recently i was driving my 87 supra and i just finished pumping gas and as i take off my stereo goes off then my gauges except for my mph gagues go off. its driveable but since im worried i pull to to the side of the road and turn the car off. as i try to turn it back on i get a no crack and check if my headlights go on and they are on. idk what it is its happend to me a couple of times already. the whole times this happend my headlights were the only thing that turned on.
