...spins? i put a starter on it (pontiac firebird 94 - 3.4L) the other day, and the car wouldn't start up, so i noticed a wire that went to a sensor torn apart form the sensor just above the starter, what is this sensor? So anyway i put it together and the car started fine. I drove it home and the next morning i got a small backfire and just a spinning motor, no start up or anything just the motor turning.. please advise
