quit buying parts

if the check engine light is on then the computer is storing a trouble code
this trouble code will TELL YOU what sensor is responsible for the fault code and many times why

Buying parts is a waste of time and $$$, the fuel pressure regulator on a 92 has NOTHING to do with the check engine light, unless of course the 02 sensors are picking up a lean or rich condition because of fuel pressure issues

pull the code

410fortune.... I think he indicated that the code was 173 and that it appeared AFTER he changed an O2 sensor. If it indeed is the code and is rich, his "guess" that maybe the FPR is not "functioning" correctly, then maybe its a good bet. The other thing that he might try is a fuel pressure test over a 10 minute period to see what pressure readings he is getting to help confirm his "guess".
