have a 97 catera, has signs of leaking oil cooler or cracked head gasket. It will turn over but wont fire up and start running. Its got oil, getting fuel, and has a spark from plugs, all fuses are good. Could something electrical have gone bad, or the timing has jumped? Or did something internaly break in the motor?
I would have to look to be sure and I don't have ready access at the moment but to best of my recollection it's referred to as Camshaft Position Sensor, CPS, in the factory service manual and the parts stores use that terminology for the correct part for this car.
