Fuel pressure should be 55-62psi at idle, was the fuel filter plugged?If you have black particles could be possible fuel contamination. Fuel pressure is still to low at idle. Also with the fuel guage on it, turn the key on let the fuel pressure build, then shut the key off and see how long it takes for the pressure to drop, shouldnt drop any more than 5psi every 20 minutes. If it dops fast could have an injector leaking, but I would go after the fuel pump.
