92 Pathfinder fuel injection problem

HI there. I have a 92 Pathfinder that just quit running the other day. I am getting fuel to the fuel rail, and I have plenty of spark and compression, but the fuel is not getting into the cylinders. I crank it over and pull the plugs and they are dry. I have replaced the ECU and that did nothing. The ECU is sending a code of 55 which is "No Malfunction". Is there a relay or fuse somewhere for the fuel injectors ?? I can't imagine that all of my six injectors died at the same time. I have inspected all of the wiring between the ECU and fuel injectors and everything seems to be fine. Any help would be greatly appreciated. Thanks in advance.

Sounds like fuel pressure. I don't know the specific requirements for Nissan ( I own one, but mostly I'm GM) I do know port injectors require 50 psi or so on gms, as opposed to 12 psi on Throttle body injectors, and 2 or 3 psi on carbs. Start with a new fuel filter, then get a pressure check. Good Luck and have a merry merry George
