CYP Sensor

Wondering if someone can help me out. I have a 91 gs and it wont crank. Thought it was the main relay, replaced it, still nothing. I checked the ECU and gave me a code 9. Here's the thing. From what I'm seeing, the CYP sensor is in the distributor. Couple of months ago, I had gotten a new igniter unit, coil and rotor, all cost me around 200. Would it be better to replace the entire distributor and spend another 200, or just the CYP sensor (if i can find one)? Oh, and so far, over the year, i've replace the alternator, battery, cat. conv., muffler, o2sensor, clutch, and the distributor parts.

can you purchase the cyp seperate??

thats what im trying to figure out. i've looked online for them, and cant find one.
