No start after back up collision
I was backing my F350 out of driveway and hit a brick column. The truck stalled out and will not start. I checked the fuel shut off and it was not tripped. this was a low speed jolt. When I turn the key I hear the fuel pump send fuel to the filter housing and then stop. The truck will crank but not fire off. I checked all the fuses and they are good and no trouble codes found.

I second/third the fuel inertia switch. I can't come up with any other explanation and those things can trip very easily. Take the kick panel off and check the plug connection and try pressing the button.

I found the trouble. My fuel pressure regulater senesor on the back side of fuel filter came off. There is a flat presed steel nut that holds it on that backed off. Thanks for the help.

There is no fuel pressure regulator sensor. It's a spring and plunger built into the fuel filter canister.
What you are describing sounds like the IPR nut. Are you sure it was on the fuel filter, and not the HPOP. They are adjacent.

Do these trucks, F350, have an inertia switch? I ask because 2 weeks ago I was hit in the rear by a Honda that had been hit in the rear by an 18 wheeler with a dump trailer full of dirt and my truck NEVER shut off once. I looked in the rear view mirror, saw it coming and hit the throttle (notice I didn't say GAS!). It hit hard enough to fold both mirrors in but didn't shut off.

Yes, they are supposed to have an inertia switch. The primary power from the fuel pump relay goes directly to it, then out to the fuel pump motor.
HOWEVER, if it is "tripped", it should illuminate a light on the instrument panel that reads "Fuel Reset" (or similar).
Having said that, the above two statements are based on the wiring diagrams, and I gotta' admit that I can't find the spot on the instrument panel, nor have I looked inside the passenger's kick panel to verify it.

Fortunately, the truck's never been whacked hard.
