Dead no fuel pump issues

I have a 2000 6.8 V10 Excursion that hasn’t given me any problems until this week. I was delivering a tractor and I arrived turned it off but the max AC was still on. I needed to move it forward so I just started it up and moved it forward 30 feet and turned it back off. When I was ready to leave after 10 minutes I hopped in and fired it up and it wouldn’t run it chugged and had no power then it died and won’t start.

I have gotten it to run with carb cleaner so I determined it was a fuel filter or pump. I changed out the filter still wouldn’t start, changed out the pump still won’t start, tested all fuses and relays still won’t start. I have 10 volts on one lead and 6 volts on the other at the fuel pump connector at the tank I don’t know if that is right and can’t find anything that tells me. If I disconnect the cutoff switch the 10 volts goes away. Any ideas?

With the connector disconnected at the pump the pink/black wire should have 10+v, the other wire is ground.

"If I disconnect the cutoff switch the 10 volts goes away" - normal

I would guess it could be your IAC valve.
