99 corolla turns over lazy, does not start

I have a 99 corolla that recently decided it
won't start. I had taken the car out on a
drive with my GF, parked it to get some
snacks, and when I tried to start it, it would
turn over lazily but not start.
Couple things I've tried, oil is all good,
battery is good, plenty of coolant, tried
spreading some ether in it, no go on that.
Hooked up the diagnostic computer to it,
only fault I got was for the catalytic
converter. There is also smoke coming
from the exhaust so I assume it's getting
fuel. The car does turn over it just dosent
catch and fire up.
