Truck Repair: 1993 ford bronco 5.0 wont start, ford bronco, red button

Question
Drove my bronco to work, parked it and came back about 2hrs later to go get coffee and truck would not start.  Turns over strong, checked for spark GOOD. Not sure how to check for fuel or how to replace fuel filter, if thats even it. What do i do.  Truck as always ran good, like a top, purs like a kitten, what could have happen so quickly. It never ran bad, just died.

Answer
Hi Brent,
Over above the top edge of the floor mat, on the passengers side, there is a switch, with a red button on top.
Make sure the red button is in.
That is the fuel pump cutoff switch, and a bump can trip it. Slamming the door might possibly do the same.
