hey guys, I am a new one here so bare with me

I just picked up a very nice 58,000 mile 96 with the duratec in it.
Well, she will crank and crank, but not start.Battery is low, but I had a jump box as well as charged it up and jumped it off of a running car with jumper cables.
I verified spark, and fuel (not pressure) , as well as tried with starting fluid.
I guess my questions are ;
I have heard about how important a good battery is on these cars. Will it really not start even though you have enough juice to crank it for a long time, over and over?
I am not sure if it has PATS. I know the key that came with the car does not have a chip. Is there any way to verify if it does or not?
If it does have PATS, will it still allow it to crank , but not start? Or does the starter stay dead also with PATS?
I will know more tommarrow as I only had about half an hour with it today.
