Default 2014 5.0 starting issue

This is the second time this has happened. The first time I left it overnight and it fixed itself for over a year... This time, it did not resolve overnight. It attempts to crank but acts like there is no spark or no fuel. I have checked all relays and fuses related to the starter and fuel.
Any suggestions would be appreciated. See video.

I did check fuze 27 and it looked fine.

Did you remove fuse 27 and look at its base contacts and look down in the fuse socket for burnt melted contacts.

When mine did this had to have a shop wire the fuel pump to the empty socket for Platimums/King Ranch models.Fuse 27 hadn't popped but the socket had fried

If it’s a fuel delivery problem I think the engine should fire with some starting fluid. Quick way to check. If it is a fuel delivery problem look into the fuel pump relay corrosion problem. Mounted on frame above spare.

I have that coming in today also. Only thing that I have seen suggested I did not get was the crankshaft position sensor. I have the Fuse 27 relocation and the Fule Pump relay en route.
Thanks for the suggestion!

FU27 relocation instructions have us abandon it. If the terminals aren’t burnt, suggest splice a wire to load side and run it out of the fuse box for future use. Used mine to power ditch lights.

Good Morning. Replaced F27 it was not crispy but replaced anyway. Did not resolve the issue. Replaced Fuel Pump Relay module and viola it started!!! It looked good but was apparently the issue. Thanks to all who contributed!

My 2011 was doing the same thing to a degree. It would attempt to start and get hung up with the starter running but never start, pull the key back and try again, generally would start the next time without issue but sometimes would take two or three attempts. I had a similar thing happen on other vehicles with the solenoid arcing out over time and would get sticky. I managed to rebuild those with new contacts to fix them. For the F150, I bought a new OEM starter but after about 9 months, the problem went away without ever changing it. I tried swapping fuses initially, that did nothing to help.
