Cadillac Repair: Cadillac Escalade-cranks wont turn over, cadillac escalade esv, volt ohm meter

Question
My 2003 Cadillac Escalade ESV died when I was coming to a stop on the highway and won't turn over.  The fuel is not pumping, I replaced the fuel pump and it still won't pump.  Have tried replacing the relays as well.  When I pulled the pump out it pumped but not when it's replaced in the tank
