Fuel pump fuse???

Starter relay and o2 sensor won’t affect fuel for starting.

Have you checked the fuel pressure relay?

Do you have a multimeter?

Fuel pump power wire should see 12+ volts for about 2 seconds after turning the key. Then that wire should be 0 volts until engine start. One wire on the pump wiring should be hot and one should be ground. There’s also fuel level sensor wires there. I don’t have a book for that new of a truck so I can’t tell you which wires are which, but if you don’t have a good 12v and ground at the pump for the pump, it’s not gonna work and you need to start tracing that circuit back until you find the problem.

I think you mean fuel pump relay.

Pump, pressure, whatever

We don't want to confuse him any more than he already is.

O2 sensor will not prevent starting.

it appears the fuel pump is bad
