Where is the fuel pressure read from? Before the rail? If you have 29psi before the rail you have to be basically using all the fuel that's getting to the rail, essentially running out of fuel and there's no fuel in the return line to get a proper reading. Just a guess, i have no idea how your system is set up just thinking out loud.
