92 olds ,3.3 obd 1 ,codes not matching no start condition?

I suspect the cps or crank sensor as I have fuel pressure , no spark , just trying to avoid hanging parts until I feel better about what part to change ! three codes say 02 sensors , so thats not the problem , one code was 48 , and the description still didn't help , unless it is icp related . . . any ideals ?
