Fuel Pump Problems

[t mark]

I have a 2005 - 6.0 PowerStroke. Yesterday, I did the upgrade on the fuel regulator on the blue spring. After I finished, the truck started and then it ran 30 seconds and died. I have no fuel pressure at all. I know I have a 1/2 tank of fuel. As far as I can tell, the pump is working. Has anyone else ran into this problem? Would appreciate any feedback I can get. Getting very frustrated. Thanks - t mark

have you tried cycling the key back and forth a few times and each time just let it sit for awhile you should hear your pump run for awhile it is noticable whent he pump is running if you cant hear it probably quit, by any chance did you change filters to?
