You might be on the right path.
Something may not be letting power go to the fuel pump, or a broken wire.
Have to look and see what other things could stop power going to the fuel pump.
A few questions.
What happens when you turn on the key?
Any lights, any flashing lights?
Will it crank?
Did you voltage test across the 50amp main fuse?
Check this thread

Won’t start

2018 pioneer 1000. Tried to crank it and it just makes a vibrating noise in the relay box. Messed with them and got it to crank once. Then nothing again. Batter voltage is good. All connections are tight and clean. Was thinking solenoid or ignition relay??

If it cranks, the 50amp main fuse is good.
I see you are getting help at the other place.
When you get it figured out, post back here and maybe it will help someone else.
