Default 1998 Chevy 1/2T 2wd 5.7 cranks but won't start

Shut it of when I got home from work Friday evening and Saturday morning it would crank but not start. Can't hear fuel pump run. I have battery power to the relay but no keyed power to the relay. No DTCs stored. Originally thought the fuel pump, but with no keyed power to the relay, begining to sound like ignition switch? Not sure of the electrical schematic, need to review that yet. Does the fuel pump relay get it'* keyed power directly from the ignition switch or through the ECM? Thanks in advance.

Welcome to the forum.
Hoping someone can post a schematic diagram to help you out here.
I would want to know also if they may be a blown fuse, or even if you have a chip ignition key, as the security can also interfere & shut off the fuel pump.
Any other dash lights, scan for codes?
