Blunt force trauma ,causes fuel pump issue ?

[wyoben]

My 1992 sweet Chevy Silverado 5 speed 350 1500 4X4 ,had it's life ended by a hard rear end collision  ,with a 90 degree spin  T-Bone on drivers side ... If I recall correctly it was running ,after impact, briefly ...fast forward ,I'm trying to salvage the drivetrain  , but want to see how the engine survived before I disassemble  the truck  .Now I have a no start situation . I have  no  fuel delivery /no fuel pump  hum,  I've got power to the orange wire at relay, and I tried to jumper  orange / red ? ,   and also tried  12 volt  right to red ?fuel pump from relay on firewall ? I don't think there is an inertia switch on this  earlier  model ?  anybody got any suggestions ?

Could be a wiring issue at the pump itself or the impact from the crash killed the pump.

Im not wondering if it knocked it  clean off its  pickup  pipe ...the truck got  hit  really  hard ...
