WHEN I PUSH ON THE BRAKE ALL THE ELETRICAL COMPONETS GO DEAD.I DID THE DIAGNOSTIC LINK TEST AND IT GAVE ME A CODE 41(CARBURETED MODEL)NO DISTIBUTOR PULSES TO ECM WITH THE ENGINE RUNNING.I DISCONNECTED THE BRAKE SWITCH AND ABOUT 3-4 MINUTS LATER I HEAR A DING SOUND AND EVERYTHING GOES DEAD AGAIN.IS THERE ANY WAY I CAN FIX THIS WITHOUT BUYING A NEW PROM OR ECM? ALSO,I FORGOT TO SAY IT DOES IT WHEN I TURN MY HEATER ON.EVERY THING GOES DEAD,BUT IT DOES COME BACK TO LIFE WHEN IT WANTS TO.

 

I FORGOT TO SAY ITS A BEAUTIFUL BLACK 1984 FIREBIRD TRANS AM ITS GOT A SMALL BLOCK 400(NOT STOCK) FLOWMASTER MUFFLER, ITS MY BABY AND ITS SICK
