No fuel pressure...help!!
Sorry for cross posting. I am doing some searches too, but I am stuck at home and need to get to work. I have a 2001 f-250 7.3. Left for work this morning and the truck lost power about 1/2 mile down the road. Felt the same as it did when I blew a fuse on my fuel pump a year ago. Limped home and got it in the driveway. Popped the hood and saw no fuel pressue. (have gauge on the bowl) Turned key one multple times and never built pressure. Checked fuse 19 and 24, both good. Can't hear fuel pump prime. Put test light on red lead on pump and primed motor and did not get it to light up. Started motor and test light did not come one. Any thing to check other than the fuses...is there a relay somewhere? Help!

Have you checked the fuel pump shut off switch ? I have had them trip from seemingly minor jolts.
FUEL PUMP SHUT-OFF SWITCH
This device stops the electric fuel pump from sending fuel to the engine when your vehicle has had a substantial jolt.
After an accident, if the engine cranks but does not start, this switch may have been activated.
This switch is located in the front passenger’s footwell, behind the kick panel access cover.
To reset the switch:
1. Turn the ignition OFF.
2. Check the fuel system for leaks.
3. If no leaks are apparent, reset the switch by pushing in on the reset button.
4. Turn the ignition ON.
5. Wait a few seconds and return the key to OFF.
6. Make another check for leaks.

Yep I did check that out. I pulled the panel off and popped it up and then back down. Leaning towards the fuel pump relay...anyone know where that would be? Sounds like maybe behind the stereo in the dash?
