Cadillac SLS
My 1997 Cadillac, will start up, but in about 3 secs. it will cut off, the info board reads theft system problem, I tried unhooking the battery, replacing the battery, but all tha did was nothing, I have managed to keep it running after it starts, but the P,R,D,N, indicator lights flash all at once and the fuel gauge doesn't work nor does the temp gauge, on top of all that my heater core is bad, it burst on me one day, do u think that may have shorted my computer board.
