I was changing my one of my fuses because it was blown, when I was done I went to try and start my car up. It was just crank and not start. So I left the key in the ignition with it just turned to the on position. The theft light flashes over and over with dashes on the odometer reading (———————). The car started before, this is the first issue. I know the previous put a SIMCO dash in from another junkyard GT. It started fine with no issues then, why is it causing some now?
