Default Code 45

I thought I had my rough idle\stalling problem solved...thought it was a faulty IAC...but the problem still exists. I pulled a code 45, which is rich exhaust. One of the things the manual says to check is fuel pressure. I have zero fuel pressure?? How is that possible? My car fires right up!! Can that happen with no fuel pressure. And wouldn't I be running lean if my fuel pressure was too low? My fuel pressure gauge is almost new...by the way, so is my O2 sensor and my fuel filter. I don't get it. :confused:

Check fuel pressure regulator, bad EGR valve, or maybe a leaking injector. Check charcoal evaporative canister for smell of fuel. 84 CF 91 ZR-1
