No Pressure at Fuel Rail-Fuel Pump Works (or does it)

A lot doesn't make sense with this and I get a feeling there is more to the story. Can you get fuel pressure (not just flow at zero pressure) at the pump? What happened leading into this ? Maybe make sure the pump is getting a full 12volts while you have access to it.

Thanks for the help and guidance.

The vehicle ran perfectly. 5 minutes into a drive the other morning it lost all power, sputtered and would not drive. The engine still starts right up but idle is rough. Applying gas pedal bogs down the engine and it dies.

With my test hose connected to the pump, I get good flow. I have not figured out a way to measure psi on my test hose. I will see if I can rig something up. You may be on to something....I have flow but not pressure causing me to "think" pump is good.

I was going to pull the fuel filter this evening and see if I can determine flow into the filter and out of the filter. I don't know if a clogged filter could reduce pressure down to zero though.
