery goo.... the only thing i saw that looked bad was the o2 sensor, could this be the problem? I haven't check the cam position sensor but that's next on the list, how would you know if that is bad?

I don't think a bad O2 sensor will prevent it form starting just from running well. Those sensors are expensive I wouldn't just replace it, try cleaning them first. My cam sensor was gummed up with oil from a leaky seal. I used CRC electronics cleaner available at Autozone/Advance.

I think the cam position sensor is aka the crankshaft position sensor, correct? People have thrown out two names but I think they are one in the same.

Cam sensor
Crank sensor
Two different sensors. Just as the names imply, Cam sensor onthe back end of the exhaust cam, the crank sensor in the top of the bell housing.
Now I'm going to go back and read the whole thread.

Dude, if you are saying the car cranks but doesn't turn over...this repair is over your head, better take it in.

The bell housing is where either the clutch or the torque converter lives, just behind the engine but before the actual transmission. I guess it gets its name since it is kinda bell shaped.
