1997 Buick Regal 6 cyl Front Wheel Drive Automatic 200k miles

I installed a new fuel pump on this car because it was'nt getting any fuel pressure and the fuses/relays all checked out good.I was thinking about running a wire from the ignition switched power source to the pump but I cannot figure out which wire out of the four going into the pump is positive.Can a faulty pass key kill fuel delivery or an aftermarket security system?

Power the gray wire on the fuel pump connector, the black wire is the ground from the battery positive post and see what happens
