Fuel pressure question
I can't seem to find anything about fuel pressure test on a 2010 f150 so I'll ask here.
I have another post about my truck having issues starting on cold start up but won't explain it all again here but will say that it starts every time its just on cold start it will turn over several times before actually starting.
Ok I tried doing a pressure test last night and the gauge read 0 when truck was turned to on position. I ten cranked the truck and gauge still said 0.
I had gas barely drip out of Schrader valve when connecting and discounting house so there is gas in fuel rail.
I can hear the fuel pump engage every time I turn key on and have replaced fuel pump relay and fuse so they are good.
Am I doing something wrong or is it possible the gauge is bad.

Usually never reads zero if you can hear the pump, try getting the truck running and connecting to fuel guage, i think spec if close to 50psi

Ok I got a new gauge from autozone and got 40psi on fuel rail so fuel pump should w fine. What I have noticed is that when I am parked on a incline nose up I have trouble starting the truck but if I park nose down it starts like normal everytime.
Does anyone have a clue what I can check next.

I'm not sure I'll have to google it. I'm pretty sure there's no fuel pressure regulator (If that's the same thing). I searched and never could find one and autozone has no preplacment part for the fpr.

I think your right about pulling the fuel pump and inspecting the pick up. If he's got some dirty fuel and the pick up filter is partly blocked that might account for the symptoms.

Thank y'all for all the info and I'll post after I install to let you know how the truck is running.
