You won’t “burn up the pump” on that fuel system with lift pump loss. Lack of fuel volume will lead to lack of fuel psi and the injectors will stop. Get the lift pump issue resolved, start it up and go. That kind of miles I’m really surprised they are stock injectors... replaced a lot of sets in the 180k-220k range. That age and miles if you see a “low rail psi” code you can either replace the in tank fuel pump, or on a couple occasions I’ve removed the pump and cleaned the inlet screen on the module. It will have junk in it, nature of the beast.
