Question Fuel Pump Problems

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

A better title for your post might be “Fuel Pressure Regulator Problems” I would try to find some pic’s of how it’s assembled and make sure you got it all back together correctly. Worst case install the stock parts and see if that helps. Maybe post Pic’s and see if anyone on here can see the issue. How do you know you have no fuel pressure? Do you have a guage? Is the filter housing filling up?

the bowl is not filling up i even cracked the lines and turned it over nothing. The fuel pump runs but no pressure. I have not put a guage on it because it is not puping any fuel at all. My problem started with cold engine no power and white smoke. I didn't check pressure befor blue spring. Can the pump run and not pump??? thanks for your help.

Oh, OK I see now… Did you check the fuel filter in the HFCM. ( fuel pump ) I have heard of pickups cracking in the tank. With this you pull air in with the fuel and it runs bad when the tank get so low below the crack. What do you get when you pull the drain plug on the HFCM? Heres a crazy question, Is there any chance that the fuel got cold enough to gell up?
Are you running an anti gel treatment in the tank? You used the term cold , How cold?

I had a truck that the HFCM was plugged up terribly with diesel boogers. cleaned it out as best as i could because the customer couldnt afford the parts and labor of installing a new pump. pull the cover off and look inside the housing. youll probably see brownish reddish clay like and clear/white jelly in there with what looks like dirt particles in it. Clean it out as best as you can with your finger and with a shop vac try to get whatever else is lose that you couldnt grab out of it.

Check to make sure you didnt leave any parts out of the FPR and if the fuel bowl does not fill up top, you either have air before the pump or the pump itself is no good.

You bleed the system by cycling the key on and off a few times. There is a TSB on fuel tank linings coming apart and clogging the pick up, but I dont remember what years that covered. Is your fuel tank metal?
