Fuel Pressure Regulator

Regulator is mounted on end of fuel rail closest to distributor. If fuel pressure is not within specification, check fuel pump unregulated pressure. If unregulated pressure is within specification, check for clogged vacuum passage between intake manifold and fuel pressure regulator. If passage is clear, replace regulator.
