Car has been a bit hard to start when cold, so I hooked the fuel pressure gauge up tonight and when the ignition is turned on (but not the car), the fuel pressure only builds up to 10 PSI or so. Once the car is running the fuel pressure is normal, so I'm guessing its either the fuel pressure regulator or the fuel pump, most likely the fuel pump.

What fuel pumps are you guys using? Just a stock replacement from Autozone/O'Rielly/Advance/etc, or something like a BBK or Walbro? Even though my car is a 96 4.6, it uses the same fuel pump as the 86-95 5.0's, so whatever works for you 5.0 guys will be good for me.
