99 2.2L won't start

[chevy_20]

I can't get it to start. It will turn over fine. I've checked everything I can think of but still can't figure it out. I'm getting good spark and fuel. I've sprayed starting fluid in the intake and it still won't do anything but turn over. Someone told me it may be the cam sensor? Will a bad cam sensor cause this? Where is the cam sensor located? Any other ideas? Thanks
