1999 Daewoo Nubira No spark

I pulled the codes off the OBD port and got codes for crank sensor and also cam sensor. I did a ohm test on bolth the cam and crank sensor and they are between 200 and 500 ohms. I tuned the ignition on and read voltage on the plug on the cam which read 12volts. The crank only read 1.35 volts which is nothing in my mind. I did a continuity check on my wires going from the ECM to the plug to the sensor and it was good. I checked voltage at the ECM and got the same voltage readings I got at the plug. I have narowed it down to three things. My cam sensor, my crank sensor, or my ECM. But I did pull codes off the ECM. Any advice as what nexed?
