It's someting electrical prob not the pump or the ECU
update checked all the wires in wiring harness they look good. Would it be a relay somewhere? Also my mileage is listed as - - - and my trip display is - - - also WTF

The gas gauge is reading correctly

Could also be faulty PATS components. If you got a new PCM and didn't have the PATS reprogrammed, it will do that same thing.
so the ecu would control if the fuel pump turns on?
Yes. And if PATS is eff'd up then it won't spark OR fire up the fuel pump because it thinks you are trying to steal the car.

sweet because i ordered a new ecu through focussalvage and a new light switch cuz mine is bad also thanks
did you re-set the cut-off switch? on the passenger kick pannel there is a switch you can re-set, its in case of a accident and shut off the current to the fuel pump. Sometimes they go defective.
