Help! No Full Power Mode

I recently inherited my father's 1990 ZR1. Everything seemed to be working correctly except the occasional FX3 hiccup. After a couple weeks of driving I have run into some ABS issues. I am waiting on a lateral accelerometer to fix the last code. I did notice when my "service ABS" light came on the "engine full power" light stopped lighting up. I've tried switching the key on during hard acceleration and nothing. I hear all the normal pumps and relays activate at startup. I've also checked the switch to make sure it's operating correctly. Should the "full power" light come on during bulb check? Is it possible for the ABS codes to have disabled full power mode? Any help you all may be able to provide will be very much appreciated.
