Autozone had the CPs for $29 I think it was.
Quite a difference in price between Autozone and O'Reillys.

Could be the engine control module (or engine control computer...same thing). If its not the cp try that. I'd start small though and work your way up. Check all fuses, electrical wiring, etc...

If replacing the CPS does not fix it, check the ground at the coil plug with a test light, it should flash while cranking. If not, then you have a cam sensor problem.

A bad O2 won't keep the engine from starting. Have you checked the fuses under the hood?
